Let me tell you why you don't see this happening more often.
I did this on a project a few years back. I replaced a paper workflow process that was taking up two people each in three departments with a web-based workflow that increased visibility, dropped turn-around time from days to minutes, increased accountability and accuracy and trimmed those 16 person hours of processing down to 1-2 per department.
Everyone who directly interacted with the new system loved it. Numerous edge cases that would have been lost in high-level review were caught and integrated from day 1 due to my actually watching people do the job for a day or two per department. The solution has been rock solid (minor maintenance only) for five years.
And I almost lost the job.
The people who sign the checks were furious. The balance of political power between departments were thrown for a loop. One head in particular treated the thing as a near-existential threat. His entire concept of his job revolved around being the authoritative interface for retrieving and maintaining pieces of data that were no longer exclusively under his control. Another flipped out because middle management saw the results as cause to reduce his headcount and budget, and thus importance.
These two departments fought for months, refusing to contribute their shares of budget that were pledged toward modernizing this system.
On a technical and practical level, it was the single best experience I've ever had as a consultant. On a personal and economic level, is was one of the worst. It was some of the hardest money I've ever tried to collect. It was some of the most time and energy I've put into the political and 'sales' side of a job (the part I treat as a necessary evil, but very much evil). The corporation has made out like a bandit in the long run. But I paid the price.
It's simply too easy and financially rewarding to allow a client's political nonsense to screw up every stage of a project. I have less stress, the people who pay me are happier and I bill far more hours.
As with most software, internally developed software included, you don't see better projects more often because the incentives are horribly perverted and stacked against it.

My favorite thing like this for a purely technical topic was a project where there was a mandatory requirement to NOT support ethernet auto-negotiation.
Why? The company had a long-standing policy of manually setting speed and duplex to ensure that there were no duplex mismatches. The was a team of 6-7 people who would audit servers and check switchports, and they produced a report was issued every week, and reviewed by the CIO and other luminaries. People would be shamed for errant configurations, as only the auto-negotiation team could configure NICs.
The director who controlled the auto-negotiate squad was politically powerful, and got all sorts of power out of it -- including banning GigE. As late as 2010, this org was deploying dozens of 100MB NICs to ESX hosts to get sufficient bandwidth. They also purchased 100MB NICs for desktops.

I don't know if you were around 10 years ago, but there used to be real problems between certain network cards and switches that prevented autoneg from being 100% reliable. For any company of a certain age I would not be surprised to see a policy like the one you describe.
The surprising thing isn't the policy. The surprising thing is the persistence of the policy even after it's no longer beneficial in any way. It's been more than a decade since Ethernet auto-negotiation became reliable. During that decade, that company has paid for a team to go around and do manually what could have been done by an automated process for a trillionth of the cost. That's a staggering amount of waste.
The policy has to be proven to no longer be beneficial, and I'm pretty sure every major OS has had a way to remotely set the card to a fixed configuration or autoneg since around then, but that's a separate issue.
Thats why policies, like contracts, should never be evergreen. Policies simply amount to internal contracts and any company that does not regularly review and refresh them is doomed to this kind of waste.
But who will regularly review the policy on reviewing the policy on regular review of policies?
Have you ever worked at a company big enough to have IT policies like this?
like the parent or evergreen? No I have never worked anywhere that promoted such abject waste through "adherence to policy" but I likely would not have chosen to work at such a place to begin with.
Absolutely... IIRC, the IEEE standard was ambiguous, and each vendor implemented things differently. I think the standard was "fixed" in 1999... This situation happened in 2009!
But the technical problem wasn't the problem -- the issue was that they created an inquisition that had outlived its purpose.
But the technical problem wasn't the problem -- the issue was that they created an inquisition that had outlived its purpose.
For a long time that was my first question anytime there was a network problem that wasn't a simple solve on the client.
Step 1: Disable/Enable interface
Step 2: Call NOC: "Can you tell me what this port is autonegotiated to?"
And horseless carriages used to be less reliable than horses. The problem is the longstanding nature of the policy. They were paying a team of 6+ techs, surely they could afford a process-review/technical updating meeting once a year? And surely there's a better way, such as standardizing on a brand of NICs and of switches, and being done with it. If you can't push an update to the machines to prevent this anyways.
Besides, it shouldn't cause cascading failure so the worst case scenario is a tech call, the same as for an unplugged cable.

Several comments here indicate that this practice is outdated. I disagree strongly. Even in 2011 autoneg is flaky on many switches - in a recent shipment of ~100 machines, ~5 of them autonegotiated to 100mbit instead of gigabit. And these are name-brand machines with name-brand switches.
Forcing duplex and speed with ethtool is still relevant.

It sounds like you have either crap NICs or crap cables.
Great anecdote that illustrates this principle observed by Upton Sinclair:
"It is difficult to get a man to understand something when his salary depends on his not understanding it." (from I, Candidate for Governor: And How I Got Licked)
"It is difficult to get a man to understand something when his salary depends on his not understanding it." (from I, Candidate for Governor: And How I Got Licked)
Speaks well to why money won't ever get out of politics: it's not in the interest of the politicians.
Well said, and the exact reason I moved away from consulting after a decade of doing it.
The developers often get blamed for "not understanding how real people use the system". Most features are requested by C level people who have never actually used the system.
While consulting, I've actually been told NOT to talk to the users who will be using the system. In a large enterprise it is often about power and politics, it is rarely about building value and increasing productivity.
Vote with your labor, work for a small company.

For these political reasons, it's important to have executive-level support, or else it would never fly. My first job out of school was doing exactly as the gp suggests at a national telecom. Job-shadowing people in their day-to-day work, understanding their problems, and turning around web/desktop apps within days or weeks to solve their problems. We had huge success. We won an international award for what it's worth (Stevie Awards for Best Support Team). We saved our company millions, and were one of the keys for the company to survive a big labour dispute. Can you believe that previously, for a national telecom, all orders for corporate telecom solutions had to be gateway-checked by a single person? We democratized stuff like that so that processes could be much more flat. No need for requirements documents, no change control, complete freedom of creativity, complete freedom to decide what work to accept, etc. I know how that's sometimes necessary for big projects, but for small high-ROI stuff, it was beautiful.
The other side of the story is that we ran into huge political problems. Every day, someone was trying to kill our team because we were making the traditional IT groups look bad with our turnaround time and solutions that worked. On the other side, we were automating things that people didn't want automated. If we didn't have support from the CEO down through a specific chain of command, we would have been killed within months, if not weeks. We didn't even call ourselves developers. Our official position title was business analyst because then IT would bug us less. We weren't even part of the official IT department because those guys couldn't get outside the box. So we were just a small group of business analysts who tried to hide until we were too successful to hide anymore. That's when the attacks really started coming. And then we continued to be successful, and then they started trying to copy us instead. Last I heard, that team's unfortunately been swallowed up by the bureaucracy now, and is a shadow of what it once was.
Fascinating experience.

Having consulted with various branches of the US Govt for about 13 years, I can safely say that this is almost exactly how most govt projects work. They are far more often about satisfying political objectives for bureaucrats than helping the user.
This is why I'm far happier now consulting to startups than to large corporations or the govt.

From my experience in consulting (over a decade), I have to agree. It's extremely difficult to convince people to do things right. It's sooo much easier to give a friendly grin, a firm handshake, maybe dinner or a round of golf and state emphatically that "you need an ERP or CRM or other three-letter acronym".
Ultimately, it comes to corporate Darwinism... the companies that evolve reasonable processes prevail. Others will only leave a fossil record. Unfortunately, we have governments as well as corporations.

And yet some of us keep charging at windmills, trying to do what they allegedly engaged us for. With about as much success.

I have less stress. But have I done my client a service? No! I've helped enable the flawed behavior that led them to engage me in the first place!
Are you a consultant because you want to earn a big paycheck without much stress or because you want to make teams better? For me, the latter comes first.
I even go so far as to tell the client when I believe that I can no longer add value equivalent to my cost: when they no longer need me. My job is, ultimately, to become superfluous: to make them better then get out of the way.
Now if I was engaged because of that delusional thinking, that's another problem...

This needs to be a post in itself!
Oh God. I sympathise I really do. I have been in that particular situation twice and never again. I am very wary about internal politics in certain types of organisation and like to have a full overview of it way before commiting myself. If that's not possible I don't take the work.
I admit to liking waterfall myself (it suits the kind of work I do) and if well done by competent people and for certain types of project its the way to go ...

There is process called Contextual Design. Part of it talks about treating the tacit knowledge of a workplace like a very necessary requirement for your software. So that means including the culture of the workplace in your reqs.
It sounds dumb at first but it makes perfect sense. What you did at that place was to apply a bandaid to a fracture where it really should have been a cast. But you didn't know it was a fracture because you didn't look past the swelling to the root cause of the pain. This is nothing new, consultants have been loathed for this very reason for a long time now.
That was me telling you how to do your job. If you wanna know more, google it. If ya got offended, have a nice day!

Personally, I see a very clear line between culture and politics. The people of the various departments didn't have any conflicts. It was strictly between department-heads.
And, for what it's worth, the C-level types loved the project too. What I did was replace a wooden peg with a modern prosthetic and upset the guy who was selling wood oil for conditioning the peg and the guy who sold the leather straps [1].
edit: That said, sure, it'd have been less stressful if I worked in the politics up-front. I said as much. But I've done it that way enough to know it would inevitably have compromised the system. And my post was a response to "why aren't the systems better?".
[1] and him, only because he couldn't see past the loss of the peg-strap business to see the gain of business making, maintaining and adjusting straps for the modern prosthetic.

Seems to me the C-level execs should have given you more cover. It's their job to manage their organization, not yours. This strikes me as a failure of leadership on their part.
Sure. But have you ever found a large company that paid any of their bills on time? Particularly after they have the deliverable, their incentive is very much to allow their middle managers to continue inventing 'concerns' and delay payment.
Everything was couched in "We're really happy. We're not sure why Bob isn't. But we'd really like you work with him to sort that out."

You are right, there IS a line between culture and politics.
But thats the thing. You should count politics as part of your requirements too, or thats what the theory states anyway.
For example, lets say you digitized an inventory form for a sales dept of a plastic company. By doing this, you effectively removed use of a pen from the 'system'. Now what politics could you possibly be affecting by eliminating use of a pen? Well, you could cause an uproar between the finance dept and the sales dept. Finance says that the organization's major stock holder is a pen company and the sales department must use pens (for whatever reason...lets pick advertising and promotion).
Now your system made the world efficient but it failed to account the current work practices of your client. You, sir, just screwed up.

Sounds a bit like the guy who had some really good advice to give, but didn't take into account the politics and context of the forum he was posting to, tagged it with a douchey comment at the end, and got downvoted and ignored.
Interesting point until the twatty comment at the end.

I just love how much sound advice we discard because of our feelings towards someone/something.
Ever read Stuart Sutherland's Irrationality?

I agree with the sentiment, but how can you know to trust someone's advice if they're acting in a way that's obviously very socially stupid? (I'm not huge on excessive politeness, but I think it's quite stupid to be aggressive for no reason. What purpose does that serve? Why should I trust the advice of a person that acts that way?)
I assume by treating their argument in a rational non-emotional way...
if you tell somebody something while slapping them in the face, don't be surprised if the only thing they remember from the interaction is the slap.
on the other hand, sometimes people need a good kick in the ass, so who the hell knows!

This is why corporate software like SAP is so bad. The guy who writes the cheques to the vendor doesn't do timesheets or whatever. His secretary does his expenses and his travel and his holidays. He never touches the software apart from to look at the dashboard and the final generated reports (which will be whizzy). He literally doesn't know it's miserable to use, and unless "subordinates satisfaction with corporate apps" is his bonus metric, literally couldn't give a flying fuck even if he did know.
Say what you will about large corporations but at the very least they can get this right. I'm working for a 4,000+ company now and we take these steps very seriously during our Engineering design. Also part of the job is working with vendors (Oracle, HP, others) who send people on sight from around the world to work with us (the client) and properly interview for the right knowledge.
Call me bias, but a lot of smaller companies overlook tried and tested standards. Proper requirement elicitation was documented in IEEE Computer Society SWEBOK prior to 2004 and even that is a summary of important knowledge to Software Engineering profession. Why is it that when a new company comes along with a truly innovative concept they feel they can innovate the rest of the process as well?

Part of why I love my current job is because we focus on the actual users of the software and get feedback from them, not the executives.
It made the initial sales much harder, but the results are much stronger and we've gained such a strong reputation that the software almost sells itself.

You're exactly right – but you realize, there's a whole group of people -- a whole discipline, in fact, that does exactly what you're talking about, right?
We're designers.
And we do have & run consultancies. Places like IDEO, Frog Design, Adaptive Path, RED, Doblin (Part of the Monitor group now), Gravity Tank, Teague -- and many, many more.
User centered design processes should be backed up by rich user stories, that come from real user experiences. The only way to do that is to go out in the field and get exposure to the who, what, when, why and how of what the users are doing, want to do/need to do and how they use your product/service.
And if you do it right, you can make a much more successful product that sells a lot better while actually doing some good for the users.
Not a bad line of work, IMHO.

This is exactly how we did process review / analysis at my last company. It was always awesome to uncover the differences between what the stake holders thought the current process was, and what the people actually doing it did.
After that we tried to reconcile the differences and usually made the in-software process a mixture of the two (where possible)

Few seem to realize that source code is but the most thorough "blueprint" of the product. That compilation - to wit construction of the actual product from the blueprint - is nigh unto instant and free means everyone overlooks it as the actual construction process, akin to actually building a bridge from detailed plans (except you get one shot at building a bridge, while you can recompile every few minutes). Ergo, "analysis", at greatest detail, _is_ coding. That we iterate so much comes from the continued newness of the technology and the relative complexity of the products; bridges are well-understood and iterating the design of one is minimal.
To the site's point (or missing thereof), the notion of "don't start coding until the analysis is complete" is a gross misunderstanding that coding IS analysis.
The inanity of reinventing the waterfall model is obvious to HN readers.

It sounds like you're saying something similar to this: http://www.developerdotstar.com/mag/articles/reeves_design.h...
Meh. This is hardly the most ridiculous thing I have seen on the internet. I am sure this methodology will work sometimes for some clients. Heck, I bet a lot of startups here on HackerNews are using similar methodologies - but without the early usability testing. If nothing else, at least this company are differentiating themselves. Haven't seen a lot of other consultancies get posted up here on HackerNews.
Every project is different. We should try and not be too dogmatic about these things.

The ridiculous aspect of this page is the quote "We've invented a development process tbat's completely unique in the industry.", after which they describe a process that looks entirely like waterfall. It's an entertaining fallacy.
The company I work for has had a very similar process for years. In fact, it's stated much better within the first line of text on the homepage.
I think a workflow approach is a better way to go for the client, but even our approach was inspired by other companies who have embraced a transparent workflow methodology such as this.
It's painful to see a company claim it as a first.

This was posted on HN so that we can make fun of it, and I think we're right to do so. You can be as wishy washy as you like about different situations requiring different processes, but have you ever seen somebody successfully isolate software engineering from coding and put them in sequence?
Waterfall is actually considered the very best model for software development, when the requirements are known up front in excruciating detail.
An average project experience around 25% change in requirements. Hence waterfall is highly unsuited for the majority of projects, since it does not handle requirement changes well.
However, in a few areas such as aeroplane control software, space shuttle software and similar, waterfall is indeed the optimal development process.
Different projects DO require different development processes. That's not wishy washy, it's the reality of software engineering.
Mindlessly applying your favourite development process to all projects, be it waterfall, scrum, evolutionary prototyping, spiral development or what have you, will very likely result in failure, if the process does not fit the project.

"Waterfall" was defined in a paper describing how NOT to do software development. The problem was that very few people at the time had any process at all with software so seeing this they gave it a try.
The paper you and "gujk" are referring to, I believe must be Winston Royce's paper.
It's wrong to say that the paper is a description of how not to do software development. Rather, it's suggestions for a set of improvements to the process, while retaining the sequential nature. In the paper, Royce considers waterfall to be a good process, but with flaws which result in high risks. These flaws is what he addresses in his paper.
His suggested approach is derived from pure waterfall, and is very much similar. It falls into the "modified waterfall" category of life cycle models, together with a group of other similarly waterfall-derived models.

He said, and I'm quoting, that the pure waterfall method is a good concept "but is risky and invites failure." He described how it leads to massive cost and schedule overruns. It was definitely a process that he did not think you should use.
His proposed solutions that you call "modified waterfall" are modified quite a bit. (As an aside, he never used the word "waterfall.")

I have read the paper multiple times over the years.
The quote "is risky and invites failure" is correct. However, another quote, even on the very same page:
"However, I believe the illustrated approach to be fundamentally sound. The remainder of this discussion presents five additional features that must be added to this basic approach to eliminate most of the development risks."
These suggestions are to 1) Add an additional (preliminary) design phase, after requirement analysis. 2) Much greater documentation. 3) Perform the entire sequential process twice (not x amount of iterations, just two times). 4) Additional activities and documentation during testing phase. 5) Involving the customer.
His diagrams require close scrutiny, as on first inspection it seems the process is markedly different, when it is really not. It is still an entirely sequential waterfall process, just with an extra phase (preliminary design).

These suggestions are to 1) Add an additional (preliminary) design phase, after requirement analysis. 2) Much greater documentation. 3) Perform the entire sequential process twice (not x amount of iterations, just two times). 4) Additional activities and documentation during testing phase. 5) Involving the customer.
His diagrams require close scrutiny, as on first inspection it seems the process is markedly different, when it is really not. It is still an entirely sequential waterfall process, just with an extra phase (preliminary design).
"waterfall" was a made up term invented in a paper to describe a hypothetical development process, not an actual process.
The term "waterfall" wasn't coined by Royce in his paper. His paper was a set of suggestions to improve what later became generally known as the waterfall process.
And Royce was ultimately advocating an iterative method (rather than a strict waterfall), not unlike most agile methods today, although his cycles were much larger.
If one is interested in software development methodology, I strongly recommend taking 15 minutes to read the actual "waterfall" paper[1].
Poor guy, Winston Royce is one of the most misunderstood folks in the industry.
(By the way, curiously enough, Royce's son William was a major contributor to the Rational Unified Process.)

He wasn't advocating iterative methods in the agile sense, in fact he calls for "complete program design" before any analisys or coding, along with intensive documentation, planning, controlling and monitoring. An iterative approach to development drops nearly all of those.
The graphic where he shows cycles going back stages is used to exemplify failure, which he proposes to fix via the strict practices above.

Or, he could be advocating the most agile process that the technology of the time (1970) would allow. Remember that there were no desktop computers, no internet, the programming language C was just being created.
Agile processes don't depend on technology, just people, paper and communication, in fact technology can be a burden sometimes.
Just in case someone from the future misunderstands this: I don't mean that agile drops analysis, documentation, planning or monitoring (they are essential to it) but it leaves the "intensive" and "before" parts out.

Development processes very similar to todays "agile" family, existed back in 1970. "Evolutionary prototyping" for example (a member of the "prototyping" process-family), is one of the precursors for todays agile practices.
Most of us would probably agree that their method is worse than more modern methods, but spending time making fun of them is like making fun of someone for driving an old car. You could be working on your startup right now.

You have a choice of koolaid. The waterfall brand is implicit in the statement "We don't write a line of code until we know your business as well as the people who keep it running every day." - it is founded on the assumption that you can finish requirements for the entire system before starting to deliver working software, and no feedback or iteration is needed.
My experience is that for the majority of software projects, this assumption is horribly broken. And even in fairly well known problem domains where it might work, for the majority of business users wanting new software, the ability to communicate every detail of what it is that they want is horribly lacking.
Scope creep, architecture problems, unanticipated requirements etc. can and does break waterfall projects; this was well known 10 years ago. The probably of it going wrong rises with the size of the project, and it's a curve that's well above linear.
There are two ways out: You can plan for change or you can make the penalties against change more severe - roughly, do even even more big upfront design and penalise change requests; or do less of upfront design, iterate and embrace change. In many cases the "big upfront design" way is impractical in time and expense.

This was well known 40 years ago:
The most deadly thing in software is the concept, which almost universally seems to be followed, that you are going to specify what you are going to do, and then do it. And that is where most of our troubles come from. The projects that are called successful, have met their specifications. But those specifications were based upon the designers’ ignorance before they started the job.
--Douglas Ross, 1968 (http://homepages.cs.ncl.ac.uk/brian.randell/NATO/nato1968.PD..., p. 32)

Very true, and I should have picked an earlier date. But I was erring on the side of caution, and it somewhere between 1990 and 2000 when agile methods, which explicitly reject big upfront design, became mainstream.

I also have the choice to ignore all the methodology snake oil salesmen and actually write software. Every "methodology" is bullshit. The new ones are not any less bullshit than the old ones. The fact that your response assumes I must love the old version of "follow our stupid manager nonsense" is really pretty sad. You honestly can't even imagine a world where I might think all of the bullshit is equally worthless? I have to be an adherent to one of these religions?

You have chosen the "just code" brand of koolaid. Results are highly variable, its hard to manage and it doesn't scale. But YMMV.
That response is even sadder. I haven't chosen the "just code" koolaid, but your religious beliefs are so deeply ingrained that you can only perceive me through that lens. As a result, you miss out on the great big world of "every situation is different and you should do what is appropriate instead of what some dipshit hawking books and seminars says".
Actually, both of my previous comments made mention in passing of situations where I though a method wouldn't work. You say "every situation is different and you should do what is appropriate" but make no mention at all of which method is appropriate for which situation.
Books and seminars, we got these, but good agile is done by adding in some open source software tools, a whiteboard, pens and cards, and people with enthusiasm and an open mind. The last one is most important.
If we're still talking about the original post, then absolutely it's a belief system. Not a very well thought through one, though.

Pure[1] waterfall is doomed from theoretical point of view. You cannot control a system without a feedback loop, unless you have a 100% accurate knowledge of system's state and future evolution. Waterfall lacks feedback loop => you can't really expect much from it.
[1] - in real life there's always some kind of feedback loop in the process; I'd argue that the primary reason why Agile methodologies seem to work better is that they have a much, much tighter feedback loop than waterfall.

Whether or not one drinks the koolaid doesn't matter much.
15 years ago, 1-3 year release cycles were the norm. Now they're uncommon, and becoming less and less so. Some well-regarded shops (e.g., Etsy) now release many times per day. This isn't driven by what process is fashionable; it's happening because of improvements in technology and the way the Internet has shifted everybody's expectations.
Whether you're officially using some Agile(tm) method or not, you'll have a lot in common with those folks if you meet user demand for faster delivery. There are some niches that are lagging on this trend, but my pals in those areas still feel the pressure. They'll still be able to be waterfall-ish for a while longer, but I doubt it will be forever.

It really depends on what kind of software you're writing. Sure, startups writing web apps for casual users can have super short release cycles.
But imagine "agile" development for commercial airliner flight control software.

I can. I'm seeing automated tests. A whole lot of automated tests. Unit tests, performance tests, integration tests, executable specifications, tests with real hardware.
I can be done; you have to optimize for what's important to the project at hand.

People have been doing it with medical devices, so I don't think it's impossible. I agree it would have to be done differently, but then avionics waterfall has to be done differently than order-entry systems waterfall, so that's nothing new.
I actually once worked for a place that didn't have this exact process, but they had a heavy process I'm sure nobody would describe as agile. And it worked pretty darn well.
They designed educational games for early elementary education. Every game activity was hashed out with a working committee consisting of an educator, a technical writer, an artist, and a programmer. They'd take a few hours and talk about the concept that the kid playing the game was supposed to learn (say, measures of weight), then they'd brainstorm ideas for potentially entertaining scenarios in which the concept could be explored (say, a flea circus), then they'd start to storyboard various activities and interactions.
Then the tech writer would produce notes, people would review them, and 2-3 weeks later, they'd do it again, refining concepts and interactions.
This process would stretch out over months, and by the time it was finished, the tech writer's notes essentially comprised a complete state machine for the activity described in English on paper. And the artists/media people had the assets for you in the right media formats. Usually sensibly named. Programming was generally pretty straightforward.
You know how a lot of the time that non-technical "idea guys" seem to have this terrible attitude? "Hey, I've already done the hard work of coming up with the idea, all you need to do is translate it into code."
This was one of those rare situations where it was often more or less true. But it was because the people coming up with the concepts were really part of a creative and disciplined process where they had to come to grips with the details in a way that usually only programmers have to.
Oh, and after things were done with programming, they had a QA team compare it against the spec and an educator's review.
They produced a pretty good product. Sometimes I think it's a shame I didn't stay longer.

I think this process would work pretty well for educational games as each game was a self contained thing.
As a teacher myself I do often incorporate a game (computer based or actual paper, dice, pieces), an interactive Web site, a video or other objects into a lesson. I also direct students to Web based interactive content as part of homework along with 'traditional' work.
In effect, my lesson planning is the 'interface' between the (no doubt well coded and engagingly designed) objects your team designed.
I suspect, from my own interactions with the business applications used in the largish educational institutions that I work in, that it might be harder to use this model when the interactions between the individual activities get complex...

I agree with you. After a few years in the field, I'm now convinced that it is how most software is made. Even in the "Agile" startups and such, processes are often implemented as waterfall, or large parts of projects comply with the waterfall model.
While it fails sometimes, there are plenty of success stories about the waterfall model, like it or not.

Actually, this is refreshingly honest compared to the "agile" methodologies. Having worked with plenty of supposedly agile consultants I can tell you they basically do waterfall it's just their cascading stupidity starts with code and then wanders around writing unit tests until the client is tapped out. At least this is doing some actual user interface design and usability testing.
Then again, I doubt these guys do this since it's all marketing.
Then again, I doubt these guys do this since it's all marketing.
The difference between "agile" and "waterfall" isn't that easy to pin down.
Some people think of "agile" as just going through their full waterfall process every month or every two weeks.
Other people insist the core of "agile" is TDD, others claim nonsense, TDD is just as much part of "waterfall", and yet others don't see any point in TDD for their "agile" process.
tl;dr:
It's all bullshit, all the way down.

Really? Claiming to have invented the most well know and also the worst software development process is honest? It's a bold-faced lie written only to get clients.
One can only imagine what actually happens in communication once they have a client. If the marketing is a complete lie, then I can't imagine the company itself can be trusted.

Most "agile" consultants you know start coding from day one? If so, I now understand much better why you dump so much on agile.
I had myself a nice little nerd slap fight on twitter earlier today about this post. "Agile" without up front planning and research is just dangerous.

Oh, now we're going to get into the perpetual argument of what is really agile? Agile's like porn. Everybody who does it claims they know what it is, but nobody can define it. Instead they call "successful" projects properly agile and failures are just shoved under the rug with claims they didn't do agile hard enough.
So please, save your criticism that you know what is and clearly I don't. You can't define it, and if you think you can I know you don't follow it.

God damn, Zed. You sure jump to conclusions that people are going to fight with you! Not that you remember it we've met twice and had perfectly normal conversations.
No, I agree, dammit! So take that!
Although I can see where you may have misread my honest question as rhetoric to indicate conflict. That was, as I said, an honest question--though perhaps missing a few words. I was inquiring whether the "agile" consultants you've known start coding on a new project from day one of the project indicating that, in those cases, they aren't taking much time at allfor research or planning.
Agile is a broad label that doesn't make a lot of sense. I've been in the biz 16 years. If there's anything that I preach it's "it depends" and "YMMV". Please don't assume we're all out to get you or that we all believe that we know better than everyone else.

Am I in the minority who uses both agile and waterfall methods?
The long and the short of it for me is this: There's two ways to solve problems. Agile helps immensely when you are figuring out how the solution would work. When you're solving a problem that might be solved in manual processes largely, Waterfall can help a lot, but not alone.
For unknown solutions, agile gives you a lot of iterative benefits.
For known solutions, waterfall with some agile feedback loops gives you incremental benefits.
What's the difference?
Sometimes, in a business, they have a great process already. It's in paper, or multiple systems, but they have their way of doing things that works. I believe it's called their competitive advantage.
Othertimes, a business is facing a problem for the first time, and wonder "how do we solve this". In this case, doing a big upfront design is a waste of time, starting small and staying flexible is most important.
For me, this mindset of doing both is critical, not one or the other at all times. You simply miss out on too much if you don't use agile, and you run around too much if you ignore waterfall when a solution exists.
Waterfall works where it's a known process, like building a house. You can have agile loops in there when building a house and improve it as you go.
When you're trying to build a new building that's never been built before, an iterative, feedback-centric approach like Agile is a lot more beneficial.
If a company focuses on taking something like Waterfall and introducing feedback loops (agile) like this epicenter thing, is it not a bit clearer than the black-box voodoo out there? Maybe it's just me, but I applaud anyone trying to make software easier. It just shouldn't be a dogmatic, or religious dismissal.

Its really not quite as bad as it looks at first glance.
Step 2: "we design an interactive prototype" allows them to get the feedback that really makes more agile methods work. You don't need to constantly iterate during development if you iterate properly during prototyping. I certainly wouldn't advocate this method but its not a vanilla waterfall method.

If one reads the paper most commonly cited as the source of the waterfall methodology he or she will discover that the author of the paper recommends doing something akin to prototyping before designing the real program. The paper is actually a critique of the process now commonly referred to as waterfall and the author does not recommend using the process as first presented in the critique.

That they insert what amounts to a single early design iteration hardly rescues the inanity of "hey! I sliced bread! this is awesome!"
Agreed - this isn't as poisonous as the usual waterfall techniques are.
And frankly, if you're working on a massive project that has strict requirements (either regulatory or functional) then up-front analysis has a lot going for it.

The original waterfall spec. describes the usage of prototypes. I wrote a small review of it a few weeks ago: http://emtrics.com/2011/10/17/software-development-a-little-...
Sadly, I don't think this is a joke.
Method as described:
"Analysis
We don't write a line of code until we know your business as well as the people who keep it running every day. "
Method as implemented:
"Analysis
We never write any code"
This doesn't look like a joke. Dangerous. Anyone who has done this methodology runs screaming for an exit after a failed project or two.
Not so fast. This isn't something new or strange at all. We are doing this for years with great success.
But maybe you know this method as these steps (which are the same): Concept -> Functional design -> Graphic design -> Building -> Testing -> Deploy.
Nothing strange about that. Take a look at the IBM Rational Unified Process http://en.wikipedia.org/wiki/IBM_Rational_Unified_Process
I just think this is a hyped site trying to sell there book.

Waterfall isn't bad in all circumstances. Lockheed Martin isn't iterating a jet into the side of a mountain 100 times until they get it right.
Perhaps not.
But they're probably running a computer model of the jet (and its systems) under various simulated scenarios.
They're also probably building some full-scale mock-ups to test in wind tunnels.
And they also have test pilots to fly things which sometimes never make it into wide scale production.
So, I'd argue that there is some iteration going on there.

Which is also what the company is claiming to do. I.e. we will create a prototype and walk you through it before we start coding.
My understanding of early jet planes and test pilots suggests that they were iterating jets through ejections and near-crash experiences. :-)
In the 1950s, test pilots were being killed at the rate of about one a week[1]

tl; dr: I think Waterfall vs. Agile religious war is wrong; it's mostly about that you can't hit a moving target without a feedback loop.
That's why I don't think the discussion should really be Waterfall vs. Agile, it should be about feedback loops in the process. There are circumstances in e.g. military or medical projects where you absolutely, positively, need to work to an approved spec with time & budget analysis, etc.; it seems to be common outside of software (I don't see much of agile-built bridges or jetplanes). There are those parts of the process that can be predicted (and have their cost estimated) relatively well - those you plan in advance (aka. waterfall). There are others, where you only have a somewhat vague and changing final goal - there your only real solution is a process with a tight feedback loop (aka. agile).
Now you can look at software process on different levels - what might look like waterfall from the high level may be in fact a collection of very agile sub-processes. Which may contain waterfally sub-levels (like, isn't a single iteration of TDD red-green-refactor cycle a bit waterfally? ;). So I think instead of thinking about "agile vs. waterfall" we should consider what feedback loops we need where, and how tight they should be.

The definition of waterfall is that there is no loop. When one step is done, it's done.
Agreed. Waterfall is usually better when you do client projects. Agile would be better when you do your own product, at the same time Agile may lead to cost overrun.

Maybe they aren't aware of Waterfall. Pete Campbell on Mad Men had a great quote; "You know what? I have good ideas. In fact, I used to carry around a notebook and a pen, just to keep track. Direct marketing? I thought of that. It turned out it already existed, but I arrived at it independently."
If they are such experts, how would they not be aware of waterfall? Either they are idiots who have no clue about software development methodology, or they are just lying (either to their customers or themselves). It's not like it's hard to find a reference to waterfall if you bother to look.
The site looks nice. Whether or not their methods are the best, I've worked for quite a few folks who would find their presentation very appealing. Because they've been burned by companies who wrote code for them that didn't meet their expectations, they're excited about a company that will actually listen to their expectations thoroughly before the process begins.
We've invented the mobile un-friendly site! We are industry pioneers!

In an ideal world, Waterfall will lead to a worse product than an iterative one. We don't live in the real world, and I expect these guys deal with clients who regularly fall into the -from-hell[1] category. I would bet that many people posting here aren't running consultancies and don't have experience with such clients (or any clients).
In such a situation, it is in fact entirely rational to develop a lightweight, low cost UI that a non-technical person can commit to, i.e. sign a contract. The developer can then go off and implement it with a very clear legal case if the client then chooses not to pay because "its not what we wanted".
Its not what I do, and I know that many here take a more involved approach to their clients, but its undeniable that it is a successful business model, and in some cases I believe it can produce some result where otherwise there might be none. Equally I'm sure it produces results that are ultimately not used, but where the company still gets paid.

Doesn't look as terrible as "true" waterfall, but I think this is just marketing fluff to win people over by telling them about your rock-solid practices.
If they have an arrow that looped from Beta Testing back into Interface Design/Usability/Engineering/Coding, you'd probably end up with what most shops do anyways, speaking in broad strokes.

My founding business partner Ryan McMinn spoke at an open source conference in Toronto a few years ago. In the talk he explained how and why we built Unspace the way that we did.
http://www.youtube.com/watch?v=lIQIZ0NIkxk
He talks extensively about the need to work directly with the end users of the system, instead of the management. The realization that specifications are usually nothing more than mutually assured destruction.
Pretty much the only thing that's changed in five years is that the scale of our company has grown, and now we do indeed have contracts with our clients to protect us from bad things.
Anyhow, I highly recommend the video if you're looking for an in-the-trenches perspective.

I actually know Clark Valberg, the founder of Epicenter Consulting, and did some work with him a few years back; he's a great guy. You guys can criticize him all you want, but he actually cares.
We should direct our efforts towards the bloodsuckers, not the people giving blood.
We should direct our efforts towards the bloodsuckers, not the people giving blood.
We you say "he cares" I presume you mean "cares about slick marketing to clueless clients". Because Epicenter obviously doesn't give a damn about either the truth or software engineering.
I'm sorry, but the people who claim the one true method is keeping the programmers locked in the basement without real world input or feedback are the bloodsuckers.

No, I mean that he cares about giving his clients a great product. He's not just in it to soak money out of people; he actually cares about the outcome, much like an artist cares about their paintings.
And look, I'm not Clark. I don't speak for Clark. This is just the experience I had working with him and getting to know him for a year and a half.
And look, I'm not Clark. I don't speak for Clark. This is just the experience I had working with him and getting to know him for a year and a half.
I can ditto this. I've known Clark for years. He is an honorable person, as is his coworker Ben Nadel. Fault them if you will for 'inventing' something that already existed, but this was - at worst - an innocent mistake. How many people here have reached out to them to try to help correct their mistake?
I love how each coder has a giant clock right in front of their face.
How do you do usability testing without the real software having been written?
I never realized just how insane waterfall is until I saw this diagram. Wow.

I've got a bone to pick with people that have a bone to pick with waterfall, especially when they don't realize that whatever competing newer workflow they swear by is actually waterfall in disguise.
Let's just ignore for a second that a waterfall process sent men to the moon and continues to build skyscrapers, with each project having a set of stakeholders the size of a small city and all while adjusting to a shifting landscape of nearly infinite variables. Especially the first few moon missions, when no one had done it before. It's why all of the original astronauts were test pilots - not just because of their bravado but also their experience in co-designing unfinished machines along with the engineers to bring it to a workable finished state. The roots of the modern HCI and human factors industries comes from analyzing and optimizing the usability of cockpits. The astronauts even had their own usability jokes about a model of training jet that was so user-unfriendly that the emergency instructions for ejection were printed on the side of the canopy, which is nuts because step one was to blow the canopy (along with the rest of the instructions) up off into the sky.
These weren't dumb monkeys strapped to a giant tin can and blown into space, and neither were the engineers that sent them there. With waterfall.
So you use agile/xp/scrum/whatever and swear software is way different than building bridges. I've worked on and with several of those teams, with varying levels of strictness, and guess what? It's still basically waterfall. But instead of PMs owning the process and spec'ing things out in advance, engineers own the process and the spec is written and re-written during development on a bunch of index cards with sharpies like a grade school art project (or the digital equivalent), designers get barely a week ahead of each sprint or run around like caffeinated janitors cleaning up after each sprint, and documentation gets written last or not at all.
And before anyone does ad hominem attacks on whether my teams were doing agile correctly, this is the same dynamic I witnessed at the most famous agile and rails development shop you can think of. You probably only need one guess to figure out who it is.
What matters then, if it's not process? It's called expertise - a broad collection of various techniques and the context-specific awareness of when to use each one. Instead of blindly following a process and trying to hammer it into every situation, take a tools-instead-of-rules approach to using whatever techniques are appropriate for each project.
For anyone interested in this kind of flexible thinking instead of linear GTD productivity tools that leave you stuck in robot mode, there's an excellent book called Pragmatic Thinking And Learning that goes into a lot more detail and pulls inspiration from how the nursing industry overhauled their education system in the 70's.

I'm totally not getting why you're saying agile approaches are waterfall in disguise.
The essential difference to me is in length of feedback loops. Microsoft releases a new OS every few years; some place like Etsy releases new code many times a day. A developer or product manager at Etsy can know within a few hours whether some change is really a good idea; Microsoft not so much.
You seem to be saying that because there are the same sorts of people involved, and because one has a giant spec document while another has a stack of index cards that might be called a spec, then they're the same. Which isn't making any sense to me.

Nope, it has nothing to do with the commonalities in people or roles, sorry I wasn't clear. Let me try again.
It's a knock on all rigid processes and dogma, not agile in particular. I trimmed the rant down by taking out the sections that rip into UX firms, with their Big Upfront Design and cocky rockstar designer personas, but it could just as easily been about them. I only cut it because I thought the parallels were obvious with the diagram on the Epic Consulting website.
What I'm saying is that if waterfall means people are grouped together by specialty - programmers with programmers, designers with designers - each group is run by one dominant process suited to only one of the specializations, and each group tends to work in different stages, then both traditional UX design and agile development are run as de facto waterfall teams, whether by explicit hierarchies or simple stakeholder buy-in.
Consider this - what's the difference between:
1) a PM spec'ing things out in advance and basically telling everybody what to do and in which order.
2) an agile shop coding things up on the fly and telling the designers to run after them to clean up the visuals without making major changes, so they might as well be building to a spec.
3) a UX firm mapping out how the product works before handing off to peon engineers that can't make major changes and might as well be building to a spec.
To end on a positive note, there is one other solution to expertise, by the way. It's grouping teams by product, not role, and figuring out an interdisciplinary way to work together, rather than running the entire team by the methodology of one specialty. That way you're picking good ideas from across different processes and adapting to the company culture to boot. For example, TypeKit does daily stand ups at 10:05am every day and that's an aspect of agile that they've liked enough to use for the whole company, but I'd be surprised if their designers were checking their art assets into Pivotal Tracker or the programmers were writing up UX journey maps of each user persona.
Steve Jobs always liked to describe Apple as the biggest startup he knew and a more accurate description would be that it's a collection of startups, with each one focused on a single product. Seems to work pretty well for them.

This is the paper that was the basis of Scrum: The New New Product Development Game, Harvard Business Review, 1986. [1].
The crux of the paper is that you should be "grouping teams by product, not role, and figuring out an interdisciplinary way to work together, rather than running the entire team by the methodology of one specialty".
If the word "Agile" freaks you out, then by all means don't call it that. And certainly there are a lot of bullshit artists plying their trade out there. Indeed, if someone tells me they are "Agile", by default I don't believe them. But as this 1986 paper shows, there is a lot of good data and good theory out there if you but look.

Yep! I get it now. Thanks for clarifying.
I agree that "agile" teams that group people by specialty are clueless. Done right, the teams are, as you suggest, cross-functional. That was the original intent for the people who coined the term Agile, but much of that has fallen by the wayside as larger organizations decided Agile was fashionable and consultants rushed in to sell them 3% dilutions of XP or Scrum.
I've written more about how that happened here, and a lot of the early Agile types I've talked to agree: http://agilefocus.com/2011/02/21/agiles-second-chasm-and-how...

That's a great writeup! I know exactly how you feel except my disappointment was doubled, because I was a hybrid developer/designer for years before completing the switch from developer to designer and I lost the faith in both agile and UX at about the same time.
I wish I had the courage to write up my disappointment like you did, but I'm happy that I've moved on to a meta-process of borrowing from different techniques as needed.

Agilistas like to pretend that if you're doing waterfall you can't ever go back to the previous step.
Whereas in practice, if you find something wrong or confusing with the specification, you just hunt down the business analysts and ask them what drugs they were on when they pooped out the spec. And then after walking them through their mistake, you get a new and better spec.
If you do it often enough, they will start to catch on and actually do their job better. Don't think of that as a poke at BA's either, everybody puts more effort in if they know that someone gives a crap about what they do. They may not like it at first, but you're actually empowering them.

"Agilistas like to pretend that if you're doing waterfall you can't ever go back to the previous step."
The Agilistas are correct.
The reason for this is that Waterfall was constructed deliberately as a strawman. The very point of constructing Waterfall was to draw a distinction between the process as it was being presented to the VP, or in this case as it is presented to the customer, and the fact that in practice it doesn't work at all and therefore it could not have been what actually happened. Therefore, given that it isn't a possible process anyhow, we should embrace an iterative approach, because ultimately there's no alternative. We should face up to the truth and thereby learn to take proper advantage of it, instead of sneaking it in the back door, hiding it in shame, and deliberately doing stupid things that can't work because management thinks it makes them happy. And in this case, there's no possible way that that is an accurate description of what happens in any significant project that company undertakes.
If you don't understand that Waterfall is not and never was a "real" methodology and don't grasp the history, which it seems still almost nobody does, then you don't really get what's going on. And attempting to rehabilitate Waterfall into a real or viable methodology is metacontrarianism [1] run amok. There's no point in performing CPR on a scarecrow.

I thought waterfall was a strawman too, until I read The Checklist Manifesto and started learning more about other industries.
For example, large-scale construction projects like skyscrapers are run by gantt charts and committees, which sounds unbelievable and like a disaster waiting to happen. It's like the opposite of every startup I've worked at in the last 4 years. Except it actually works and they keep the everything running smoothly through:
* (at the top level) real time adjustments to huge room-filling charts that shown all the dependencies.
* (at the grunt level in the trenches) an abundant use of checklists to keep work mistake-free and to avoid groups stepping on each other.
* (at all levels) constant and real time communication. Lots of it.
So yeah, I think it's hard to write off waterfall as both ineffective and non-existent if a large industry uses it to such a degree.

Large-scale construction projects are also notorious for delays and cost overruns, so I wouldn't make too much of that.
Even granting your point, though, that doesn't tell us much about software. Nobody expects to start a building as a small house and work it up to something the size of the Pentagon. You can't automatically replace every screw in a building in minutes. Buildings aren't made out of words, and they don't have requirements that change continuously. Buildings aren't expected to respond quickly to competitor's new amenities. The construction of buildings is not 100% automatable with modern technology. So I wouldn't be too hasty in suggesting that the Waterfall approach is made more plausible by a similar-sounding process being used in an entirely different industry.
And honestly, real buildings aren't even much like what you're imagining. Stewart Brand's book "How Buildings Learn" examines actual buildings and how they adapt and change in ways very different than what people with GANTT charts think should happen.

Waterfall has no such history in the software domain. Analogizing software to construction has a long and worthless history, and it has failed to produce one actionable insight that I'm aware of. (It has produced some really dangerous pronouncements about how software engineering should be done, of the kind that you can crash and wreck a company on, though, so there's that.)
The problem is that construction has a completely, radically different cost model than software. If they could possible throw up one building today, tweak it, and throw up another tomorrow, they'd go iterative too. Instead, they have horrifying implementation costs that have no analogy to software; if Waterfall "works" for them it is only because they have no other choices. That's hardly a ringing endorsement, as wpietri observes.

Interesting outlook on things... I've always thought (and argued when possible) that the key to any software/computer issue is smart people - not 'rockstars' and these developers who think they're the center of the universe, but a team of capable people, familiar with a broad range of technology and capable of solving problems, using whatever tools are needed.
But I have long thought that waterfall just couldn't work - but I suppose it could if you have management and executives that understand the 'product' at the end will be iterated.
I have also been meaning to pick up that book...

Back when the competing methodologies were waterfall and RAD they used to say that 50% of all software projects failed.
When Agile became super popular they started saying that 70% of all software projects failed.
Hmmm....

I agree with you that any kind of process sucks when a team doesn't really know what they are doing.
And by using a methodology you are saying just that "we have no fucking clue, so we will try it this way that person X sol us".
I have debated agile proponents about whether agile would work in their respective organizations on multiple occasions. Usually I argue it would fail just as much as any other approach?
Why? Because people try to adhere to it strictly and completely miss or ignore their current context, which is usually THE problem they are trying to solve in the first place.
And you are dead wrong about waterfall. Waterfall is not even a methodology. Anyone selling himself as an "methodology expert" while trying to sell you on "waterfall methodology" is a quack and a fraud. Anyone talking about waterfall as a possible methodology is a quack and a fraud who knows nothing about methodologies. Because waterfall is not a methodology, just like adding rat poison to kids candy is not a business model. Waterfall has always, since the very beginning of the term, been an anti pattern a "anti-methodology".

Hilarious.
But all jokes aside, have you ever tried to explain to a self-described 'technical-enough-to-be-dangerous' corporate middle manager what an iterative and incremental process is?

I thought the most bothersome thing on the entire page was the claim they put "business over code". Without working software you don't have a business.
The sad part is, that most of their clients are probably buying into this and think what an excellent and innovative company they hired.
Ok, I just invented a new methodology, I dub thee: "Agilefall"
First we meet and discuss the goals for the sprint. Then I design (usually some class diagrams on a sheet of paper or board), then I code and test it (unit tests of course) and finally check it in. Each 4 to 6 week sprint is internally structured as a waterfall. :)

Is this a joke?
I honestly thought it was, but crawling the rest of the site it doesn't have an ounce of parody about it. I think these guys really think this is a new methodology...
For example, link to their "Chief Software Architect" linkedin profile: http://www.linkedin.com/profile/view?id=1613224
Dude has a six year gap in his resume where he goes from being a web designer to chief architect? That might explain why he thinks waterfall is new.
All of his (their?) work appears to be small-scale websites for small companies -- it doesn't look like he's built anything really substantial.

Some of these comments are missing the point. Their methodology isn't about how to build but on what to build. It's a problem many industries face. When the client is a non-technical person (the norm in making web apps) building the UI first makes good sense.
I agree. Most of the comments are overlooked. I suspect that the OP is competitor to the said company?
Epicenter is sending out some annoyed tweets while defending the AgileUX movement. They claim their process is nothing like waterfall as it focuses on iterative UX prototyping.

What I love best is this testimonial praising the book:
> Helms and Valberg lay out an innovative methodology that finally delivers on the promise of Agile Development.

The problem with both waterfall and agile is that we are missing the definition of "the Humble process" to develop software.
Unfortunately humility does not sell so well.

I love the fact that the software engineers basically deliver UML diagrams to the coders. I'd shoot myself if that were all there was to my job.
Thank you @JoshSusser for finding this diamond in the rough. What would we do without waterfall development!?

Would this help design a process to Balance the US gov budget?

So here's what you should do. Over the shoulder review of a representative employee of each department. HR, AP, AR etc. Actively watch and understand the processes they go through. FOR AN ENTIRE 8 HOUR SHIFT.
No, seriously.
Now, you've got a good idea of how its done current.
Then do the stake holder interview to find out what they want to do differently.
Then plan, develop and deploy your software.
I seriously don't get why despite there being a recognized need for understanding the problem scope which everyone one will invest hours in meetings and conference calls talking about, no one actually invests any (significant) time doing, or reviewing the actual process. It's the fastest most efficient way to understand the problem. It would totally diminish months of back and forth "here's what you asked for" "no, that's not what I asked for" development review process that almost _always_ occurs with consultant projects.
