Why Vista Release Date Really Slipped 562
anzev writes "A team manager for Windows for 5 years has decided to write a blog-essay about what caused Windows Vista project to miss the due date. Philip tells us in the blog, that Windows developers are writing an average of 5000 lines of code (which is *only* 1200 lines less than the national average of 6200 lines of code per year). He addresses issues like the Vista code being too complicated, the processes the developers have to follow too complex and a lot more. All in all it gives a nice insight into why Vista will be late, from a different perspective. Oh, and Slashdot gets mentioned too ;-)."

"Oooh, de poor little Vista Developers are sooo overworked. Lets give them a break."
No. Wrong. No break. And no extra auto-credit for being MS. I couldn't care less about Vista being delayed or not. But I will take every chance to turn the situation against all legends that cause people to think Computer == Windows. Usability == Doubleclick. Etc.
Reading that essay - from a Vista Guy with a position - gives of one clear message: Vista actually is a bloated weedy mess beyond any measure. And, guess what, making something new or not, the code that makes the unixes so usefull has been programmed allready and is in heavy field use for quite some time now. Somewhere between 10 and 20 years. After 30 years of unix, hardware finally is fast enough to run it on PDAs and cheap Notebooks. What x86 is to architecture - ancient, crazy, nutcase, but good enough for everything, even a Mac, Unix is to OSes - ancient, crazy, nutcase, but good enough for everything, even good enough for a Mac.
No, no break. Game over I say.
If MS has the guts to burn 10 Billion - 20 Billion on getting a new OS paradigm on to every plattform on the planet and do a good job at the same time they'll maybe make it. But even this late, jumping the OSS bandwagon and burning the cash it takes to take over the whole OSS service, distribution and customization sheebang would be cheaper and have better prospects.

This is my beef with Vista. It is late and when it ships, I expect it to be buggy with many follow-on Service Packs. The reason it is late and buggy is the absurd devotion to backwards compatability. I don't understand it. I could accept software compatability, but the hardware aspect is mystifying. Microsoft could spend five more years trying to get Vista to be all things to all people, but its stupid. OS X ships every 18-24 months. Granted this is not a full up new OS, but these releases are much more significant than service packs. I am of the mind that this is possible because they make the hard decisions about what hardware and legacy support should be cut. (Although it is easier for Apple, since they build the hardware too. Perhaps the saga of Vista shows that the Apple model is inherently more technically sound.)
Source for averages? (Score:5, Interesting)
I thought the number of finished lines of code per developer-day (that means debugged, documented, etc.) was only 20 for an average developer? A top developer will get closer to 10x that (mainly because when they write a lot of code in a day, they don't introduce lots of silly bugs that take a lot of time to correct later). Some developers actually have negative productivity overall (which makes sense when you consider the time spent by their colleagues to fix their bugs afterwards).
I can't remember where I saw those stats: probably something like Code Complete or The Mythical Man Month, I imagine, or possibly the IBM study into developer productivity at different ages (the one that says anyone under 25 is only good for documentation, and anyone 25-30 should only work on one project at once). Does anyone recognise the number?
I can't see any references in the blog post. Where do the figures of 6,200 (and the earlier 9,000) LOC/year come from?

It's perhaps worth mentioning that this was essentially IBM's approach back in the early days of "desktop" computers around 1980. There was this flock of little upstarts challenging IBM's growing stranglehold on the computer business by building small, cheap computers. IBM actually had a desktop computer, and it got very good reviews from its users. (What was it's 4-digit number? I've forgotten, but it was pretty good.
So they farmed the job out to one of those startups, run by Bill Gates and a few of his buddies, handed them a few hundred million for marketing, and didn't impose the IBM development rules on them. The result was crap compared to any of the CP/M desktops, but with a marketing budget greater than the operating budgets of all the upstarts combined, the result was what IBM wanted.
Microsoft has understood the lesson of this from the start, and put their money into marketing rather than quality product. Until now, maybe. If the reports of their growing development rules and costs are true, they may be going the way of IBM. They'll produce a good system for the first time in their history, but to avoid going bankrupt from the cost, they'll have to get a very good price for it, and only the wealthiest (and stupidest) will pay that price. If this is true, we're seeing a repeat of the IBM/Microsoft story from a quarter century ago.
Of course, IBM didn't die. In fact, they completed their conquest of the "mainframe" market, which was willing to buy IBM no matter what the cost. They completely own that field, and development has pretty much come to a halt. Due to MS's market clout, we could see the same outcome. They will own the "desktop", and further development in that market will grind to a halt. They'll still sell to the "MS at any cost" market. But it won't matter to most of us, because we'll more and more consider "desktop" computers relics of a previous age. We'll stop worrying about making new systems "compatible with the desktop" (i.e., clones of MS's systems), just as 25 years ago we stopped worrying about whether our little computers were IBM compatible (and we didn't bother with PL/I or JCL
So what should we call the new thing we're building while ignoring IBM and Microsoft? "Web 2.0" seems to be out (and wasn't very good anyway), but the new thing will certainly be Net-based. Any good suggestions for a name that will supercede "desktop"? Maybe we need a catchy two-syllable name for the software going into the OLPC project. Push for making it a truly distributed, comm-based system without any central control, so the comm companies and local governments can't take it over as they're doing with the Web. We can base it on zillions of small components, so a company that refuses to follow standards can't make any inroads. The "new paradigm" will be as outside Microsoft's world view as PC/DOS was outside IBM's world view.
C'mon, we need a catchy new name

You have answered youself: TFA asks if a project the size of Windows in controllable. In an environment where the tone is set by Steve Ballmer the answer sure looks like "No." Maybe "Hell no."
TFA also states Windows has 50 layers and circular dependencies. Linux has complex version and interface dependencies, too. But, evidently, the Windows dependencies are hairy enough to flummox 2000 smart people working in "concert" while Linux gets by with only a handful or people working in the same place at the same time and a much simpler process.
That is, Linux has better modularity and less process.
That points to the depth of the problem at Microsoft: They will have to change almost everything about how Windows is made in order to get a different result:
They have to stop telling developers to "do or die." Has that ever happened in the entire course of Linux development? Probably not. It's something that software project management can do without.
They have to get strong product management that knows which features are actually important, so you don't get that "do or die" message being sent to teams that are making things that don't add that much value.
They have to decouple development more: Why on Earth do you need to have 2000 people working in concert on any software project? That's a bug, not a feature.
They have to un-layer their management structure. 11 layers? That's ridiculous for a software company.
There is no one prescription for success. Apple succeeds by having very strong product management, so they know which features are actually important to the end user. Linux succeeds by having no product management at all, and having to adapt process to the practical constraints of being FOSS. Microsoft is stuck in the middle: Not enough product management strength to know which parts really deserve a "do or die" effort, and so much process, interdependency, and management layers that any of the 500 product managers Microsoft already employs that are smart enough to make these decisions can't possibly put them into effect.

About 7 years ago, I counted up that I had personally spent several thousand dollars on Microsoft products. I don't believe in pirating this stuff. Rather, when I thought about the kind of money I had been spending, and EXTRAPOLATED to what I'd spend in the future, I backtracked to the fact that I knew Linux pretty well, and I decided to make the switch. I've used Linux as my desktop as well as my servers since then. (And my first question to my local Mac-head was whether the new Mac's could triple boot OSX, Windows, and Linux.) I used Linux at work for years until my latest boss told me specifically that I couldn't run Linux. (I asked, if I was getting my job done, what it mattered. He didn't have much of an answer, but I let it drop.)
Since that time (Windows & Office 2000), the only money I given Microsoft has been the $15 co-pay for Windows XP that I got while attending the local college. At the time, I also got Office XP and MSDN Student Ed. for free. (Did I subsidize Microsoft with my tuition? Well, my employer did.) Yesterday, someone asked me to pirate a copy of Office for someone else, because that person didn't want to pay $400 to go buy a copy. I said no way. That's the whole point. Microsoft gets away with their practices because deals like the one with colleges, but that's a lot of money to a person who does volunteer work! That's the deal. It IS unfair. If you don't like it, then rightly be upset with Micrsoft's stranglehold on the market and do something about it. I told him to download OpenOffice and stick it on a CD for this other person. If 100% compatibility is worth hundreds of dollars to you, more power to you. But it's not to me, and I'm hoping that more people come to see it that way.

Good point. But there is a fundamental difference here. Things like the ISS, nuclear aircraft carriers, and whatnot have clear goals with very high standards in terms of functionality and quality.
Vista's "vision" (no pun intended) appears to be, lets add more crap to an OS and release it. Microsoft, if they are to stay a viable OS vendor needs to make a complete revamping of their system. Lets look at their history. First there was DOS. Wooptydoo. That was not much of an OS. They they slapped win 1-3x on top, and people still used DOS apps much of the time or at least a significant percentage of the time. The 1-3x GUI subsystem with the nastiness of DOS underneath was not very good, but it mostly worked. Then came the 9x line and NT separately. NT was a better OS. Multi-user, more "server" like capabilities, more stability (yet, not stable). Then the marriage between NT and 9x came, and they fought night and day
What is wrong with XP? The "Start" menu is a GUI designers worst nightmare. Too difficult to add, remove, or rearrange stuff in there. And now with XP, its like UNIX or Linux GUI stuff now. Every app looks and feels completely different. Some like to be MAXIMIZED, others are happy being windowless looking windows that simply float around on the desktop with every widget being different than every other apps widgets. Security/basic safety are nonexistent in XP. Yeah, they took that February off to get "security right", but that has failed the acid test. Windows GUI is completely obnoxious. Too much useless information being bombarded to the user. Balloon help all over the place. Tray programs yelling at you all the time. "Your desktop may have too many icons on it, but please don't delete the ones we don't want you to delete, OK?" Popup dialog boxes that steal the users focus, and are filled with information from "Nothing important just happened!" "OK" to things like "You may not have a nonworking anti-security subsystem that did not initialize." With the user then asked "OK" "Cancel" or the uber confusing "OK" "Apply" "Cancel". The OK/Apply/Cancel combination is the most confusing and stupid paradigm that STILL exists in Vista beta!
This is getting long, but its clear that Windows has problems. And going back to the ISS or nuclear aircraft carriers, software needs to be designed with a goal at hand, and a common set of means to achieve that desired goal. Gosh, this is almost like I'm trying to help out MS here, but they need to break down what Windows is supposed to do. Today in 2006, there is multi-media, media copying (CDs/DVDs), interaction between programs, presentation of programs, networking to include file/drive sharing, www, ftp, email, all that stuff. And of course there are the things that are fundamental to an OS that when done well, the user knows nothing about them. Things like hardware driver abstraction layer/subsystem, memory management, disk managemt, basic security, user separation. AND then after all of the basics are met with an intuitive an non-obnoxious interface, they, and only then do you add new and better performance and functionality. Things like a decent command line shell (monad does not seem to cut it). Things like a metadata filesystem and searching mechanism (WinFS is a decade into development).

I must say that the GNU/Linux camp must watch its step though. Too much reliance on KDE and/or Gnome can result in some of the same problems. Ok so the kernel will always be seperate, but what about all the utilities like sox, libjpeg, libxml, libwww, libtiff, etc? If these slowly start moving into the GUI, a slow moving(feature/upgrade/etc) desktop or worst an unstable and insecure desktop is still going to be bad for users. For many, a crashing GNU/Linux desktop is going to feel just like a crashing Windows OS/system. The movement toward compound document frameworks( openParts/etc ) could help here but there is definately a chance of the GNU/Linux desktopPC moving toward the same problems MS developers are seeing with Windows. Atleast to some extent.
But right now, the advantage is on the GNU/Linux and OSS side.

An architectural diagram of Windows would suggest there are more than 50 dependency layers (never mind that there also exist circular dependencies). After working in Windows for five years, you understand only, say, two of them.
If you have 50 dependency layers, wheras Linux or Mac OS X have something like 10 (in the most pessimal case, for things like desktop Widgets), you've probably been spending most of your time writing new ways of doing old things, over and over and over, and you do this cuz

TFA is sadly now removed by the author (does anyone have a copy in their browser cache?), but there is no evidence in it that Microsoft uses lines of code as any metric whatsoever.
