Software Engineering at Microsoft
an_mo writes "A link to a google cached document is floating around some mailing lists containing some info about microsoft software engineering. In particular the document contains juicy bits about the development of a large project like NT/2K. Some examples: Team size went from 200 (NT3.1) to 1400 (Win2k). Complete build of win2k time is 8hrs on 4way PIII and requires 50GB of hard drive space. Written/email permission required for checkins by the build team." The HTML version on Usenix's site is much nicer than Google's auto-translated version.
It seems that Microsoft does not use Visual Source Safe for Windows source code.
What's interesting is comparing what Showstopper says to the claims in these slides.
The slides suggest early NT development was done by a small team of super l33t c0d3rz who took care of business and frowned upon slacking. However, the picture painted by the book is dramatically different -- people were forced to work around the clock, the team was dominated by a small gang of guys who were basically complete assholes, everybody walked on eggshells for fear of pissing off Dave Cutler, The New Savior, and NOBODY in the group ever knew what was really going on. The whole project was shrouded in mystery, even to people on the team, because basically everything existed in Cutler's head.
The only thing I see where Showstopper and the slideshow firmly agrees is the slide labeled "Goal Setting".
I personally have a lot of other opinions about why some of the statistics may pan out the way they do (for example, how much hardware did you REALLY have to test with in NT 3.1 days, versus Win2K?) but I want to stay focused on the Showstopper/slideshow discrepancies, so I'll leave it at that.
The thing to realize about Showstopper is that it was based almost entirely on interviews with the people who were involved with the initial NT coding effort.
By comparison this slideshow was written by one guy, Mark Lucovsky, who gets lightly flamed in Showstopper (at best). Oddly, I grabbed Showstopper off my bookshelf and opened it straight to the page describing Lucovsky. Weird. Anyway, here are excerpts from a single paragraph: "...smart but immature... nevertheless angered teammates with his skepticism and self-serving judgements... relentlessly critical of others, constantly probing for weaknesses... 'Until you prove otherwise, you're wrong and he's right.'" Whew, hate to be THAT guy. It gets worse. One page later, a paragraph opens by simply saying, "Many people felt that Lucovsky was a jerk."
Given that, it wouldn't surprise me if Lucovsky was still just trying to justify the fact that the early NT dev team was comprised of a bunch of flakes who had to burn the candle at both ends to actually deliver anything.
Please understand I'm not necessarily defending any current MS practices, or even Win2K (which is still vastly superior to NT3.51). I've personally worked VERY closely with groups inside MS at different times (a couple times on-campus in Redmond), and I'll be the first to tell you the company is bureaucratic and packed to the gills with people who don't know what the hell they're doing -- just like every other company that employs tens of thousands of people.
What I *am* saying is that this slideshow is looking at the past with "rose-colored hindsight" and I believe the motives are suspect at best. Draw your conclusions with a grain of salt. (Enough metaphor-abuse for today.)
Do like johnjones suggested -- go buy or check-out Showstopper and read it. It's interesting, informative, and it IS kind of funny. It's amazing they were able to produce anything at all. How's THAT conclusion for contrast with the slideshow? ;)
