------_=_NextPart_001_01C2BBA7.CB5E90A0 Content-Type: text/plain; charset="ISO-8859-1" I am only aware of the Barry Boehm TRW reports on factors influencing software engineering (I don't believe the process makes that much of a difference, the key enabler was getting the best people which could change your producivity by 400%) and some reports that appeared in IEEE Software a very long time ago, and if I remember well (which I doubt ;-) ) process and methodology had an influence of maximum 40%, again coming to the conclusion that the influence of getting the right people is much more important than anything else. This doesn't mean to me that process and methodology are not important as enablers, they probably are, but getting the best out of the people you have is perhaps more important and should come first. Motivated people don't seem to fail ... that was another statement made in another IEEE article once. I don't know the context exactly but in an interview someone said "We succeeded because we didn't know how to fail." or something along those lines. I see changes in process and methodology more as enablers to motivate people than really making a difference. Having some kind of a process/approach that all participants can believe in and share seems to be more important to me than whatever this process is. I see very little differences between different processes anyway. When referring to XP I see one big difference which is pair programming but I think a process emphasising inspections and reviews can achieve the same, perhaps better, results. Also the test first design is quite interesting but I think the value of testing is over-estimated (and that coming from a man who's heart and soul is in software testing). Economic models of IT investment are also interesting. What was the productivity gain measured from introducing office automation? Something along the lines of 1%?

There's a recent thread on the XP list about XP being taught at the university undergraduate level in the CS / IS curriculum. Is anyone aware of any courses in the Business schools (either undergrad or graduate) re: either comparing the economics of various approaches to software development or discussing economic models of IT investment within a business?
