OK, then I understand your position better. This is hacker news after all. BTW, I think that there's misunderstanding between software developers and business people because software development is not as much about technology and hard facts as non-developers tend to think. It is very much about organization, people and processes. So in that way, software development is more similar to business than business people expect.
