A software team where everybody expresses their opinions loudly and strongly, always being ready to admit that "I was wrong," is not able to produce anything serious. This is what I read in one blog post recently. And I do agree with this. However, I disagree with the solution suggested in the blog post. The author suggests programmers be more humble and skeptical, which I believe will only lead to more compromises. We know that compromises are bad for quality. My solution is to have a formally assigned architect, who makes all final technical decisions.
