I think more people need to talk about best fit. People shoehorn scrum into every situation, when it is perfectly valid to say that it won’t work sometimes, and others when it would work well. You wouldn’t use JavaScript to build an operating system, and you wouldn’t write your browser code in C. So why assume that one SDLC regime is right for every situation. Scrum seems to work well when estimation really is possible and there is true ownership and flexibility on the team. I have not seen Scrum work well with brand new products or situations where practically every task is an unknown and the team is defining and prioritizing features in the product as they move and discover. Which makes sense as Scrum does assume a high degree of uniformity and definition. There are situations where the product owner, temporarily, has to be the whole team.
