This is what I call, development by a dozen managers. If you have every developer on the team on the look out to do The Right Thing then you be sure that you'll start replacing your decision-making strategies with whimsical fancy. A collective fiction, or methodology if you will, isn't supposed to replace individual thought with adherence to the all-powerful methodology. I'm suspicious of sales people with a vested interest in the methodology they're selling. A methodology isn't something you can purchase... the collective fiction metaphor is apt: you have to convince people to believe and adopt it. In my experience a team will adapt a methodology like Agile but the best teams will mold it to the way they do things. Their collective fiction needs to integrate their tribal knowledge, goals, experience, etc. There isn't Agile™ — there's Agile the X way.
