I did not expect this but I have noticed interesting side effects doing AGILE/SCRUM.
I already knew that AGILE/SCRUM killed projects and development at the pace of your worst develop in your team. But inside those teams the very people that hates it are also the most productive.
And it is very obvious, the people that hates it are people that are already good in AGILE. They hate SCRUM because it slows them down in developing things. They hate SCRUM because they force them to become unproductive.
And here is the very interesting thing: These people that hate SCRUM are so agile that they adapt to the crippling nature. they find ways to bypass crippling productivity and create new tools to cheat on SCRUM. They learn to cheat when you have have to estimate these crazy numbers. You try to guess what the other will show. They even learn to pretend that they are happy in these team events.
Evolution at its finest, natural selection in your developers. SCRUM probably burns out 90% of your developers in about 6-12 months but some will survive and become even better developers. But these fittest of developer escape your company every moment they can.
Currently I am in one of the most stable SCRUM teams I ever worked in. Very high end developers. Equals in my eyes. But it won't last.
