Spot On
After many years of trying everything on the market I can state the following:
Agile like Communism is a very nice theory... nothing more!
In practice, a very small number of projects are gaining by applying Agile instead Traditional management and those projects would have been just fine managed by a Project Manager instead of the 'self-managed team'.
The only method working so far, only because is addressing the core issues of a company is Fast-adapt, which so far has not reached the Mainstream.
When a certification in a method is around £1500 I doubt if there is more gain in using it or in selling it?
