I’ve just stumbled over an interesting blog entry: Why Agile is failing.
Cyrille shows in a very smart way the problems that I’m facing while selling our software to our customers. We are working internally according to Scrum (it’s actually ScrumBut, but anyhow), but our (enterprise) customers like to work on a strict waterfall model (for the process, not for their ideas :-)).
What is missing is an acceptance of the customers and a smooth migration strategy especially for enterprises to adopt agile methodologies (and not only for s/w development).
As long as this problem remains, there’s some kind of mixed mode where we try to handle two methodologies in parallel.
