I was responding to the fault-deflection in the previous comment. Sorry if that wasn't clear.

If its not exactly what NTS is then lets use some other phrase that better captures "Lets continue to apologize for the failure to implement the agile manifesto effectively in many situations". An effective business practice has to be able to be put into practice. Without a large potential-energy-hill of retraining and right-think and group buyin. I don't think agile is that thing. I'm sure some small groups have successfully done something they call agile (not yet convinced its by simply adhering to the manifesto), that's great for all who succeeded.

But the war stories of failure are pervasive.
