It is interesting to see how people react to the rising of Agile Software Development methodology. In this video, it explain why PRINCE II by itself is complied to Agile Manifesto, though it conveniently forget to mention the 12 principles. The host also try to justify (by cherry picking some example from Scrum process framework and etc) on why PRINCE II has been Agile all the while.
What they are missing is, Agile is not about the process, it is about the mindset. You can definitely be Agile while using PRINCE II process framework, it is just that some process framework are more efficient and some introduce more waste. To be Agile, we would like to be more efficient by eliminating the waste.
The host pointed out the difference between Agile planning and PRINCE II planning, i.e. empirical planning in Agile and rational planning in PRINCE II. The host missed the point that the reason why Agile using empirical planning, is because they embrace the fact that changes is the only constant in life. Hence, investing heavily on detail planning upfront is very likely going to introduce a lot of waste.
The host also making commend such as the time-box duration can be longer, he was quoting example of 1 year duration. Here he missed out the point of the reason why shorter length time-box is being encouraged, it is to have early feedback. This is aim to eliminate the waste by having early confirmation on what is developed.
As a conclusion, I still think that PMI's approach to the "Agile Problem" is better. They had went through the stage of introducing iterative project management approach, to finally realize the incompatibility and introduce PMI-ACP.
