Purpose gives you an overriding reason to do and act in certain ways, then using agile practices to respond to changes in the environment, I think you will be able to align quickly to the direction that you set. The commitment to the framework goals that you are trying to pursue, and the purpose driven approach helps you to do that as well. Agile is very people centred, it’s about giving people autonomy so that they can pursue the initiatives that you are trying to put in place. Agile is the ideal approach to execute change because it tends to make more committed employees and give them more of a reason to want to engage and develop the change programmes you are trying to pursue.
