describes the stages of learning to mastery.
In shu, we repeat the forms and discipline ourselves so that our bodies absorb the forms that our brain created. We remain faithful to the forms with no deviation.
Next, in the stage of ha, once we have disciplined ourselves to acquire the forms and movements, we make innovations. In this process the forms may be broken and discarded.
Finally, in ri, we completely depart from the forms, open the door to creative technique, and arrive in a place where we act in accordance with what our heart/mind desires, unhindered while not overstepping laws.
Learning Agile you also go though these phases and must respect the elements in the stage you are in and the stage the people you interact with is in before applying the agile mindset. There are many other maturity model (ex. Dreyfuss model) but this Shu-Ha-Ri is the simplest and Leonardo da Vinici said "Simplicity is the ultimate sophistication" so lets stick to this for the time being.
