This is the basic Plan Do Study Act loop that is used at multiple levels in an agile project.
At the lowest level it is the Red-Green-Refactor cycle of TDD
At the task level it’s the do we know enough to know what to do, report what is finished and update the next steps.
At the initiative level it’s the breaking down items into discrete tasks and ensuring that each incrementally adds value.
At the team level it’s the retro and the resulting actions to drive improvements.
