Level 3: Defined At this level, the roles and responsibilities of the process are defined and confirmed. At the previous level, we learned what needed to be done. At this level, we know who is responsible for doing it, and we have definitions of how to measure correctness.
I think the definitions of correctness (which metrics we want to gather and what values we strive for, before the metrics actually collected (automatically)) is probably a bigger deal than the assignment of responsibilities, but maybe it's always been more natural that the responsibilities are clear early on, even during chaotic phase?
