Working with expertise as momentum for change
Using a variety of Skeleton-Keys makes the cooperation within teams and people more likely due to the fact that you are working along using their expertise as the momentum of change.
Change through a small nudge
Using the current environment and resources as good enough (because the team / person created and works that environment) respects the interactive nature of work and may bring change about through a small nudge as opposed to a prescriptive yank.
Accountability and authority cannot exist in equilibrium
The notion that a team can define accountability & authority means that they know the outcome before it happens & have removed all ambiguity, judgment, innovation & human interaction from the work. That to me sounds like a robot path to disengagement.
