I think that ID’ing and owning, defining and providing others clarity on one’s core values is really important. An organization can move forward, with its people on the same mission, when the central ideas are clear.
I don’t think “accountability” should be one of them.
Once your values and expected behaviors are articulated, then accountability comes into play.
Are you doing what you said you would?
That’s accountability – it’s an outcome, not a seed to be planted. It’s an expectation, but not a behavior in an of itself.
