This is a change to the naming of the mapping/ framework. In the original version, one peak was "Peak Work Purpose" time has made it clear that this should be Peak Organisation Purpose.
The purpose of the body you work for, are paid by and gives you incentives.
Also, the bullets that go with the description have been updated to suggest this is where the majority thrive, essentially because of democracy and majority voting to bring in government and other political bodies. Where self-interests enable a majority to control the terms and policy. Shareholder primacy remains as a mistaken driver of corporate purpose but is a peak purpose because it is indoctrinated in management theory. Commercial growth is an idea for creating wealth which acts as a purpose and, lastly, shared belief because it brings in charities and other public sector work.
