i have a bit of a reputation for doing this, and a few personal relationships with business leaders who have tapped me for these kind of projects. in the end its kind of dysfunctional every time because various people in the org own the relevant responsibilties already and you are basically micromanaging them against their will as a prelude to termination or reorganization.

its not like the solutions are usually that hard to figure out, it's always a problem with people and their incentives ultimately.

the fixer role is basically to give confidence to the CEO that disempowering certain people is safe and there's a path out.
