> the most insulting thing was hearing a twisted version of the consultant's advice used as ammunition against the team, questioning its competence.

That's the advantage of having an expert that is no longer there. You can make him agree with whatever you want.

Once there was an expert invited to solve a problem at a company I worked for. Towards the end of his short visit, we met in a kitchen and talked for a while. I asked him what he thought about the problem we had, and he told me his opinion. After he left, there was a meeting where the managers told us what the expert thought. It was almost the opposite of what he told me. Was he telling different conclusions to different people? Or were the managers just lying? No way to find out, of course.
