McKinsey brought their wrecking ball through our company, they take a portion of the savings they introduce for their fees, so great incentive to cut, cut, cut. They were clueless as far as I could tell, Microsoft Copilot could have done it better. Really, the best people to dictate how you organise your departments is your own management team - outsiders can't offer better insights than you already have. If the board decide your management team are underperforming in structuring operations then they should change the management team, not pander to them with the idea that some external group can organise your business any better.
2 years of transition and then the re-hire program as soon as McKinsey left; what a ridiculous thing to put your company through!
Management team that brought McKinsey in still at the helm, ho-hum.
