I was a technical project management consultant for a long time. The value that most orgs get from a consultant isn't really in the advice the consultant gives them, it's the political cover to make changes they knew they should make all along, but didn't have the social capital or the focus to make those changes until they had a person in a chair across from them.
It's exactly this. Within any organization, you can have 3 or 6 important people pushing in completely different strategic directions. And it can be clear to any unbiased observer that there's only one good, responsible choice, but within your org that gets met with essentially "but that's just your opinion , man". So you call in a consulting firm and they deliver what most of the people already know. The consultants…
I remember one awkward situation i was familiar with where two diametrically opposed groups both notionally hired the same consultancy firm to write their respective proposals/submissions.
No points for guessing whether the consultancy offered the same advice...
Funny in one sense, but only because if you don't laugh you'll cry...
