My experience of working with technical consultants was that they made things unnecessarily complicated. There were unnecessary meetings, and other unneccessary processes. The "main" job of a consultant was to find new business; for that, they got bonuses. For doing the job the client hired them for, they did not get bonuses. Unsurprisingly, jobs went on forever. There was no benefit to a consultancy firm in completing a contract; that would mean the end of the line for the gravy-train. So projects lasted years. This was a couple of decades ago; I hear less about technical consultancies these days, so perhaps the world has moved on. But I used to feel sorry for companies that had allowed a technical consultancy to get a foot in the door.
