Yup, that was my thought as well, though of course I didn’t dig as deep as you did. Many of us have been there. Especially when you are in software. The project is late, but the heavy lifting is done. The spec is written. Half is implemented. Then someone from management shows up, and gets in a contractor to “help”. Now you spend half your time getting the %*&$ contractor up to speed, so that he can tell you how things should be done (the process), while you’re already at a point that any new recommendations is only going to make the project later.
The bringing in of the contractor/advisor, even if well intentioned, is already a bit of an insult. It implies you are incompetent.
