I agree especially on the implementations front, when success or failure of a huge implementation project hinges on a single (or small team) of full-time employees, it's often better to just pay a premium to consultants to minimize the risk of a botched integration and have some written recourse, rather than firing an incompetent team and suffering the consequences of a botched project at the scale of a large company.
