"...most firms can't utilize the contract style employee because their own processes are so broken, their projects so tightly coupled and intertwined and undocumented, that they can't imagine how to separate something out."

I frequently find it frustrating that an employer can have meetings and make specific plans for a rented person doing a one time project, but they generally don't know how to organize or make their own people more effective. It's like the employees are a given, but this outside thing needs special approval and funding so it needs to be handled well.
