It’s been several years since I worked there but if I remember correctly it was a little more complicated because these were basically subcontracts under one larger contract. The company had a huge contract agreeing to purchase some volume of services from the consulting company. For each project a smaller contract would be created to define the terms of the project and the resources would be drawn from the parent contract’s pool of purchased resources.

This created a lot of internal pressure to use contract resources as much as possible.
