Oddly enough I've been on the other side of this:
Multiple IC's brought together in a meeting, to prepare for the meeting with the contractor, "to avoid wasting the contractor's expensive time." Writing and reviewing a statement of work for the contractor in excruciating detail, when an IC doing the same work would just figure out what was needed.
I made a mental note of what skills were so much more valuable than mine. Now I have those skills.
