They collectively agreed that only mandatory changes - i.e., changes for flight safety or to ensure mission success - could be made once the spacecraft reached KSC. (Changes that would speed the KSC checkout flow also were permitted.) Furthermore, two separate work packages would be prepared for each spacecraft customer acceptance readiness review board. The first package comprised normal work to be performed at KSC on all spacecraft. The second included special work normally done at the factory, but which for that specific vehicle was being transferred to the Cape (installation, retesting, etc.). The group also reviewed recent Apollo checkout experiences - especially test failures and open items - in an effort to improve these areas for subsequent missions.
