Each issue is evaluated for logistics impacts, and this information is communicated to or within the design center so that appropriate action can be taken to initiate any required redesigns, modifications, or enhancements.

While obsolescence will continue, a team approach to problem identification, prioritization, and resolution appears to be providing effective problem resolution. Additionally, the Shuttle upgrade program i
