LengyelSubject: Space Shuttle Program/Operations-Processing/Workforce Description of Driving Event: Reduction of Government Mandatory Inspection Points (

2、GMIPs)Lesson(s) Learned: The reduction of Government Mandatory Inspection Points (GMIPs) at KSC has significantly lagged the downsizing of NASA quality personnel responsible for processing these GMIPs. This has resulted in an expanded workload among remaining NASA quality inspectors and made it more

3、 difficult to conduct analyses needed to identify further GMIP reductions. There has been a similar reduction of NASA safety inspectors and engineers at KSC without a commensurate reduction in over-sight requirements while, at the same time, the addition of new safety audit or insight responsibiliti

4、es has taken place.Recommendation(s): Any downsizing of personnel by both NASA and Shuttle Processing Contract (SPC) should be preceded by the reduction of commensurate workload associated with Space Shuttle processing, such as reduction of GMIPs and NASA safety inspections. Evidence of Recurrence C

5、ontrol Effectiveness: NASA concurs with the recommended approach of reducing the workload in Space Shuttle processing before proceeding with downsizing NASA and SPC personnel; however, we have not been as successful in this area as desired. In the downsizing effort implemented in February 1998, SPC

6、experienced an unexpectedly high level of voluntary attrition in certain critical functions-an outcome that was predicted by ASAP members and others. Although SPC experienced shortages of Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-critical skill

This was done by a combination of launch schedule relief, back-filling SPC shortages with

8、NASA expertise, and re-hiring technical expertise to train and certify SPC staff, thus eliminating shortages in critical skills. Evaluation of GMIPs for potential elimination by process engineering and quality engineering staff continues. It is estimated that approximately 6,000 of the original 22,0

9、00 GMIPs will remain in place at the end of this effort. This is a level assessed as commensurate with the current NASA quality inspection workforce. NASA Headquarters Office of Safety and Mission Assurance (OSMA) continues to evaluate the situation at KSC regarding NASA and SPC workforce reductions

10、 by assessing process efficiencies and workload indicators. Indicators of process effectiveness include overtime rates and first-time quality rates. Although the efforts are not yet complete, OSMA anticipates that as GMIPs are reduced overtime rates for NASA quality inspections will drop. Additional

11、ly, if the development of process efficiency initiatives by SPC are effective, then, when implemented, OSMA anticipates that SPC engineering and technician overtime rates will drop and first-time quality rates, based on NASA surveillance sampling, will increase.Documents Related to Lesson: N/AMissio
