Abstract

<strong>Description of Driving Event:</strong> <br>Requirements for the operational era was introduced into the system in early 1985. The foundation for the system, operations and maintenance requirements and specifications document, provides a sound base on which to build a mature system as future requirements are defined. Some problems have been encountered while progressing toward a mature system. Implementation of newly defined requirements is not always accomplished according to an agreed upon plan that can be supported by all involved functional areas. Level II also lacks an active closed loop audit system to check the quality of compliance with established requirements. Additionally, there is no baseline postflight turnaround schedule to use as a basis for tracking long-term trends in waivers, deferrals, additions, or deletions to the KSC flow.
