1、Public Lessons Learned Entry: 5057 Lesson Info: Lesson Number: 5057 Submitting Organization: KSC Submitted by: Jenni Palmer Subject: Design Supportability Requirements Abstract: The Constellation Ground Systems requirements lacked design supportability requirements in its document set. To improve su

2、pportability, these requirements must be included in the development process. Therefore, ensure that design supportability requirements are in the Ground Systems Requirement documentation. Description of Driving Event: Ground Systems requirements documentation lacked Design Supportability Requiremen

3、ts. Lesson(s) Learned: To improve supportability and reduce support infrastructure and Life Cycle Costs, supportability performance requirements must be infused in the requirements development process. Lack of adequate supportability requirements can, and will, increase Life Cycle Costs, infrastruct

4、ure costs, decrease Verification & Validation effectiveness, and decrease the ability to measure system effectiveness. Recommendation(s): Ensure Design Supportability Requirements are in Ground Systems Requirements documentation and flowed down to influence system designs. This can be accomplished b

Supportability performance requirements such as useful service life, commonality/interchangeability, and RMA (Reliability, Maintainability, Availability) should be identified early for any future development program and included in
