1、Lessons Learned Entry: 1497Lesson Info:a71 Lesson Number: 1497a71 Lesson Date: 2003-07-01a71 Submitting Organization: MSFCa71 Submitted by: Lisa CarrSubject: Orbital Space Plane/Development and Planning Documentation Abstract: The Orbital Space Plane (OSP) lacked development and planning documents.
2、These documents may have aided the program in proceeding to the next level. Description of Driving Event: OSP planning documents were not sufficiently mature when the decision was made to embark on an accelerated program.Lesson(s) Learned: OSP planning documents were not sufficiently mature when the
3、 decision was made to embark on an accelerated program. Parallel development during program execution deadened the sense of urgency to complete them. Absent these documents, unseen organizational friction and implementation inefficiencies resulted. Additionally: a. Program Plan and SEMP The OSP Prog

Schedule Planning and Implementation A lack of standardization of inputs from various centers and organizations complicated the Integrated Master Schedule baseline and updates. Additionally, in response to acceleration of the program, two separate sched

Flight Test Planning Flight test has a major impact on technical, schedule, and budget planning and should be considered in up-front planning.
7、Schedules leading to verification by flight testing need to be assessed for credibility. d. Program Shutdown The OSP program ceased abruptly. Some key players were reassigned early, including both managers and administrative personnel thus further complicating the shutdown task. Geographically dista
8、nt centers relied on web-sites and electronic meeting notices and calendars but, these tools were not updated regularly and then shutdown prior to programs end. Recommendation(s): It is a mistake to proceed with a program without at least a fully developed, documented, and communicated Program Plan
