1、Lessons Learned Entry: 1495Lesson Info:a71 Lesson Number: 1495a71 Lesson Date: 2003-07-01a71 Submitting Organization: MSFCa71 Submitted by: Donald DugalSubject: Next Generation Launch Technology (NGLT): Establish an Early Link Between Systems Engineering & Analysis and Technology Projects Abstract:
2、Initially, there was no strong link between the VSR&T Project and the SE&A projects. This link was needed to ensure that the proper architectures and, hence, technologies were being addressed. Without the proper linkage to SE&A, the VSR&T Project may not have been addressing the critical technology
3、requirements for the NGLT architectures under consideration. Systems engineering and analysis should be linked to the technology development projects early in the program. Description of Driving Event: Several technology development activities from 2nd Gen RLV and ASTP were combined to form the NGLT
4、 Vehicle Systems Research and Technology (VSR&T) Project. Initially, there was no strong link between the VSR&T Project and the SE&A projects. This link was needed to ensure that the proper architectures and, hence, technologies were being addressed. Without the proper linkage to SE&A, the VSR&T Pro
5、ject may not have been addressing the critical technology requirements for the NGLT architectures under consideration. Later, the System Analysis Project (SAP) attempted to remedy the situation by interacting with the various NASA Centers conducting technology development. An Architectural Design an
6、d Technology Initialization Workshop was also held to bring together the various systems analysts and technology developers for NGLT, albeit after the fact.Lesson(s) Learned: A strong linkage between systems analysis and technology development is needed from the start of the program.Recommendation(s
7、): Provided by IHSNot for Resale-,-,-Systems engineering and analysis should be linked to the technology development projects early in the program. Systems analysis should be used to develop quantifiable priorities and requirements against which technology projects should execute. The systems analys
8、is activity should actively engage technology developers throughout the life cycle in developing requirements (working with hardware developers - e.g. utilizing the “Value Stream” process), ensuring models are valid, assessing the progress of the project, and ensuring the continued relevance of the
9、investment against other, competing priorities.
