Unformatted text preview: ering specialties may vary on NASA projects by virtue of their diverse nature, some are always needed. It is the system engineer's job to identify the particular engineering specialities needed for his/her tailored Product Development Team (PDT). The selected organizational approach to integrating the engineering specialities into the systems engineering process and the technical effort to be made should be summarized in the SEMP (Part III). Depending on the nature and scope of the project, the technical effort may also need more detailed documentation in the form of individual specialty engineering program plans. As part of the technical effort, specialty engineers often perform tasks that are common across disciplines. Foremost, they apply specialized analytical techniques to create information needed by the project manager and system engineer. They also help define and write system requirements in their areas of expertise, and they review data packages, engineering change requests (ECRs), test results, and documentation for major project reviews. The project manager and/or system engineer need to ensure that the information and products so generated add value to the project commensurate with their cost. The specialty engineering technical effort should also be well integrated both in time and content, not separate organizations and disciplines operating in near isolation (i.e., more like a basketball team, rather than a golf foursome). This means, as an example, that the reliability engineer's FMECA (or equivalent analysis) results are passed at the right time to the maintainability engineer, whose maintenance analysis is subsequently incorporated into the logistics support analysis (LSA). LSA results, in turn, are passed to the project-level system engineer in time to be combined with other cost and effectiveness data for a major trade study. Concurrently, the reliability engineer's FMECA results are also passed to the risk manager to incorporate critical items into the Critical Items List (CIL) when deemed necessary, and to alert the PDT to develop appropriate design or operations mitigation strategies.
