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
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.
