6.7 Producibility Producibility is a system characteristic
associated with the ease and economy with which a
completed design can be transformed (i.e., fabricated,
manufactured, or coded) into a hardware and/or
software realization. While major NASA systems tend to
be produced in small quantities, a particular producibility
feature can be critical to a system's cost-effectiveness,
as experience with the Shuttle's thermal tiles has shown.
6.7.1 Role of the Production Engineer The production engineer supports the systems
engineering process (as a part of the multi-disciplinary
PDT) through an active role in implementing specific
design features to enhance producibility, and by
performing the production engineering analyses needed
by the project. These tasks and analyses include:
• • •
portion of the system risk management program
(see Section 4.6). This is accomplished by
assessment and by planning effective risk
Identifying system design features that enhance
producibility. Efforts usually focus on design
simplification, fabrication tolerances, and
avoidance of hazardous materials.
Conducting producibility trade studies to
Assessing production feasibility within project
constraints. This may include assessing
production experience and capability, new
fabrication technology, special tooling, and
production personnel training requirements.
Identifying long-lead items and critical materials
Estimating production costs as a part of
life-cycle cost management
Developing production schedules
Developing approaches and plans to validate
fabrication/manufacturing processes. The results of these tasks and prod...
