Predict Future Process Capabilities
Lockheed Martin Electronics & Missiles successfully applies requirements management through closely-related initiatives. Obsolescence Management combines manufacturer information and technology assessments with various tools to predict when components and products will become obsolete. Commercial Technology Insertion addresses replacing military-specified parts with commercial products, obsolete units as well as new designs.
Obsolescence Management provides risk information on electronic component technologies to help designers determine whether the components they select will meet the life cycle development and cost-of-ownership requirements of the design. Obsolescence Management uses the Document Information and Control System for displaying on-line data. This on-line obsolescence information helps the engineer select current technology for product designs and also provides source data used by procurement and product assurance personnel. The system also furnishes descriptive data for standardization, parts control, and part status.
In the second initiative, Lockheed Martin is focusing Commercial Technology Insertion's initial effort on microcircuits. A commercial component is any non-military part, ceramic or plastic, including telecommunication, computer, medical, automotive, industrial grade, or other devices. The Commercial Technology Insertion program provides a comprehensive plan for the selection, application, and procurement of reliable, low-cost commercial components. Current emphasis is on replacing ceramic components with plastic. Moisture-induced and temperature cycling failures are two major long-term reliability considerations for plastic components. These considerations are being analyzed against various product requirements. Potential cost saving opportunities and return on investments for plastic over ceramic components can exceed a 75 to 1 ratio.
