The following part characteristics are considered critical and require additional attention due to potential reliability, manufacturability or availability problems.
Performance Limitations: due to stringent
Reliability Limitations: component/material swith life limitations, high defect rates, or the use of unrealistic derating requirements
Vendors: those with a past history of delivery, cost performance or reliability problems
Old technology: those with availability problems
New Technology: parts fabricated using immature design and manufacturing technology
The first three categories require historical data to track and define actions to minimize their occurrence or provide alternate solutions. The subject of old and new technology can involve the generation of different procurement procedures for tracking technology maturity, obsolescence and hidden hybrids (i.e., those devices that fall between generic device categories and, as a result, are often incorrectly specified and tested).
