Testing fully testable systems: A case study

Testability is a measure of the potential to evaluate performance, determine operability, or identify faults within a system. Testability must be coupled with a strategy by which it is used to achieve field maintainability. It is often difficult to distinguish between shortcomings in testability and shortcomings in diagnostic strategy; however, adequate levels of both testability and diagnosis are required. An analysis of the Blackhawk helicopter illustrates the importance of matching the maintenance procedures to the maintenance architecture and the mission requirements.<
