A rationale and approach for defining and structuring testability requirements

Testability concepts and requirements are being applied to many Air Force electronic equipment/system development programs. Insufficient guidance exists as to the definition and structure of testability requirements and the interface between such requirements and maintainability, availability, and integrated diagnostics. The purpose of this report is to provide one logical approach and associated guidance to the definition and structure of testability needs and: (1) the relationship of testability to other system parameters; (2) the translation of testability needs to testability requirements; (3) the interpretation of testability terms, concepts and requirements; (4) the structure and scope of testability requirements; (5) and the identification of those factors, constraints and contingencies which must be considered when invoking testability requirements.
