TABLE OF CONTENTS The testability program for a system design effort must be integrated with other design and analysis tasks to achieve the goals of the design program. The goals of a testability program are shown at Figure 5-31. The first goal of the testability program is to support the maintainability program in the areas of meeting performance monitoring of the system and designing into the system the capability of testing for corrective maintenance actions at all levels of maintenance. Second, the testability program must provide a basis for the logistics support planning effort with regard to selection and use of support and test systems. The third goal of the testability program is support of and integration with the design engineering effort to meet testing requirements, including the hierarchical development of testability designs from the piece part to the total system.
Integration with system and design engineering to meet testability requirements
Support of and integration with maintainability design
Support of logistic support requirements planning
The first step in meeting the goals of a testability program are to determine the discrete testability requirements for the system being designed. The desired result is to determine the best alternative testability requirements for the new system when considering the effectiveness of the testing, the depth of testing required to support maintenance, and the cost tradeoffs of manual versus automatic testing. The development of test alternatives should consider the use of new technologies that enhance the testability of...
