1. Testability addresses the extent to which a
system or unit supports fault detection and fault isolation in a confident,
timely and cost-effective manner. The incorporation of adequate testability,
including built-in test (BIT), requires early end systematic management
attention to testability requirements, design and measurement.
2. This standard prescribes a uniform approach to
testability program planning, establishment of testability (including BIT)
requirements, testability analysis, prediction and evaluation, and
preparation of testability documentation. Included are:
| a. |
Testability program planning |
| b. |
Testability requirements |
| c. |
Testability design |
| d. |
Testability prediction |
| e. |
Testability demonstration |
| f. |
Testability data collection end
analysis |
| g. |
Documentation of testability
program |
| h. |
Testability
review. |
3. This standard also prescribes the integration of
these testability program requirements with other closely related,
interdisciplinary program requirements, such as design engineering,
maintainability and logistic support.
4. Three appendices are included to augment
the teslrsof this standard:
| a. |
Appendix
A provides guidance in the selection and application of
testability tasks.
|
| b. |
Appendix
B describes the Inherent Testability Assessment which provides a
measure of testability early in the design phase.
|
| c. |
Appendix
C provides a Glossary of terms used in this
standard. |
