MIL-STD-2106A(SH)
5.2.5 Redundancy analysis. Prior to preparation of test outlines, the list of test elements shall be reviewed to eliminate redundant testing within the stage for which documentation is being prepared. Each characteristic designated for testing at a given stage shall be analyzed to determine if the adequacy of that characteristic would be implicitly demonstrated by successful performance of a function designated for testing at that same stage. Characteristics meeting these criteria may be eliminated from further consideration as test elements. Interface test elements should be compared with the list of functions and characteristics designated for testing at the same stage. Interface test elements whose adequacy would be implicitly demonstrated by successful performance of a previously identified function or characteristic may be eliminated.
Elimination of all testing redundancies is not mandatory. On occasion, the added confidence gained through redundant testing outweighs the savings in reduced test time. This tradeoff requires the exercise of good judgment by the TDAs. When the redundancy analysis has been completed, the result shall be elimination of redundant test elements, wherever practical.
5.2.6 Test element grouping. The test elements that remain after completion of redundancy analysis shall be optimized for efficient test conduct by combining elements into test groups. These test element groups shall be converted to test outlines and subsequently to test procedures on a one-to-one basis; therefore, considerable care shall be exercised to group test elements in a manner that will produce maximum shipboard testing efficiency. The TDA shall consider similarities in the following areas as a guide to grouping test elements.
a. Test approach.
b. Inputs from other systems or services such as steam, cooling water, 60-Hertz power or 400-Hertz power. c. Computer programs.
d. Special support equipment and resources.
e. Other practical considerations identifiable at this point.
Examples of groupings include (1) all elements associated with gun loading; (2) all elements associated with initial checkout of a countermeasures receiver; (3) all elements associated with launcher hydraulics; and (4) all elements associated with initial start up of a diesel or gas turbine. This redundancy analysis will result in one or more groups of test elements which shall be the basis for preparation of test outlines. When specified (see 6.2), a list of
non-redundant test elements, which is the basis for proposed test outlines, shall be submitted prior to their
preparation.
5.2.7 Test outline preparation. A test outline shall be prepared as prescribed by Appendix B for each test element group identified in 5.2.6. The test outline may be used to:
a. Allow the test contracting agent to review the test development approach prior to test procedure completion b. Provide the industrial activity preliminary information for scheduling and manpower planning
c. Supply a description of test procedure content for all levels of management d. Provide preliminary bidding information
The information provided in the test outline shall be based on the best information available at this point in the development cycle and shall be supplemented by sound engineering judgment.
5.2.8 Test outline submittal. When specified (see 6.2), test outlines (see 5.2.7) and the list of related test elements (see 5.2.4.2) shall be submitted.
5.2.8.1 Master test plan submittal. When specified (see 6.2), test outlines (see 5.2.7) shall be combined into a
CDRL document and submitted in accordance with contract specifications.
5.2.9 Test procedure development. When specified (see 6.2), after submittal of a test outline, a stand-alone test procedure shall be developed from the test outline. The Test Number/Test Title will be part of the test procedure development process as described in Appendix A. The format and content of each test procedure shall be as prescribed in Appendix B.
Because the contents of all other test procedure sections depend to some degree on the testing steps, test procedure preparation shall begin with the development of the Testing Steps section.
