| 2.2.5-10-1 Ensure clear method for designing operationally realistic LYF tests and identifying associated LYF test exceptions are documented for the appropriate level of the pyramid |
Phase C |
Phase D1 |
|
The LYF test design needs to be documented in work products including all design decisions for a LYF test, including test objectives, final test cases, initial / transition / end conditions, additional resources, test methodology and mission characteristics. Wherever LYF tests deviate from the characteristics of mission operations, these exceptions and their rationales must be tracked and considered in risk assessments. The objectives, architecture, plans , procedures, results and post-test analysis of each LYF test need to be documented. There needs to be a process that determines the best level of integration for each LYF test objective. This process must be able to include subcontractor levels. Tests should be identified for all critical mission phases, phase transitions, fault management situations, and planned contingencies. Identification should address suitable duration of each test to demonstrate executability and dependability. The three Pyramids - supplier, integration, and mission, should be addressed in the planning. (Note: this applies to re-testing as well)

| 2.2.5-10-2 Ensure there is a clear description of allocated test resources used for operationally realistic LYF tests |
Phase D1 |
|
Ensure Test resources are clearly defined, verified, validated, and fidelity between operational system and resource is specified. Test equipment, models and simulations used in LYF tests must be of sufficient fidelity to provide confidence in the test results. In addition, any support resources must be certified to the level needed. Any deviations in fidelity that would affect the detection of a fault must be documented in the test exceptions.
