The objective of maintainability evaluation is to
evaluate the impact of the actual operational, maintenance, and support
environment on the maintainability parameters of the system, to evaluate the
correction of any deficiencies exhibited during maintainability demonstration,
and to demonstrate depot level maintenance tasks when applicable. A
maintainability evaluation is managed and conducted by the procuring activity
during Operational Test and Evaluation as part of the total system evaluation
(see Figure B-1 ). Many of the requirements for demonstration testing apply for evaluation testing except for the following:
- All evaluation items are production or production equivalent models
- The evaluation is conducted in the actual operational and maintenance environment unless otherwise specified by the procuring activity
- All maintenance tasks are performed by those personnel (either procuring agency (e.g., government or civil service) or contractor who would normally perform maintenance on the system in the fielded environment at the specified maintenance level.
- Maintenance tasks to be evaluated are those resulting directly from and incidental to actual operation and maintenance. These tasks should be supplemented by fault simulation only to evaluate specific tasks or special tasks that do not occur by chance during the evaluation phase.
