Management of maintainability verification/demonstration/evaluation should include the development of a maintainability test program plan8. The plan
is prepared by the system developer and should typically include the following
sections, tailored according to the specific requirements of a program. Each
of the sections should be in some way identified as being applicable to verification, demonstration or evaluation phases of the program.
Background Information - Includes a description of the quantitative and qualitative maintainability requirements; the maintenance concept; maintenance environment; applicable levels of maintenance; where testing is to be conducted; test facilities requirements; participating agencies; mode (s) of operation of the items of interest, including configuration and mission requirements; the specific items that are subject to verification, demonstration, and evaluation; and data required for completion of the verification/demonstration/evaluation.
Item Interface - A description of the adequacy or inadequacy of the item support elements and an estimate of their effect on the item maintainability. These elements would include the following: Maintenance planning; support and test equipment; supply support; transportation, handling and storage; technical data; facilities; and personnel and training.
Test Team - A test team should be assembled and described in the plan. The description should include: Organization, degree of participation of procuring activity personnel and system developer personnel, including managerial, technical, maintenance, and operation personnel. The plan should also include test team member qualifications, quantity, sources, training requirements, and indoctrination requirements.
Support Material - This section should cover support equipment, tools and test equipment, technical manuals to be used (or required), spares and consumables requirements/needs, safety equipment needs, and calibration equipment requirements.
Preparation Plan - Include a description of and schedule for the organization and assembly of the test team, training of personnel, preparation of facilities, and availability, assembly, checkout, and preliminary validation of support material.
Implementation - Provide a
description of: the test objectives of each test phase (i.e., verification,
demonstration, evaluation), schedule of tests (as coordinated with other
disciplines); procedures for selection of maintenance tasks when faults are to
be simulated; any special maintenance tasks, such as those requiring unique
skills, equipment, test methods, etc., to be performed, including method of
demonstration; test method (see Section
3.6 ), including accept/reject decision criteria, risks, etc.; data acquisition methods; data analysis methods and procedures; specific data elements; type and schedule of reports to be generated, if any; and the maintenance tasks to be verified, demonstrated, and evaluated.
Retesting Requirements - Provide a provisional schedule for special or repeat testing required to investigate any deficiencies or trouble areas. Deficiencies should be corrected in any item which has failed to meet the acceptance criteria. The corrected portions of the item and any other portions of the item affected by the correction should be retested during retest. The maintenance tasks to be demonstrated should be as designated by the
8This plan should be an integral part of the overall test plan for the development program.
