Maintainability design evaluation is the process of analyzing the maintenance implications of a proposed or evolving design and providing feedback to the designer in a timely manner. A major goal of this evaluation is to ensure that maintainability is designed into the product from the start.
The process starts with a set of standards available to the designer and maintainability engineer. These standards normally consist of a preliminary "use study," maintenance concept, qualitative and quantitative maintainability requirements, and lessons learned. The in-process evaluations refine the maintenance concepts that will later form the basis for the maintenance elements of logistics support analysis.
The depth of this analysis depends on the phase that
the design program is in at the time and the complexity of the equipment being
designed. More complex equipment will need extensive evaluation to ensure that
all maintainability requirements are being met. The design criteria in Appendix C provide a basis for evaluating a design for maintainability.
