Units of equipment should be designed to minimize the numbers and types of auxiliary equipment and tools required to service them.
Additional Information:
Tool requirements should be coordinated across the modules to minimize the number of different tools needed. For example, designers may design modules for the same type of screwdriver rather than requiring a slightly different one for each. The development of tool requirements requires an understanding of the maintenance tasks and the equipment's characteristics. The goal of minimizing the number and types of tools should be addressed early in the equipment design process, and then throughout design and development.
