The relationships between maintainability and reliability and between maintainability and life cycle costs have already been discussed. Maintainability is related to many other design and support disciplines, either providing information to them or receiving information from them. These relationships are influenced and supported by a multi-disciplinary approach to developing and manufacturing a product. This approach is referred to by titles such as systems engineering, concurrent engineering, or Integrated Product Development. Maintainability engineers have the responsibility for developing and fostering these relationships, and cannot fulfill their responsibilities unless they are a part of a team effort. Figure 2 shows some of the key disciplines with which maintainability has a relationship. (Note that design is not a related discipline because maintainabilityis a function of design.) Each of these disciplines will be briefly discussed.
