Maintainability is defined as an inherent characteristic of a system or product design pertaining to the ease, accuracy, safety and economy in the performance of maintenance action; a design parameter related to the ability to maintain. Full implementation of design for maintainability will improve project return on investment. It will help designers and contractors by illustrating methods of integrating maintainability knowledge into project design and construction.

Research conducted by the CII Design for Maintainability Research Team indicates that:

  • Maintainability is an emerging improvement trend in industry that is inconsistently applied.
  • When aligned with business and project goals, maintainability can enhance a project performance while lowering life cycle costs.
  • To properly implement maintainability, an organization must commit to maintainability and provide necessary resources, including necessary work-hours, early in the project process, preferably during pre-project planning.
  • The CII Model Process helps organizations initiate and improve design for maintainability programs.
