Six Sigma and Beyond: Design for Six Sigma, Volume VI

After the equipment has been installed and the run-off has been performed, the Durability phase of the cycle begins. The PM program now begins to utilize the R&M team member more as a team leader than a participant. Durability, as defined in the TE supplement, is the "ability to perform intended function over a specified period under normal use (with specified maintenance, without significant deterioration)." As the machinery begins to acquire additional operation hours, PM personnel identify issues and take corrective action. These issues and corrections are fed back to FMEA personnel and R&M planners as lessons learned for the next generation of machinery. Whether these corrections involve the design of the machinery or the maintenance schedule/ tasks , each must be incorporated into the continuous improvement loop.
