Bryan Weir of Perspective CMMS explains the concept of using ‘Failure Codes’ in your computerised maintenance management system. Having a manageable and practical list of failure codes will help you do statistical analysis of some of the root causes of the maintenance problems. At the same time, the list should be short enough and clear enough for operators and maintenance personnel to easily select the most appropriate code for problem. Mike has provided his example list of codes which you could use as starting point for your setup.
