MAINTENANCE STRATEGIES Right-Size Dividing the hours in a department's backlog by available hours and then following this trend is a common method for determining the size of a maintenance organization. Your Maintenance Organization Christer Idhammar, IDCON Inc. "HOW CAN WE TELL if our maintenance organization is the right size?" I'm accustomed to hearing that question, especially from individuals who are new to the field. Over the years, many maintenance professionals, including myself, have collected substantial data and worked to come up with a simple answer or formula that could finally bring closure to the issue. As a result, some suggest that the size of a plant's maintenance organization should be based on the number of motors, drives, pumps, compressors, and other equipment systems at the site. But that's just one approach. Others believe that right-sizing efforts should be based on estimated replacement value.

Several years ago, I worked with two competing companies. One had maintenance costs of about US$55 per ton of product; the other had maintenance costs of US$120 per ton. Interestingly, their respective cost of manufacturing was about the same. The company with the lower maintenance costs eventually purchased the other. Subsequently, the acquired company adjusted the rules of capitalization and its maintenance costs ended up at the same level as that of its new owner. The question is, had the acquired company capitalized as much as possible because it knew it could be bought?
