When it comes to existing PMs, the first thought is usually to search in the Computerized Maintenance Management System (CMMS). Of course, this is a valuable resource, but we may be missing other activity happening in departments of the plant, mill, or mine. It is very common that different crafts/departments have set up their own Preventive Maintenance Systems for components and equipment.

In terms of Maintenance Methods, there are three choices for existing equipment. They are Operate to Breakdown, Fixed Time Maintenance, and Condition Based Maintenance. Operate to Breakdown: The equipment is run until it breaks down. Fixed Time Maintenance: The replacement of parts or equipment on a fixed/scheduled frequency.  Condition Based Maintenance: The problem is found and fixed at the time when it is discovered. It is a common assumption that Condition Based Maintenance is always the most cost effective. While this is commonly the case, it is not always true.
