Why is the Work Order the Prime Source for Reliability Info?
The work order provides the most comprehensive description of work accomplished, repairs parts used, reasons for failure, and causes of failure. Over the life of the equipment, the work order tracks total cost of ownership and life cycle cost as they accrue over time, allowing replacements or major repair decisions to be made at the most economical point in time. As work orders are completed and signed off by the supervisor, the planner makes one final review before the work order is closed in maintenance. This
process allows the planner to have a continuing picture of equipment problems of all
types and magnitude. From this pure observation of work orders plus the analysis of
work orders, the planner can play a very important role within a strategy of continuous reliability improvement.
