Many reactive organizations conclude that RCA is the first agenda item for improving reliability. But after completing a few root cause activities, it's obvious that the results will point to already-known problem areas, such as inferior preventive maintenance (PM) and planning and scheduling. The initial reasoning to start an RCA initiative often follows this train of thought: We have a lot of equipment breakdowns, so . . . step one should be to analyze those breakdowns in order to . . . identify the root cause of the breakdowns in order to . . . eliminate the root causes.
It sounds logical and reasonable when presented this way, but if basic PMs and planning and scheduling aren't in place, most RCAs will point to these deficiencies. Typical outcomes of analyses fall on the wrong amount or type of lubrication, shaft misalignment, unbalanced equipment, missed inspections and overhauls. The "human" or "process" causes often relate to poorly planned work orders.
