Predictive Maintenance (PdM) |
Preventive Maintenance (PM) |
Approach |
Condition-based maintenance, performed as needed based on equipment condition. |
Time-based or usage-based maintenance, performed at regular intervals. |
Cost Efficiency |
High; reduces unnecessary maintenance, leading to savings on labor and materials. |
Lower; can lead to over-maintenance and unnecessary costs. |
Downtime |
Minimized; maintenance is performed just before failure is likely, reducing unplanned downtime. |
Reduced; regular maintenance can prevent some failures but may not be as effective as PdM. |
Equipment Lifespan |
Extended; precise condition monitoring can prevent minor issues from becoming major. |
Potentially extended; however, the risk of over-maintenance can negatively affect equipment lifespan. |
Safety |
Improved; early detection of potential failures can enhance workplace safety. |
Moderate; regular maintenance reduces some risks, but may not catch all potential failures. |
Data-Driven Decisions |
Enabled; uses data analytics and monitoring for informed maintenance decisions. |
Limited; decisions are based on general schedules, not specific equipment condition. |
Resource Utilization |
Optimized; resources are used efficiently as maintenance is performed based on actual need. |
Less optimized; resources may be used for maintenance that isn't currently necessary. |
