 Measure your Maintenance and Reliability Processes Utilizing the SMRP Metrics

 

When people talk about maintenance metrics or key performance indicators it seems many of us see we have a lot to learn. Performance measurement is a fundamental principle of management. The measurement of performance is important because it identifies current performance gaps between current and desired performance and provides indication of progress towards closing the gaps. Carefully selected key performance indicators identify precisely where to take action to improve performance.

To achieve this performance there are three inputs to be managed.
 
The first requirement is Design Practices. Design practices provide capable equipment "by design" (inherent capability), to meet the manufacturing performance requirements.

The second requirement is Operating Practices that make use of the inherent capability of process equipment. The documentation of standard operating practices assures the consistent and correct operation of equipment to maximize performance.

The third requirement is Maintenance Practices that maintain the inherent capability of the equipment. Deterioration begins to take place as soon as equipment is commissioned. In addition to normal wear and deterioration, other failures may also occur. This happens when equipment is pushed beyond the limitations of its design or operational errors occur. Degradation in equipment condition results in reduced equipment capability. Equipment downtime, quality problems or the potential for accidents and/or environmental excursions are the visible outcome. All of these can negatively impact operating cost.
The Importance of the Work Order cannot be overstated. Implementation of the suggested key performance indicators for the maintenance function requires a reliable source of data on asset failures, maintenance costs and downtime.

Any time maintenance is performed on an asset a record should be kept. The vehicle for collecting this data is the maintenance work order. 
 
Whenever maintenance is performed against an asset, work order completion data should include the following information:
  • Identification of the asset at the level in the asset hierarchy where the work was performed
  • Date, time and duration of the maintenance event An indication if failure has occurred: yes or no (no if proactive)  
  • When failure has occurred, identification of the failure consequence: {hidden, safety, environment, operational (product quality, throughput, customer service, operating costs) or non-operational involving the cost of the repair only actual costs (labor, materials, services, etc.)
  • Process downtime (loss of production) asset downtime (equipment out of service but process still able to produce)  Queries in your computerized maintenance management system can then be developed to track and report key performance indicators for asset failure, maintenance costs and downtime. 

“The goal is to turn data into information, and information into insight.”

The Society for Maintenance and Reliability Professionals (SMRP), developed standard definitions for metrics used in industry. These metrics were created by the SMRP’s Best Practices Committee using a rigorous development, review, and approval and harmonization process applying them to the SMRP's Five Pillars of Knowledge.
 
 
Members see the value of these metrics as they are aligned collectively to form the framework of the Maintenance and Reliability Body of Knowledge (BoK)—an aggregate of all that is known and understood in the field of maintenance and reliability.
