The Maintenance Excellence Index (MEI) is a framework designed to evaluate the effectiveness of a maintenance department. Created by Ralph W. Peters, the MEI helps organizations track the performance of maintenance activities through various key metrics. The MEI aims to provide maintenance managers with a comprehensive view of how well their department is performing and how maintenance activities impact an organization's profitability and overall success.
‍

The MEI is built on a selection of 10 to 15 key performance indicators (KPIs) that are chosen based on the organization's specific needs. These metrics are benchmarked, and their performance is tracked over time. Each metric is assigned a score, and these individual scores are combined to generate an overall MEI score, which measures the department’s success in achieving its goals.

‍

The MEI encompasses a wide range of metrics that focus on maintenance's operational and financial aspects. These metrics are then benchmarked against industry standards, allowing you to compare your performance to best practices.
‍

1. Financial Performance

• Overall Maintenance Budget Compliance: Measures how effectively your department adheres to the allocated maintenance budget.

• Maintenance Cost per Unit of Production: Calculates the cost of maintenance relative to the output produced, providing insights into efficiency.

• Consumer or Capital-Funded Jobs Completed: Tracks the completion of maintenance tasks funded by customers or capital investments, indicating the department's responsiveness to external needs.

‍

2. Work Order Management

• Other Planned Work Orders Completed as Scheduled: Measures the percentage of planned maintenance tasks completed on time, highlighting the department's ability to adhere to schedules.

• Schedule Compliance: Assesses the overall adherence to planned maintenance schedules, indicating the department's reliability and predictability.

• Planned Work Orders vs. True Emergency Work Orders: Compares the number of planned maintenance tasks to emergency repairs, revealing the effectiveness of preventive maintenance strategies.

• Craft Time to Work Orders: Measures the time maintenance technicians take to complete assigned work orders, indicating efficiency and productivity.

• Craft Utilization: Calculates the percentage of time maintenance technicians are actively working on tasks, highlighting the department's utilization of resources.

• Craft Performance: Evaluates the overall performance of maintenance technicians, considering factors like efficiency, quality, and adherence to safety protocols.

• Craft Quality and Service Excellence: Assesses the quality of work performed by maintenance technicians, ensuring customer satisfaction and minimizing rework.

• ‍Overall Craft Effectiveness (OCE): Combines various metrics related to craft performance, providing a comprehensive assessment of the maintenance team's effectiveness.

• Work Orders with Reliable Planned Times: Measures the accuracy of estimated completion times for planned maintenance tasks, indicating the department's ability to predict work durations.

‍

3. Preventive Maintenance

• Overall Preventive Maintenance Compliance: Tracks the adherence to preventive maintenance schedules, highlighting the department's commitment to proactive maintenance.

‍

4. Inventory Management

• Gained Value from Craft Utilization: Measures the financial benefits of efficient utilization of maintenance technicians.

• Inventory Accuracy: Assesses the accuracy of inventory records, ensuring that the right parts are available when needed.

• Actual MRO Inventory Reduction: Tracks the reduction in maintenance, repair, and operations (MRO) inventory, indicating the department's ability to optimize inventory levels.

• Number of Stockouts: Measures the frequency of stockouts, highlighting the department's ability to avoid delays due to missing parts.

• Value of Direct Purchasing Cost Savings: The financial savings achieved through efficient procurement practices are calculated.

‍

5. Asset Performance

• Asset Availability/Uptime: Measures the percentage of time assets are operational, indicating the department's ability to maintain equipment reliability.

• Overall Equipment Effectiveness (OEE): Combines metrics related to availability, performance, and quality to provide a comprehensive assessment of equipment effectiveness.

‍

The MEI offers several benefits to organizations aiming to optimize their maintenance operations:
‍

• Tailored to Your Needs: The MEI is customizable, allowing you to select the most relevant metrics to your organization's specific goals and priorities.

• Tracks Multiple Metrics in One Place: The MEI provides a comprehensive view of your maintenance department's performance by tracking multiple metrics simultaneously.

• Focus on Profit Optimization: The MEI emphasizes metrics directly impacting profitability, ensuring maintenance activities align with financial goals.

• Connects Long-term Goals to Day-to-Day Actions: The MEI helps connect daily maintenance tasks to long-term profitability goals, fostering a culture of continuous improvement.

• Increases Staff Engagement: By demonstrating the impact of their work on the organization's success, the MEI can increase staff engagement and motivation.

• Informs Senior Leadership: The MEI provides senior leadership with clear data demonstrating the maintenance department's value, ensuring appropriate resource allocation and support.

‍

Implementing the MEI involves a structured approach:
‍

• Define Success for Your Facility: Clearly define your organization's objectives, particularly those related to profit optimization, and establish success criteria for your maintenance department.

• Select Key Metrics: Choose the metrics that will best measure the success of your maintenance efforts, drawing data from your CMMS (Computerized Maintenance Management System) and financial software.

• Set Benchmarks and Goals: Establish specific goals for each metric based on industry best practices and benchmark your performance against these goals.

• Assign Weights to Metrics: Assign weights to each metric, reflecting their relative importance in achieving overall success.

• Create a Tracking Spreadsheet: Develop a spreadsheet to track each metric's current performance, goal, score, weighted value, and overall MEI value.

• Track Progress: Regularly monitor each metric's progress and update your scores at set intervals to stay on track.

• Take Action: Identify areas for improvement based on your tracked progress and take actionable steps to enhance performance and increase your MEI score.

‍

A CMMS (Computerized Maintenance Management System) is a powerful tool that can significantly enhance the effectiveness of the MEI. CMMS software provides a centralized platform for managing maintenance data, including work orders, inventory, and asset information.
‍

By integrating your MEI with your CMMS, you can automate data collection and analysis, streamlining the tracking and reporting process on key metrics. This allows you to focus on interpreting the data and taking action to improve performance.

‍

The MEI is a valuable tool for maintenance managers seeking to measure and improve the overall effectiveness of their department. By tracking key metrics that directly impact costs and profits, the MEI provides a clear picture of your department's performance, allowing you to identify areas for improvement and justify the resources invested in maintenance. By implementing the MEI and leveraging the power of a CMMS, you can optimize your maintenance operations and drive significant improvements in efficiency, cost-effectiveness, and overall asset performance.
