Example: A conveyor belt breaks down three times in a month, with repair times of 2 hours, 3 hours, and 1 hour. MTTR = (2 + 3 + 1) / 3 = 2 hours.
Target: Aim for a consistently decreasing MTTR over time.

Preventive Maintenance (PM) Compliance

This KPI measures the percentage of planned preventive maintenance tasks that are completed on time. High PM compliance indicates a proactive approach to maintenance and reduces the likelihood of unexpected breakdowns. In food and beverage, this often includes cleaning, lubrication, and inspection tasks.

Formula: (Number of PM Tasks Completed On Time / Total Number of PM Tasks Scheduled) * 100
Example: 90 out of 100 scheduled PM tasks are completed on time. PM Compliance = (90 / 100) * 100 = 90%
Target: Aim for a PM compliance rate of 95% or higher.

Overall Equipment Effectiveness (OEE)

OEE is a comprehensive KPI that combines availability, performance, and quality to measure the overall effectiveness of a piece of equipment or a production line. It provides a holistic view of equipment performance and identifies areas for improvement. A high OEE indicates that the equipment is operating at its full potential.

Formula: Availability * Performance * Quality
Availability: (Actual Run Time / Planned Production Time) * 100
Performance: (Ideal Cycle Time * Total Parts Produced) / Actual Run Time) * 100
Quality: (Number of Good Parts / Total Parts Produced) * 100
Example: If Availability = 90%, Performance = 85%, and Quality = 95%, then OEE = 0.90 * 0.85 * 0.95 = 72.7%
Target: OEE is often regarded as a benchmark of manufacturing excellence, with 85% considered world class. Aim for incremental improvements over time.

Maintenance Cost as a Percentage of Revenue

This KPI measures the total cost of maintenance as a percentage of the company's total revenue. It provides a high-level view of the financial impact of maintenance and helps you identify opportunities to reduce costs without compromising reliability.

Formula: (Total Maintenance Costs / Total Revenue) * 100
Example: If total maintenance costs are $500,000 and total revenue is $10 million, then Maintenance Cost as a Percentage of Revenue = ($500,000 / $10,000,000) * 100 = 5%
Target: This varies by industry and company size, but aim for continuous improvement and benchmarking against industry standards.
