• Overall Equipment Effectiveness (OEE) introduced in 1989 by Seiichi Nakajima in his book TPM Development program, and before this KPI, people were monitoring equipment performance through availability and downtime only. 
• It is an important KPI in manufacturing that measures the efficiency and productivity of any equipment to define how effectively equipment is utilized and which opportunities to you can do to maximize efficiency. 

• It combines three key factors: Availability, Performance, and Quality. Achieving high OEE is essential for maximizing production efficiency and minimizing waste. 
• We do recommend to select a bottleneck machine, then do the following steps, then repeat or move to another machine.
•  Here are some best practices to help you maximize OEE:

1. Accurate Data Collection

• Document Downtime: Record all instances of downtime, including planned maintenance and unexpected stoppages, and listen to the operator about stoppage or problems which he is facing. This helps in identifying patterns and root causes of inefficiencies.
• Track Performance: Monitor the speed of production compared to the maximum possible rate. This includes noting any slow cycles or minor stops.
• Quality Control: Keep a detailed record of defects and rework. This ensures that only good parts are counted towards your OEE.
• Focus on lowest OEE element to enhance it and find root causes of each losses.
• Conduct daily lean meeting near to the machine for previous 24 hours then set an action plan to improve.

2. Regular Maintenance and Calibration

• Preventive Maintenance: Schedule regular maintenance to prevent unexpected breakdowns. This improves the availability of equipment.
• Calibration: Ensure that all equipment is calibrated correctly to maintain optimal performance and quality.

3. Operators Training and Engagement

• Training Programs: Provide comprehensive training for operators on best practices and the importance of OEE. Well-trained staff can identify and address issues more effectively.
• Engagement: Involve employees in continuous improvement initiatives. Encourage them to suggest improvements and participate in problem-solving.

4. Implementing Lean Manufacturing Principles

• 5S Methodology: Implement the 5S (Sort, Set in order, Shine, Standardize, Sustain) to maintain an organized and efficient workspace.
• Kaizen: Adopt a culture of continuous improvement through small, incremental changes. This helps in identifying and eliminating waste.
• SMED: it's a method to measure, analyze, and reduce changeover time, which is a one of availability losses.

5. Utilizing Technology and Automation

• Real-Time Monitoring: Use IoT devices and software to monitor equipment in real-time. This allows for immediate response to issues and better data collection.
• Automation: Automate repetitive tasks including data collection, alerts, reports, and analysis to reduce human error and increase consistency in production.

6. Benchmarking and Continuous Improvement

• Set Benchmarks: Compare your OEE against industry standards and strive for world-class performance (typically above 85%).
• Continuous Improvement: Regularly review OEE data to identify areas for improvement. Implement changes and measure their impact on OEE.

Conclusion

By following these best practices, you can significantly improve your OEE, leading to higher productivity, reduced waste, and better overall efficiency in your manufacturing processes. Implementing these strategies will not only enhance your equipment's performance but also contribute to a more sustainable and profitable operation.
