What is OEE?

Overall Equipment Effectiveness (OEE) is a manufacturing metric that measures how effectively manufacturing equipment is utilized. It combines three key factors:

Availability - Percentage of scheduled time that equipment is available to operate
Performance - Speed at which equipment runs vs. ideal speed
Quality - Percentage of good units produced vs. total units started
OEE Best Practices
1
Start with accurate data collection - Use automated systems to eliminate manual errors
2
Focus on the biggest losses first - Identify and address the largest sources of inefficiency
3
Implement continuous monitoring - Track OEE in real-time for immediate insights
4
Engage your operators - Train staff to understand and improve OEE metrics
Frequently Asked Questions

What is a good OEE score?

World-class OEE is typically 85% or higher. However, this varies by industry. Most manufacturers start around 60% and can realistically achieve 75-85% with proper implementation.

How often should I calculate OEE?

OEE should be calculated continuously in real-time when possible. At minimum, calculate it daily for each production shift to identify trends and issues quickly.

What's the difference between OEE and utilization?

Utilization only measures if equipment is running, while OEE measures how effectively it's running by including speed and quality factors.

How can I improve my OEE score?

Focus on the lowest-scoring component first. Reduce unplanned downtime, optimize changeovers, eliminate defects, and implement predictive maintenance strategies.
