- Does your plant have capacity you are aware of but can’t tap into reliably?
- Can performance be measured comparatively across all production areas?
- Is there a bottleneck effecting the total plant performance?
When considering the efficiency of production resources one must consider at least machines, process and people. OEE (Overall Equipment Efficiency) is a powerful performance indictor that can be simply calculated based on Availability (Time), Performance (Speed) and Quality (Product Scrap).
OEE provides an easy to understand, single measurement of efficiency and is typically supported by tools that can assist with continuous improvement where required.
What is OEE?
OEE is an essential metric and basic methodology for manufacturers pursuing a 'lean' manufacturing strategy - that is ‘zero waste’ in their ‘value streams’.
OEE is simple and practical. It takes the most common and important sources of manufacturing productivity loss, places them into three primary categories and distils them into metrics that provide an excellent gauge for measuring where you are - and how you can improve! OEE isn’t enough for root cause analysis on its own but measures the effectiveness trend of improvement actions.
OEE is frequently used as a key metric in TPM (Total Productive Maintenance) and Lean Manufacturing programs giving you a consistent way to measure the effectiveness of TPM and other initiatives by providing an overall framework for measuring production efficiency.
