[Industry 4.0](https://resources.intraratio.com/industry-4.0) has [driven innovations](https://www.incentrik.com/learn/how-digital-transformation-is-revolutionizing-industry-4.0-in-manufacturing) in advanced Manufacturing Execution Systems (MES) making data available only a few clicks away. Cycle times, scrap, yields, and downtimes are now calculated in real time giving process owners more time to be [engineers](https://info.stonewallco.com/blog/what-different-careers-can-you-pursue-with-an-engineering-degree)and less time being data gatherers. With key production data collected, Overall Equipment Effectiveness (OEE) calculations are no longer cumbersome to report on. OEE is an important tool in the Six Sigma arsenal to diagnose utilization issues on the factory floor and thus driving continuous improvement efforts.  OEE has long been the standard to measure a factory’s productivity. Manufacturers who utilize OEE metrics see great returns in production efficiency and effectiveness.  1.

The three components of OEE are availability, performance, and quality. All three metrics must be considered when evaluating overall equipment effectiveness, as each component contributes to the overall performance of a process. ### Availability The ratio of Run Time and Planned Production Time (scheduled time). Takes into account any planned and unplanned production stops. A score of 100% means the process is always running during planned production time. Examples of Availability Loss include: Machine downtime caused by failure and unplanned maintenance, material supply issues and changeover time. ### Performance The ratio of Net Run Time to Run Time. Takes into account slow process cycles and small stops. A score of 100% means the process is running as fast as possible. Examples of Performance Loss include: Operator or equipment reduced cycle time, waiting for the next part to arrive (increased idle time). ### Quality The ratio of Fully Productive Time to Net Run Time. Takes into account process defects and reduced yield. Examples of Quality Loss include: Scrapped and reworked parts. ![](https://lh3.googleusercontent.com/hREZ8s-z4rtlI5HXEhfjv8fuJFczej16ssHJR00Fe_-veeFbHdMGaI4F6Q-PT9Lq-JCoXOcDxLhu8c1p3aWhKMeVcKznVfyctN_9L9_svze6UANPNZLpBrn4g06oyuBedbm_lYF41LFq32HdVHfNLoY) ### Calculation for overall OEE: OEE = Availability x Performance x Quality ## The ‘Six Big Losses’ of OEE: The categories below will aid in determining the source of loss for each OEE component and help improve a factories overall utilization.  #### Availability - Planned Downtime - Breakdowns #### Performance - Minor Stops - Speed Loss #### Quality - Production Rejects - Rejects at Start up ## Key Benefits of OEE: OEE gives manufacturers full visibility of their factories' performance enabling them to gain important insights and make efficiency improvements. #### Gather and analyze real-time performance data - Track and report Availability, Performance, and Quality metrics in real-time for the entire line or a single process. #### Quickly identify the root cause of operational issues - Utilize data to understand the source of time and costly production issues. - Pinpoint the crucial Big Losses quickly #### Improve decision-making - No more guesswork, make data driven decisions with more confidence.  #### Optimize production processes - Drill into each process and determine where improvements need to be made - Determine if cycle times are slower than usual or machines need to be recalibrated to improve speed. #### Provide visibility into operations - Metrics and KPIs available at any given time #### Easily monitor progress over time - Analyze data in the past and present to make better decisions in the future #### Save time and resources - Eliminate manual data collection - Increase analysis and improvement time #### Improve overall productivity and efficiency - Drive continuous improvement  ## OEE vs OOE vs. TEEP: Two other metrics that can also aid manufacturers to improve productivity are OOE and TEEP. Overall Operations Effectiveness (OOE): Very similar to OEE calculator however the Availability metric is defined differently. OOE takes into account total unscheduled time (plus scheduled time), versus OEE which only accounts for scheduled time.  **OOE = Availability (for OOE)  x Performance x Quality** **Total Effective Equipment Performance) TEEP:** Measures productivity for ‘All Time’. For example if production in a 24hr day is only 2x8hr shifts; Utilization = 16/24 = 66.6%. If TEEP is 100% the manufacturer is yielding perfect production 24hrs a day.  **Utilization = Schedule Production Time / All Time** **TEEP = OEE x Utilization** ## OEE and MES: There are many software tools available to collect and analyze OEE data. Some tools are standalone products and others are integrated into larger platforms. Today's advanced [Manufacturing Execution Systems (MES)](https://blog.intraratio.com/what-is-a-manufacturing-execution-system)often provide some type of OEE reporting. An [MES system](https://blog.intraratio.com/why-manufacturing-execution-system-mes) that is fully integrated with a factory has all data available to easily calculate and report OEE metrics. The advantage of an [MES](https://www.incentrik.com/learn/what-are-manufacturing-execution-systems-mes)platform with OEE capabilities is that all data collection is automated and factory performance is visible at any given time.  ## Guidance for Better Manufacturing Operations MES provides the digital backbone for [Industry 4.0](https://www.incentrik.com/learn/how-digital-transformation-is-revolutionizing-industry-4.0-in-manufacturing) and the Intelligent Enterprise.
