Measuring OEE starts with a scorecard. How do you use it and what does the information tell you? Start using your Cierpa scorecard now!
What is OEE exactly?
OEE (Overall Equipment Effectiveness) tells you whether you use your production resources efficiently. OEE provides you with the answers to questions like: How often does a machine break down? Why does it stop? What percentage of the maximum machine speed do you actually reach? If you produce non-stop, at full speed, do you produce lots of waste? The power of OEE is that it highlights areas of significant waste and the scorecard is a great tool to help you see this.
What does OEE measure?
OEE measures the difference between ideal and actual output. When a production line operates 24 hours a day, produces at top speed, and delivers perfect quality, then we have an idea of the ideal line output. But what is the actual output and what causes the differences? OEE helps you find out.
Recording OEE can be done manually, semi-automated or fully automated. Manual recording uses a paper-based scorecard. Semi-automated recording uses an online scorecard. Fully automated recording uses automated real-time measurements. Operators will experience the differences in workload of each of these methods, along with the operator actually transferring the scorecard data to the system. The paper-based scorecard is the most labor-intensive measuring method, but is often used because it’s easy and adds no costs. Often, this is the method to get things going. And that’s a good thing, because the team gets a great handle on working with OEE: it’s the best introduction towards automated OEE recording.

How to use the OEE scorecard
The OEE scorecard contains all daily data or shift data, divided into segments. The operator uses the scorecard to record all shift data and to get insight into OEE. Read our note on the optimal usage of the scorecard.
On the scorecard
Three tabs: three shifts
Five-minute blocks: when did the machine run, when did it stop – and why? You can adjust the time segments.
Production orders: codes for order production
Downtime codes: codes for breaks in production that exceed five minutes
Short breaks: description for breaks in production under five minutes
Production table: the central table of the scorecard with an overview of the machine run
Filling in the scorecard
1. First, always record the date, operator name and machine name
2. Fill in the scorecard during the shift
The green line can be marked with an X when the machine runs, with the order number just below. For longer runs, a bigger X or a stripe over the period in question.
The orange line can be marked when the machine stops for more than five minutes, and the downtime code.
Short breaks (below 5 minutes) are recorded in the bottom right column and can be tallied.
3. Record the production table the end of the order or shift
Record order, type of product, amount produced, amount approved, amount rejected, and rotational speed (cycles per hour). The comment boxes are essential to fill in: this is how causes and trends are discovered!
What does the scorecard tell you?
The scorecard provides a clear overview of the production process within a certain timeframe (e.g., an eight-hour shift). It informs on production, downtime, quality, and malfunctions. When the percentages on actual production time, actual output and accepted output are known then you can calculate OEE and start improving. Multiple scorecards clearly show trends and waste once they have been analyzed and visualized via charts. Cierpa OEE software automatically provides you with that visual information.
