MANUFACTURING IMPROVEMENT MADE EASY BY VORNE

OEE DISPLAYS

THE BIG IDEA
THE BIG IDEA
Digital OEE displays enhance the manufacturing process by gathering accurate, actionable production data and making it available to operators in real-time. That way, they can make improvements during the shift as opposed to supervisors looking at data retroactively and making changes for the next shift.

DIGITAL PRODUCTION DISPLAYS IN MANUFACTURING

Digital production displays are integrated into manufacturing plants to make accurate, automatically collected production data visible to as many members of your team as possible. This empowers plant employees to act on current information to ensure lines run smoothly and efficiently. These scoreboards can collect and display a variety of metrics, so you can choose what resonates best with your operators and what will best drive action toward the improvements upon which you want to focus.

Why Use OEE Displays?

Overall Equipment Effectiveness (OEE) identifies the percentage of planned production time that is truly productive. An OEE score of 100% represents perfect production: manufacturing only good parts, as fast as possible, with no down time.

Traditionally, OEE lives in offices and meetings. What do we mean by that? Operators capture data using log sheets that record down time, changeover time, and production counts. After the shift ends an admin or supervisor collates the data and generates an OEE report, which is reviewed at the next daily production meeting. Bottom line – the information is too late to drive meaningful proactive improvement on the plant floor. Furthermore, manual data capture frequently suffers from serious accuracy issues (such as underreporting of down time). OEE displays solve both of these problems.

OEE displays automate data capture, calculate OEE in real-time, and identify underlying losses so the team knows how well they are doing during the shift (we call it “winning the shift”). The underlying losses of OEE are expressed in terms of Availability, Performance, and Quality. Going back to the idea of perfect production: “manufacturing only good parts” is perfect Quality, “as fast as possible” is perfect Performance, and “with no down time” is perfect Availability.

Many businesses find that pure OEE as shown above can be a bit abstract for practical use by teams on the factory floor (what does a Performance score of 94.8% really mean?). An interesting alternative for an OEE display is to show Availability, Performance, and Quality in terms of loss (usually lost time within the shift, job, or part run). In other words, show Availability Loss, Performance Loss, and Quality Loss.

This OEE display shows OEE for the shift in real-time, and it shows the underlying losses (Availability Loss, Performance Loss, and Quality Loss) in units that are easily understood by operators – hours, minutes and seconds.

A popular alternative to OEE displays focuses on metrics that enable employees to “win the shift”. A TAED display shows:

  • Target: Real-time count of good parts that should have been manufactured.
  • Actual: Real-time count of good parts that actually were manufactured.
  • Efficiency: Ratio of actual good parts to target good parts.
  • Down Time: A component of OEE Availability; for most companies the largest loss.

TAED is a tool for instantly conveying to plant floor employees how well they are doing – whether they are “winning the shift”.

TAED displays show Target, Actual, Efficiency, and Down Time, and are popular alternatives to OEE displays. We highly recommend them for the plant floor as they provide an effective way for employees to “win the shift” (Efficiency of 100% or more).

Types of OEE Displays

Two types of OEE displays are typically used in manufacturing:

TypeHow It's Used
WhiteboardPortable (on wheels) or fixed (wall-mounted) rewritable boards where KPIs such as OEE are recorded. Whiteboards may be updated at the start of each day, at the start of each shift, or hourly (optimal). Information is not real-time but can influence shift performance when updated hourly. Whiteboards convey a lot of information, but the information is manually captured, not real-time, and not viewable from a distance.
Visual DisplayPlant floor electronic displays that convey OEE and other KPIs in real-time. They provide:
  • Visual cues to alert when special attention is needed
  • Contextual information such as down time during breakdowns, target time for changeovers, and remaining time for breaks
  • Automated data capture for high resolution and accuracy

How to Use OEE Displays

One of the most effective ways of using OEE displays is to provide contextual real-time information on production loss. Here are three simple examples of contextual real-time information that will drive action on the plant floor.

OEE Display showing the line is running slow.
StateDescriptionExample
RunningProactively engages the team by identifying slow cycles (OEE Performance loss), small stops (OEE Performance loss), and poor quality (OEE Quality loss) while running.
Unplanned StopCalls immediate attention to down events (OEE Availability loss). Encourages operators to get equipment up and running as quickly as possible.
OEE Display showing the line is down.
Planned StopProvides a real-time target for changeovers (OEE Availability loss). When the changeover takes longer than the target, it displays a simple alert.
OEE Display showing there is a setup or a changeover.

Remember – the primary goal of using OEE displays is to positively influence behavior and drive improvement actions on the factory floor. Contextual information guides operators to effective actions.

OEE reports are records of what happened in the past. OEE displays are records of what is happening right now – an opportunity to change history before it happens. By displaying OEE and other performance data in real-time, your team can address issues and solve challenges as they occur.
