Performance

The Performance portion of the OEE Metric represents the speed at which the Work

Center runs as a percentage of its designed speed.

The Performance Metric is a pure measurement of speed that is designed to exclude the effects of Quality and Availability.

Calculation: Performance = Actual Rate / Standard Rate

»» Example:

» A given Work Center is scheduled to run for an 8 hour (480 minute) Production

Activity with a 30 minute scheduled break.

» Available Time = 450 Min Sched - 60 Min Unsched Downtime = 390 Minutes

» The Standard Rate for the part being produced is 40 Units/Hour.

» The Work Center produces 242 Total Units during the Production Activity. Note: The basis is Total Units, not Good Units. The

Performance metric does not penalize for Quality.

Actual Rate = 242 Units / (390 Avail min / 60 min/hr) = 37.2 Units/Hour

Performance = 37.2 Units/Hour / 40 Units/Hour = 93.0%

Quality

The Quality portion of the OEE Metric represents the Good Units produced as a percentage of the Total Units Started.

The Quality Metric is a pure measurement of Process Yield that is designed to exclude the effects of Availability and Performance.

Calculation: Quality = Good Units / Units Started

»» Example:

» A given Work Center produces 230 Good Units during a Production Activity.

» 242 Units were started in order to produce the 230 Good Units.

Quality = 230 Good Units / 242 Units Started = 95.0%

What is TEEP?

TEEP (Total Effective Equipment Performance) is another top-level metric. Where OEE measures effectiveness based on scheduled hours, TEEP measures effectiveness against calendar hours, i.e.: 24 hours per day, 365 days per year.

Calculation: TEEP = Loading x OEE

Where Loading = Scheduled Hours / Calendar Hours

»» Example:

» A given Work Center experiences OEE of 76.6%.

» The Work Center Schedule is 5 Days per Week, 24 Hours per Day.

TEEP = (5 x 24) / (7 x 24) x 76.7% = 54.7%

Stated another way, TEEP adds a fourth metric 'Loading', as shown:

TEEP = Loading x Availability x Performance x Quality

TEEP, therefore, reports the 'bottom line' utilization of assets.

The cascade chart shown above visually demonstrates that TEEP is the combined effect of Loading and OEE.
