Production Metrics: Settings, Definitions, Calculations, and Acronyms

Production Metrics - remember, if you measure it, it will improve. 

Production Metrics allow L2L users to track and display various measurables. Which metrics you use and display are controlled by enabling or disabling them individually in the Production Module under Settings > Production Statistics 

While everyone has visibility to enabled Production Statistics, only those users with Administrator Level access in the Production Module are able to modify which metrics are utilized and displayed. 

Earned Hours (E-Hrs)

(Actual * Planned Takt Time) / 3600

Labor Minutes Per Unit (LMPU) †

(Operator Count * (Planned Production Minutes + Non Production Minutes))/Actual           

Labor Hours Per Unit (LHPU) †

(Operator Count * (Planned Production Minutes + Non Production Minutes) / 60 ) / Actual Man Hours (Operator Count * Planned Production Minutes) / 60)

Man Hours †

(Operator Count * Planned Production Minutes)/ 60

OA % (Operational Availability) †

(Planned Production Minutes - Production Downtime Minutes - Planned Downtime Minutes) / Planned Production Minutes × 100

Planned downtime is subtracted only when the dispatch type is configured to exclude planned downtime from the availability metric.

For examples and setup details, see OA % (Operational Availability).

OEE % (Overall Equipment Effectiveness)

OA% * Quality% * Performance per Part%

• OA% = (Planned Production Minutes - Downtime Minutes) / Planned Production Minutes * 100
• Quality% = Actual / (Actual + Scrap)
• Performance per Part% = (Cycle Time / Run Rate)
• Run Rate = (Planned Production Time - Downtime) / (Actual + Scrap)

Parts Produced per Man Hour (PPMH) †

(Actual+Scrap)/(Operator Count * Planned Production Minutes)

Parts Produced per Hour (PPH) †

(Actual+Scrap)/Planned Production Minutes

PEFF (Production Efficiency) †

Actual/Demand * 100

Pace †

(Actual - Demand)

Pitch Pace (Number of Pitches Ahead/Behind) †

(Actual-Demand) / (Average Demand To Date)

Production Quality/Yield Percentage

Actual/(Actual+Scrap)

Scrap %

Scrap/(Actual + Scrap) * 100

Theoretical Efficiency

Actual Parts Produced / Theoretical Parts per Pitch

• Theoretical Parts per Pitch = Planned Production Time in Seconds / Line Cycle Time in Seconds

Performance Per Part

Cycle Time / Run Rate

• Run Rate = (Planned Production Time - Downtime) / (Actual + Scrap)

Time Per Unit (TPU) †

Total Operator Count * (Planned Production Minutes - Downtime Minutes) / Actual Production

Non Productive Minutes                   

Operator Count * Downtime

Labor Efficiency †

Earned Minutes / Available Minutes

• Available Minues = Planned Minutes - Planned Changeover Minutes
• Earned Minutes = (Actual Parts * Planned Cycle Time) / 60
• Planned Cycle Time = (Planned Production Minutes / Demand) * 60 

Labor Efficiency (Ideal Cycle Time)

Labor Efficiency (with Ideal Cycle Time) = Earned Minutes/ Available Minutes

Available Minutes = Planned Minutes - Planned Changeover Minutes

Earned Minutes = Actual Parts * Ideal Cycle Time / 60

Rejects %

Reject / (Actual + Reject) 

 

DPMU (Defects per Million Units)

Total # of Defects / Total # of Units produced (including scrap) x 1000000 

 

Note: If any of the above labels are left blank, the Reports that use these metrics will use an internal system code in its place.

† Data gathered from the current pitch will be prorated. You can read more about it in our Prorated Production Metrics article.
