Formulas Used
- Output per Hour =
Actual Output ÷ Labor Hours - Output per Worker =
Actual Output ÷ Number of Workers - Output per Worker per Day =
(Actual Output ÷ Workers) ÷ Workdays - Variance to Target (%) =
((Actual per Hour − Target) ÷ Target) × 100 - Time-Based Efficiency (%) =
((Standard Time per Unit × Units) ÷ Actual Time) × 100 - Time Savings =
Baseline Time − New Time; Savings (%) =Time Savings ÷ Baseline Time × 100 - Cost Saved =
Time Savings × Hourly Labor Cost - Quality (%) =
Good Units ÷ Total Units × 100 - OEE (%) =
Availability × Performance × Quality ÷ 10000(components in %) - Takt Time (sec/unit) =
Available Time (sec) ÷ Demand (units) - Available Time (sec) =
Shifts × (Hours/shift × 3600 − Breaks × 60) - Capacity Gap (%) =
((Cycle Time − Takt) ÷ Takt) × 100 - Little's Law:
WIP = Throughput × Cycle Time(consistent units) - Shift Capacity (units/day) =
Available Labor Hours ÷ Std Time per Unit - Available Labor Hours =
Shifts × (Hours − Breaks/60) × Workers × Utilization% - Required Workers =
Target Demand × Std Time ÷ (Shifts × (Hours − Breaks/60) × Utilization%) - Cost per Unit =
(Std Time × (Labor + Overhead)) + Material - Profit per Unit =
Price − Cost per Unit; Profit per Hour =Profit per Unit ÷ Std Time - Annual Savings =
Hours Saved × Labor Cost × Periods per Year - Payback (years) =
Project Cost ÷ Annual Savings; ROI (%) =(Annual Savings ÷ Project Cost) × 100 - Weighted Output/Hour =
ΣUnits ÷ ΣHours
