YOUR LINE
Currency
120 h/wk

Planned production time — when the line is scheduled to run. E.g., 2 shifts × 12h × 5 days = 120.

50 wk/yr

Weeks per year you run, after planned shutdowns and holidays.

18 h/wk

Average unplanned stoppage time per week — breakdowns, unplanned changeovers, waiting. Don't include planned maintenance.

60 /hr

Your line's maximum rate at full speed — the design or nameplate rate. Units per hour.

5,000 /wk

Total units produced per week, including any that were scrapped or reworked.

5.0%

Share of produced units that are defective (scrap + rework). Quality = 100% − this.

$20.00

Profit per good unit (price − variable cost). Use margin, not full price, to avoid overstating.

85%

The OEE you're aiming for. 85% is the recognised world-class benchmark.
