Dynamic OEE Grade Targets – Lean Playbook
Benchmarks are a welcome mat, not a mattress
Our industry case studies show 80 – 85 % as a solid “good”. Nice, but if the mix shifts and you still chase last year’s number, you are coasting.
The Lean idea behind a moving target
Lean loves stretch goals that are just out of reach. A dynamic grade is nothing more than:
Today’s target = Last week’s sustained best + 0.5 pt
That 0.5 pt nudge is small enough to believe, big enough to feel. Change the increment if your culture needs a gentler slope.
What data you actually need
Forget PhDs. You already log three counts: Planned time, Good parts, All parts. Add two extra signals from MDCplus and you have a richer picture:
-
Short stops < 5 min – automatic from machine states
-
Tool change timestamps – quick barcode scan at the bench
That is enough to flag micro-losses and tooling creep without drowning operators in columns.
How to run the cycle
| Step | Owner | Time needed | Why it matters |
|---|---|---|---|
| 1. Pull yesterday’s OEE by shift | Team lead | 5 min | Live grade keeps talk honest |
| 2. Post on tier-board with traffic lights | Operator | 5 min | Visual scream at the bottleneck |
| 3. Spot the worst red box | Crew | 10 min | Focus beats generic nagging |
| 4. Rapid countermeasure (try-storm) | Same shift | 20 min | Lean action while the pain is fresh |
| 5. Log result in MDCplus note | Lead | 2 min | Keeps tribal fixes visible |
| 6. Friday – set next week’s target | Planner + Supervisor | 15 min | Use the sustained best + 0.5 pt rule |
Repeat until the grade flattens for three weeks – then trim the increment to 0.2 pt or switch focus from Availability to Performance.
Where machine data lifts the load
-
Auto-timestamped stops kill the “stopwatch politics” debate.
-
Live cycle-time charts surface creeping feed overrides before quality shouts.
-
Quick compare of shifts lets operators compete in the open – peer rivalry beats management sermons.
A light touch of AI, if you want it
MDCplus can throw a forecast that suggests tomorrow’s target based on patterns in downtime and scrap. Treat it like weather: a hint, not a command. Operators still own the board.
One-line case snapshot
Switch-gear plant, Line 3: static goal 80 %. After eight weekly nudges the target sat at 83 %, actual grade hit 83.4 %. Zero capex – just disciplined boards and machine signals.
Common traps and simple fixes
-
Target leapfrogs too fast – cap weekly rise at 1 pt.
-
Data gap on legacy machines – cheap current-sensor + digital input covers uptime.
-
Board fatigue – rotate the crew member who presents numbers; fresh voice resets attention.
