Two teams move boxes all shift. Which one do you think is at its best, most productive pace? Take your pick.
The right machine does the heavy work — and lifts the number. Team A's forklift moves loads no pair of hands can match. Big output isn't always big effort.
What you move matters: the size, the weight, how fragile it is, how careful you must be scanning it in. Two teams, two different jobs.
How you move matters most. Team A lifts in the safe zone — between knees and shoulders. Now look at Team B below: one can't see over his box, one isn't watching his path. Fast today, but someone gets hurt. Never trade safety for speed.
A good supervisor clears the way — spotting jams, fixing what's broken, getting the right tools to the team. Their job is to remove what slows you down.
For both teams, the Zone is the same sweet spot: Performance between 100% and 120%. But look at the cases-per-hour that lands there — different for each team, and different from where we started. Same Zone, different numbers.
Neither team was in the Zone. The big number told you nothing.
Don't measure raw cases. Measure against the team's target — its standard.
More isn't better. Past the Zone, you trade safety and quality for speed.
Equipment, product, method & safety, and supervisors all move the number — so every team's target is different.
