What does a lost hour cost your cell?
Put in one cell’s numbers. Nobody writes down the minutes lost waiting on material or on a slow changeover. A machine down for twenty minutes rarely makes the log either. By the end of the month it adds up to real money.
What it costs
- Parts short per shift
- 38
- Parts short per month
- 1,575
- Margin lost per month
- $9,450
- Per year
- $113,400
1,575 parts short per month. $9,450 margin lost per month, $113,400 per year.
For one cell. Minutes lost × parts per hour ÷ 60 × shifts × days × margin. It leaves out overtime to catch up, expediting and late penalties, which usually make it worse.
Finding the minutes
You can’t fix minutes you can’t see. An hour-by-hour board puts plan against actual every hour, with the running gap. A slow hour shows up while there’s still time to recover it.
