Define one measurement unit
Choose a repeatable activity: one part, shift, machine or service job. Record material usage and approximate time, then compare similar periods.
- Cost per part or job
- Kilograms per shift
- Cleaning time
Remove inappropriate use
Premium material should not be used for heavy dirt when a robust grade handles the task. Define two or three grades and show clearly where each belongs.
- Right grade for each area
- Short instructions at the workstation
- No mixing between materials
Plan replenishment
A minimum stock level and recurring order limit urgent purchasing. Review use monthly and adjust stock for seasonality and delivery lead time.
- Minimum stock level
- Recurring quantity
- Monthly review
