Par levels without a spreadsheet degree
- Count usage, not stock. Pick two typical weeks and record what leaves the shelf, not what sits on it.
- Set par at two weeks of usage plus a half-week buffer for anything with a delivery lead time under three days.
- Set par at four weeks for allocated or seasonal items — rapid tests, flu vaccine ancillaries, splinting.
- Put the number on the shelf, not in a file. A laminated card with item, par, and reorder point beats any portal.
- Review quarterly. Provider mix changes faster than most par sheets do.
The most common error we see is par levels set from case quantities rather than usage — a clinic using 40 gloves a week carries a case of 1,000 because that is how it ships.
