Everyone who worked a floor in 2020 remembers what running out of masks felt like. Par levels are the boring operational fix that makes sure it never happens to your unit again — and they’re not complicated once you build them right.
A par level is the minimum stock that triggers a reorder. Set it too low and you’re always one bad week from empty; set it on last quarter’s calm and a surge wipes you out. The right par is real burn rate plus a surge buffer plus your supplier’s lead time.
The second half of resilience is vendor redundancy. A single supplier’s outage shouldn’t become your outage, so vet at least two vendors per critical item. We learned this moving meals — redundancy in the chain is the only thing that survives a crisis.
Build the par sheet, name the backup vendors, and put the reorder trigger on someone’s actual job — not “when we notice.” That’s the whole system, and it’s the difference between never running short and learning the 2020 lesson twice.
