War-game a par level cut by proving each storeroom lane has a named owner, a measured age-out, and a reverse path before draft pars start governing every storeroom cart.
Par level cuts fail when "ready for census" means a status without a decision artifact, when teams dual-count a draft par as both aspirational and live, and when specialty item families still pin to one thin materials desk because the lane inventory is incomplete. The review needs one written inventory of storeroom lanes, one owner who can deny a risky shortcut, and a documented consequence when a failed par ages past the deadline.
Lock one par family before scale
State which item classes the cut covers, the effective date, which par lanes change, how versions are stored, and what happens to carts already in flight. Name the units that feel it first and the safety promises that depend on coherent materials handling. If the memo mixes a par level cut with a gloves stockout and an OR case-cart delay, split them.
Write the decision you will make if the war game finds nothing new. Also write the reverse criteria: the missed lane, fill gap, or case deadline that would force a par level cut rollback within a stated window.
| Storeroom lane | Owner | Age-out | Reverse path |
|---|---|---|---|
| Standard unit cart | Named materials charge | Measured hours | Documented hold |
| OR specialty dual path | Materials ops | Measured hours | Documented restore |
| ICU bridge cart | Unit charge nurse | Measured hours | Documented re-route |

Par break points
- A specialty item class stays soft while the aggregate materials dashboard stays green.
- Two teams claim the same lane ownership and neither can force a freeze at week end.
- A restore has already left a cart without a trusted par state.
- The primary par export lags beyond the planned observation window.
- An operator skips a par gate because a case cutoff is near.
For each break point, require detection time, unit impact, containment, and the authority to force a par level cut rollback. Commands and export links belong in the runbook.
Seat the par package
Feed Pingpong the cut memo, the lane exhibits, and seating briefs for materials, perioperative, nursing, and pharmacy. First pass steelmans the cut. Later passes attack from those seats. Final pass turns surviving objections into phased lane rules, mitigations, or a changed recommendation. Agreement across passes is not proof. Keep the objections that still have evidence gaps.
Pair with the materials ops lead seat, a gloves stockout stress test, a linen par cut, and an OR case-cart delay. More operating decisions live in the war-game decisions hub.
Ship the cut only when approved and blocked par labels can be reproduced from stored materials exports without a verbal override.
