War-game a specimen chain rewrite by proving each handoff class has a named owner, a measured age-out, and a reverse path before draft chains start governing every custody claim.
Specimen chain rewrites fail when "rewritten" means a status without a decision artifact, when teams dual-count a draft handoff as both approved and live, and when high-risk assays still pin to one thin courier because the chain inventory is incomplete. The review needs one written inventory of handoff classes, one owner who can deny a risky shortcut, and a documented consequence when a failed handoff ages past the deadline.
Name the rewrite under fire
State which specimen classes the rewrite covers, the effective date, which handoffs change, how evidence packs are versioned, and what happens to specimens already in flight. Name the benches that feel it first and the result promises that depend on coherent custody handling. If the memo mixes a specimen chain rewrite with a reagent stockout and a turnaround SLA cut, split them.
Write the decision you will make if the war game finds nothing new. Also write the reverse criteria: the missed handoff, custody gap, or clinician deadline that would force a rewrite rollback within a stated window.
Who must sit
- Lab ops. Handoff timing, age-out math, and what the custody forecast hides if exceptions soften after the policy.
- Quality ops. Audit lag, dual-counted chains, and the message that would leave orphan specimens open past lock.
- Courier ops. Transit capacity, temperature load, and relationship damage with clinics when handoffs jump overnight.
- Finance. Remake-cost load, forecast promises that break in process, and the first ninety days of thicker remedies after a soft rewrite.
- Skeptic. The claim that looks strongest and is least sourced.
Attach the same source pack to every seat: open specimens, handoffs in flight, protected assay classes, custody commitments, and the age-out policy you actually intend to use. Secret data for one seat creates fake agreement.
Run the private fire
Feed Pingpong the rewrite memo, the chain exhibits, and the seating briefs. First pass steelmans the rewrite. Later passes attack from lab, quality, courier, and finance seats. Final pass turns surviving objections into phased handoff rules, mitigations, or a changed recommendation.
Pair with the lab ops lead seat, a reagent stockout stress test, a turnaround SLA cut, and the quality ops lead seat. More operating decisions live in the war-game decisions hub.
Ship the rewrite only when approved and blocked handoff labels can be reproduced from stored specimen exports without a verbal override.
