War-game a tooling consolidation before license cuts, migrations, and "one platform" claims leave the private room.
Tooling consolidations fail when feature gaps are papered over, when migration effort is dual-counted as savings, when security reviews arrive after the cancel date, and when power users invent shadow tools the next week. A clean vendor scorecard is not evidence that the system can absorb a month of real workflows without quiet rework.
Freeze the consolidation package
State which tools leave, which tool remains, the success metric after ninety days, and the rollback trigger. Attach usage data, feature gap lists, migration owners, contract end dates, and the security review status. If eng, finance, and security disagree on what "done" means, stop and reconcile before the seating pass.
Write the decision you will make if the war game finds nothing new. Also write the delay criteria if a material workflow still lacks a migration path.
Seats that matter
- Engineering or ops. Workflows the surviving tool still cannot clear without custom work.
- Finance. Savings that depend on headcount or licenses you still keep, and exit fees you forgot.
- Security. Data movement, access models, and reviews that land after cancel.
- Power user. Daily paths that will break on week one and recreate the old stack.
- Skeptic. The claim that looks strongest and is least evidenced by usage data.
Attach the same source pack to every seat. Secret exceptions for one team create fake calm.
Loop the review
Feed Pingpong the consolidation memo, usage extract, and migration plan. First pass steelmans the move. Later passes attack from eng, finance, security, and user seats. Final pass turns surviving objections into a narrower cut list, a phased migration, or a hold. Agreement across passes is not proof. Keep the objections that still have evidence gaps.
Force a week-after narrative: what happens if a critical integration fails, if a power user rebuilds the old tool in a spreadsheet, or if security blocks data move after licenses end. If those stories are stronger than your mitigation plan, fix the package before cancel. When the plan announces "one platform," force eng and user seats to invent the FAQ you will need within a week. If you cannot answer with the same facts as the migration plan, the package is not ready.
