Execution drill: program in trouble
Tell someone how to act on this idea: "The execution deep-dive doesn't ask if you can draw a Gantt chart."
Step 1 of 4
The execution deep-dive doesn't ask if you can draw a Gantt chart. It hands you a fire: a migration is slipping and ML, Infra and Finance disagree on the path. They want to watch you re-baseline scope, triage risk, move people who don't report to you and force a decision - with an artifact at the end, not just a story.
The scenario: you're migrating inference serving to a new GPU pool to cut cost. It's two weeks behind. ML wants to pause for a model change, Infra wants to push through and Finance wants the savings this quarter. Run the recovery.

Run a slipping program in this order. The forcing escalation is the gate - nothing leaves the room without a dated decision.

- Savings slip past quarter end
- Impact × likelihood

- You (TPM)
- Mitigation / trigger
- Re-baselined date + Thursday go/no-go to protect the quarter

- Dual-running both pools inflates cost

| Risk | Impact × likelihood | Owner | Mitigation / trigger |
|---|---|---|---|
| New GPU pool fails latency SLA under load | High × Med | Infra lead | Shadow-traffic test before cutover; roll back if p99 breaches SLA |
| ML model change collides with migration | Med × High | ML lead | Decouple: migrate current model first, ship model change in the next window |
| Savings slip past quarter end | High × Med | You (TPM) | Re-baselined date + Thursday go/no-go to protect the quarter |
| Dual-running both pools inflates cost | Med × Med | Finance partner | Cap the overlap window; daily cost watch during cutover |
This register - owners, triggers, a forcing date - is the deliverable the round wants to see.
