Drive a Cross-Functional Launch (TPM)

What interviewers evaluate

• Do you establish a clear goal, scope, and definition of done?
• Do you map dependencies and the critical path across teams?
• Do you set up ownership (RACI), cadence, and communication?
• Do you identify and mitigate risks proactively (not react)?
• Do you plan the launch itself (readiness, rollback, comms)?

A framework to structure your answer

1. Define - the launch goal, scope, success criteria, and a hard definition of done across all teams.
2. Plan - break work into milestones, map cross-team dependencies, and find the critical path.
3. Ownership - assign clear owners (RACI), set a cadence (standups/syncs), and a single source of truth.
4. Risk - identify top risks early, with owners and mitigations; track them visibly.
5. Launch readiness - a go/no-go checklist, staged rollout, monitoring, and a rollback plan.
6. Communicate - keep stakeholders aligned on status, blockers, and changes throughout.

Try structuring your own answer first, then reveal a strong worked example.

Common variants

• A dependency team says they'll be 3 weeks late. What do you do?
• How do you run a launch with no formal authority over the teams?
• Walk me through how you'd plan a migration affecting many services.

Pitfalls to avoid

• Treating it as scheduling only, ignoring dependencies and the critical path.
• No clear ownership - everyone and no one is responsible.
• Reacting to risks instead of surfacing and mitigating them early.
• Big-bang launch with no staged rollout or rollback plan.
• Status updates that report activity, not blockers and risk.

Likely follow-ups

• Backend slips and threatens the date. How do you respond?
• Two team leads disagree on scope. How do you resolve it?
• How do you decide go vs no-go on launch day?
