Claim
For PMs, leads, and operators acting without formal authority: when it is not clear who decides, the answer is you. Don't get stuck. The shared interest of every team is progress, impact, and momentum, and acting on that interest is the career-positive move.
Mechanism
Most cross-functional work stalls in ambiguity. Waiting for a designated decider creates queues; the queue itself becomes the bottleneck. An operator who decides — and explicitly names the decision, the rationale, and the reversal path — converts ambiguity into action. The decision is reversible if wrong; the inaction usually is not. The team's energy aligns to whoever creates motion.
Conditions
Holds when:
- The decision is reversible (Bezos Type 2) or low-cost to undo.
- The operator has enough context to make a competent call.
- The org culture rewards momentum and tolerates honest mistakes.
Fails when:
- The decision is one-way / high-stakes (Type 1) and warrants formal escalation.
- The operator lacks context and will make an obviously wrong call.
- The org punishes anyone who acts without permission, regardless of outcome.
Evidence
"If you're not sure who the decision maker is, one, it's probably you... Don't get stuck. Too many people get stuck and it makes your work terrible. What do we all care about? Progress, impact, momentum."
Claire Hughes Johnson scaled Stripe from 160 to 7,000+ as COO. The "force for positive momentum" rule is an operating norm she repeated across the org and named explicitly in Scaling People.

Signals
- Cross-functional decisions get logged and shipped within days, not weeks.
- Reversal events are visible and uncontroversial (decision was wrong, we backed out, no career penalty).
- Teams stop routing every choice up the chain and start defaulting to motion.
Counter-evidence
In high-stakes regulated domains (finance, healthcare, security), defaulting to action without authority can be costly or illegal. The rule is conditional on Type 2 reversibility; Type 1 decisions still need their formal owners.
