Ownership, cadence, accountability
A fractional head owns outcomes: the quarterly strategy with named bets, the roadmap your team executes against, the standing cadence that keeps momentum honest, and the number the board sees. Deliverables include the unglamorous leadership artefacts execution vendors never produce: prioritisation with reasons, decision logs, risk calls on migrations and redesigns, and translation between dev, marketing and money.
With hands available
Because this practice is technical, emergencies get more than direction: a migration wobble or traffic drop gets diagnosed personally rather than delegated into a queue. Leadership with a working senior underneath is the fractional model at its best.
