01Fractional
Named day-count per month · no fixed end dateFull accountability for the governance layer throughout, at a named day-count per month with no fixed end date.
OutcomeThe organisation builds internal capability alongside a live accountability structure rather than in its absence.
BenefitThe engagement builds toward its own exit rather than creating a permanent dependency.
02Interim
Defined tenure · full time · named exit dateA defined tenure, full time, with a named exit date and a successor identified before the engagement begins.
OutcomeThe engagement closes when the operating model is mature enough to carry it, not when the calendar runs out.
BenefitThe transition is planned before the programme starts, not negotiated at handover.
Default03Full mandate
Complete conversion accountability · programme durationComplete accountability for the programme's investment-to-outcome conversion for its duration: financial governance, benefits baseline, governance architecture, and cross-domain coordination. Delivery management runs underneath as a separate discipline.
OutcomeOne seat owns the full programme from capital commitment to steady-state handover.
BenefitRemoves the gap between the person responsible for delivery and the person accountable for value, which is where most programmes lose the conversion.
