Score a Fractional or Interim CTO on Five Dimensions
Fractional or Interim CTO
Companion to The CTO You Actually Need · Updated 2026-09-29
| Dimension | 60 days | 120–180 days | End or one year |
|---|---|---|---|
| Decision value | Important decisions are clearer and no longer waiting for undefined ownership | Repeatable decision mechanisms exist | Internal leaders can continue them |
| Scope and availability | Charter fits time and emergencies have coverage | Scope changes are explicit rather than absorbed | Engagement ends, narrows, or converts based on evidence |
| Transfer | Internal owner shadows and receives artifacts | Internal capability is demonstrably stronger | Dependency on external CTO falls |
| Independence | Recommendations show alternatives and vendor conflicts are disclosed | Company can challenge advice and choose other providers | No hidden commercial dependence remains |
| Permanent model | Full-time need and role design are being tested | Search or internal succession is clear where required | Handover is complete and incentives did not distort successor choice |
