A polished concept can make execution look more settled than it is. A capability review should identify which parts can be delivered and which depend on unresolved resources or expertise.
IDEO.org's Capabilities Quicksheet examines what is needed to execute a proposed solution. IDEO.org Design Kit — Capabilities Quicksheet.
Use the actual proposal
For a character range, list the activities implied by the design, distribution and support model. Keep unsupported capacity, cost and timing assumptions visibly open.
Prioritise the gap
Identify which missing capability prevents the next meaningful evaluation or commitment. Obtain evidence proportionate to that decision rather than filling the sheet with optimistic statements. The review is useful when it changes the plan, scope or sequence before the team promises an outcome it cannot yet support.
