How each S4 stage applies here| Stage | What it changes |
|---|
| Signal | Collect representative data samples, source ownership, freshness notes, known quality problems and the named owner of the workflow outcome. |
|---|
| Synthesis | Build a prioritised gap register with evidence, owners and proposed resolutions, plus a candidate pilot with boundaries, criteria and access requirements. |
|---|
| System | Confirm integration points, interview the process reviewer and technical-incident holder, and test whether policy questions block a bounded internal trial. |
|---|
| Scale | Review findings with business and technical owners, track gap closure against the register, and extend from a drafting trial only when dependencies clear. |

Illustrative readiness example
A 60-person insurer asks whether a claims-summary assistant can proceed. Signal records that claim notes come from three systems, one lacking a named owner. Synthesis produces a gap register with eleven items: four confirmed weaknesses, seven missing facts.
System interviews the process reviewer and confirms she lacks capacity to review during peak months. Scale recommends a two-week drafting trial on closed claims only, defers automated customer letters, and assigns the data-ownership gap to the COO with a resolution date. The board sees evidence per dependency before any procurement starts.
Written teaching example with hypothetical inputs, not a client result.
Operating metric: Share of gap-register items with evidence, owner and resolution date.
