## Implementation plan

| Phase | Entry evidence | Actions | Owner | Control | Exit evidence | Due date |
|---|---|---|---|---|---|---|
| 1. Design — UX Metrics Library | | During design, use UX Metrics Library to use important terms consistently in decisions and implementation. Start with user research, journey evidence, behavioural analytics, accessibility findings, support demand, and current product outcomes. Name the accountable owner, the evidence reviewer, the decision deadline, and the output that proves this stage is complete. Record exclusions and unresolved questions rather than allowing them to disappear into narrative. The stage closes only when its evidence can be reproduced by someone who did not prepare it. | | | Required output: an agreed definition, examples, exclusions, and related concepts. | |
