00Establish
Set the conditions for responsible work.
Identify the AI overlays, accountable owners, risk and authority boundaries, approved tools and required specialist support. Evidence: an agreed operating context and permission to begin.
01Discover
Understand the problem and baseline.
Observe real user work, explore alternatives and test consequential assumptions. Evidence: a credible problem, baseline, intended benefit and next learning question.
02Define
Agree behaviour and acceptance.
Specify useful outcomes, failure cases, non-negotiable requirements and acceptable variation. Evidence: acceptance criteria and a forecast with its assumptions and conditions.
03Design
Make boundaries and recovery explicit.
Design architecture, user experience, access, data flows, tool authority, fallback and recovery. Evidence: reviewed system boundaries and the decisions behind them.
04Prepare
Make data and evaluation ready.
Establish lawful, appropriate data use, provenance, representative evaluation cases and held-out tests. Evidence: versioned data and an evaluation plan with ownership and thresholds.
05Build
Perform bounded, traceable work.
Give people and agents ready tasks, approved context, cost and retry limits, and clear stop conditions. Evidence: reproducible changes linked to requirements, tests and decisions.
06Verify
Test the system and challenge the evidence.
Combine conventional engineering checks with AI evaluations, security tests, human review and independent validation where required. Evidence: observed results and individually tracked unresolved findings.
07Release
Increase exposure deliberately.
Authorize release against evidence; use staged exposure, observability and rehearsed rollback or containment. Evidence: an accountable go, hold or stop decision and a recovery plan.
08Operate
Observe behaviour, cost and real value.
Monitor quality, drift, delegated actions, incidents, supplier changes and business outcomes. Evidence: operational signals that can trigger intervention, re-evaluation or a new lap.
09Renew or retire
Improve deliberately. Close responsibly.
Revisit assumptions, renew validated components or retire them. Revoke credentials, manage data retention and support users through the change. Evidence: a completed transition with remaining obligations assigned.
