The methodology turned into a tool. Walk it stage by stage against your own programme to see where you sit, where you diverge from the methodology, and what the next move looks like.
No sign-up. No gate. Your stage readiness state stays in your browser — close the tab, come back next week, your work is still there.
Fifteen tabs covering Introduction, Stages, Timeline, Business Case, Governance, Roles, Roles by Phase, RACI, Data, Integration, NFT, Vendor & Platform, Decks & Audiences, Stage Finder and Exit Criteria. Self-contained, runs in your browser.
Launch the Method Command Centre →A standalone surface for the eight-level testing model with explicit role distinctions per level — from unit and integration through UAT, NFT and operational acceptance.

The Command Centre is the active expression of Keystone — the written methodology pages on this site are the reference. The two cross-link, so you can move between "what does the methodology say about Solution Design & Full Business Case (S12)?" and "where is my S12 actually?" without losing your place.
Every stage with entry criteria, key activities, exit criteria, named owners, and the artefacts that get drafted. Click any stage to expand.
Six phases, twenty stages, the gate scheme overlaid — two Board Gates, one Executive Go/No-Go, the Phase Checkpoints, the Go-Live event marker. Pattern selector for single-pillar, multi-wave and dual-pillar variants.
Four checkpoints across the lifecycle — Value Definition (S2), Funding Envelope (S6), SI ROM (S9), Full Business Case (S12) — with variance ranges per checkpoint, not a single number at the end.
Executive Sponsor Group, Steering Committee, Design Authority. Formation points, cadences, decision authority, and what each body owns vs. endorses.
The full role catalogue plus Roles by Phase and a sortable RACI matrix. Process Owners, SMEs, Benefit Owners — named, distinguished, with the cross-pillar markers and the non-transferable sign-off rule.
What you should have evidenced by now, what's outstanding, what's been formally accepted with rationale rather than waved through. Persists across sessions.
Data Owners by domain, Data Lead, Data Architect, SI Data Migration Lead — and how they interact across Discovery, Design, and the Mock Loads through cutover.
Estate-on-a-Page, Integration-on-a-Page, the Integration Lead's working group, and the integration design decisions recorded as Architecture Decision Records at S12.
Answer a few questions about your programme and the tool tells you which stage you're functionally in — often different from the stage your team thinks they're in.

How it works under the bonnet
The Command Centre is a self-contained HTML and JavaScript file that runs entirely in your browser. There is no server, no backend, no account, no login. Your stage readiness state is saved to your browser's local storage — it persists across sessions on the same device, but doesn't follow you to a different browser or computer.
If you want to share your assessment with a colleague, or move it between devices, the tool has an export-to-file feature. Save it, send it, import it on the other device. The methodology is openly published; the data about your programme is yours.
None of your assessment data leaves your browser. The site uses privacy-respecting analytics for visitor counts only — no cookies, no tracking, no profile-building. See the privacy notice for the full picture.
