What's inside

  • The full lifecycle — six phases, twenty stages, and the two board gates
  • Stage-by-stage detail with exit-readiness checklists, saved on your device
  • Find My Stage — describe what your team is doing; it places you in the lifecycle
  • The Testing Framework — eight levels, regression discipline, the go-live gate
  • The Funding Envelope calculator — same model and rates as the site's
  • A curated library of 18 key templates — stage-tagged, bundled offline, opening via your phone's share sheet

Every stage links its key templates — 18 of the most-used, bundled in the app and available offline. The full artefact library lives on the Supporting Documents page.
