01DECISION GATESTAGE 1
Rescue & Release Review
Establish the current state, bottleneck evidence, business and user outcome, build/buy/fix/stop decision, acceptance model, dependencies, risks, and bounded next-stage plan.
Current-state map, decision record, acceptance model, risk and ownership register, fixed next-stage scope.
02DECISION GATESTAGE 2
Production Proof Sprint
Test the assumption most capable of changing the investment decision with a representative vertical slice—not a polished happy-path demonstration.
Working slice, representative tasks, evaluation results, security and operating boundary, cost and latency observations, release decision.
03DECISION GATESTAGE 3
Production Recovery
Implement and integrate accepted increments, test safeguards and failure paths, deploy behind controlled gates, and measure the result in the real workflow.
Accepted increments, automated and human checks, traces and telemetry, release and rollback records, incident and exception paths.
04DECISION GATESTAGE 4
Transfer or Operate
Pair with the people who will own the system, document decisions and operation, and transfer the environments, code, controls, evaluations, and runbooks—or operate a clearly bounded program.
Named owners, repository and environment control, runbooks, training, review cadence, backlog, and continuing evidence obligations.
