The Three-Phase Model

The three-phase rollout model is not a calendar. This is the first and most important thing to understand. Controlled pilot. Expanded rollout. Broad adoption. Each phase has entry criteria based on the results of the previous phase. You advance when you have earned it — when the evidence from the previous phase meets the defined threshold — not when the timeline says it is time to advance. The organization that advances on a calendar regardless of results is the organization that scales its problems.

1. Phase 1: Controlled Pilot Scope: 20-100 participants, single workflow or team, controlled conditions. Purpose: produce conviction and a playbook. Success criteria: defined performance thresholds met, behavioral adoption demonstrated, champion network seeded, rollout playbook documented. Duration: 8-12 weeks. This phase ends with the pilot review and expansion decision.
2. Phase 2: Expanded Rollout Scope: 100-1,000 participants, multiple teams or regions, using the pilot playbook. Purpose: validate that the pilot's success conditions can be replicated at scale. Success criteria: adoption rate threshold maintained, support infrastructure holds, champion network scales, no new failure modes emerge at scale. Duration: 12-20 weeks. This phase ends with a scaled adoption review and broad deployment decision.
3. Phase 3: Broad Adoption Scope: full target population, all workflows, standard operating model. Purpose: make the AI-assisted approach the organizational default. Success criteria: adoption rate meets organizational target, lagging performance indicators confirm transformation, governance model operating as designed. Duration: ongoing. This phase does not end — it transitions into the sustainment operating model.
