PMI-CPMAI explicitly includes conducting AI go/no-go assessments as a gated decision mechanism to determine whether conditions are sufficient to proceed. In CPMAI-aligned practice, stakeholder alignment on objectives is necessary but not sufficient; readiness must also cover data availability, permissions, privacy/legal constraints, and the feasibility of meeting acceptable performance metrics. A go/no-go assessment brings these prerequisites into a structured review, allowing the project manager to document assumptions, identify critical gaps (e.g., data rights, retention limits, PII handling), and decide whether to proceed, pivot, or stop before incurring avoidable cost and rework. Starting model development prematurely (A) can create downstream rework if data access or compliance fails. Jumping to deployment planning (C) is even more premature when foundational data and legal feasibility are unknown. Buying compute (D) addresses capacity, not feasibility. The PMI-aligned action that enables responsible forward movement is the formal go/no-go gate using readiness criteria.
