Build-an-X workflow producing a project-level risk register - risks to project execution (schedule slippage, environment instability, people / staffing, vendor / dependency, scope creep) rather than the product itself. Walks the author through ISO 31000-aligned identification, impact × likelihood scoring, mitigation strategy (avoid / mitigate / transfer / accept), and ownership; the project manager reviews it weekly. Use for release-execution risk. For product-quality risks use product-risk-register-builder, for the per-release product risk table use risk-matrix, and to sign off accepting one specific risk use risk-acceptance-decision-author.
