What problem does it solve? Turning a signed project charter into an approved, actionable project management plan requires coordinating ten PMBOK knowledge areas, and skipping any of them leads to rework during execution. This Skill guides the full Planning process group so the WBS, schedule, cost baseline, risk register, RACI, and communications plan are all produced and sponsor-approved before execution begins. ## Core Features & Use Cases - Subsidiary plans across 10 knowledge areas: scope, schedule, cost, quality, resource, communications, risk, procurement, and stakeholder plans integrated into one Project Management Plan. - Quantitative planning techniques: WBS with the 8/80 rule, CPM forward/backward pass, PERT three-point estimation, and Probability × Impact risk scoring, detailed in the references file. - Ready-to-use plan template: an assets template covering scope/schedule/cost baselines, RACI, risk register, and a sponsor approval section. - Use Case: After the charter for a new order-management system is signed, run this Skill to decompose scope into work packages, build the critical path schedule, estimate costs bottom-up, register the top 10 risks, and obtain formal sponsor approval. ## Quick Start Ask the AI to run pm:planning to develop the full PMBOK project management plan from the approved project charter, producing the WBS, schedule baseline, cost baseline, and risk register.
