SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

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.

Frequently Asked Questions about pm-planning

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a project management plan in PMBOK?▼

Develop subsidiary plans for all ten knowledge areas, then integrate them into one Project Management Plan. This Skill walks through WBS creation, CPM/PERT scheduling, cost estimation, risk planning, and RACI, ending with formal sponsor approval.

How to build a WBS with the 8/80 rule?▼

Decompose the project from phases down to work packages, where each package takes no less than 8 and no more than 80 hours of effort. Document each package in a WBS Dictionary with acceptance criteria, owner, effort estimate, and dependencies.

What is the difference between CPM and PERT scheduling?▼

CPM uses forward and backward passes to find the critical path where float equals zero, determining minimum project duration. PERT adds a weighted estimate (O + 4M + P) / 6 for activities with high uncertainty such as new technology or ambiguous requirements.

When should I not start project planning?▼

Do not plan without a signed project charter, since planning without formal authorization produces work that can be rejected. Also return to Initiating if business aspects remain unclear, because planning on ambiguous scope creates baselines that will not hold.

How accurate are cost estimates made during planning?▼

Planning-phase estimates carry roughly plus or minus 10 to 20 percent accuracy, better than the 50 percent of initiating but still estimates. Committing exact dates and costs in contracts based on planning estimates alone is risky.

Why does a RACI matrix need exactly one Accountable per activity?▼

Multiple Accountable assignments on one activity mean nobody is truly accountable for the result. The rule requires exactly one A per activity, while multiple Responsible parties are acceptable and missing R or A signals an accountability gap.
