3.1 The Project Management Plan

Key Takeaways

  • The project management plan is the master document that integrates and consolidates all subsidiary management plans and baselines
  • Subsidiary plans include scope, schedule, cost, quality, resource, communications, risk, procurement, and stakeholder engagement management plans
  • The three baselines (scope, schedule, cost) form the performance measurement baseline used to measure project performance
  • The project management plan is a living document that is progressively elaborated and updated through integrated change control
  • Only approved changes through the formal change control process should modify the project management plan

The Project Management Plan

The project management plan is the most important document in project management. It integrates all subsidiary plans and baselines into a single, comprehensive document that guides the project from initiation to closure.

What the Project Management Plan Contains

The plan consists of subsidiary management plans and baselines:

Subsidiary Management Plans

PlanPurpose
Scope Management PlanHow scope will be defined, validated, and controlled
Requirements Management PlanHow requirements will be analyzed, documented, and managed
Schedule Management PlanHow the schedule will be developed, managed, and controlled
Cost Management PlanHow costs will be planned, structured, estimated, budgeted, and controlled
Quality Management PlanHow quality policies, objectives, and responsibilities will be implemented
Resource Management PlanHow resources will be estimated, acquired, managed, and released
Communications Management PlanHow project communications will be planned, structured, and monitored
Risk Management PlanHow risk management activities will be structured and performed
Procurement Management PlanHow procurement processes will be managed
Stakeholder Engagement PlanHow stakeholders will be engaged based on their needs and expectations

The Three Baselines

Baselines serve as the approved versions of work products against which actual performance is measured:

BaselineWhat It MeasuresComponents
Scope BaselineProject scope performanceProject scope statement + WBS + WBS dictionary
Schedule BaselineSchedule performanceApproved version of the schedule model
Cost BaselineCost performanceApproved time-phased project budget (excluding management reserves)

Together, these three baselines form the Performance Measurement Baseline (PMB), which is used in Earned Value Management to measure project performance.


How the Plan is Developed

The project management plan is created through the Develop Project Management Plan process in the Planning process group. Key inputs include:

  1. Project Charter — Provides high-level direction and authority
  2. Outputs from other planning processes — Each subsidiary plan is developed through its own planning process
  3. Enterprise Environmental Factors (EEFs) — External conditions affecting the project
  4. Organizational Process Assets (OPAs) — Internal policies, templates, and lessons learned

Progressive Elaboration

The project management plan is not created all at once. It is developed through progressive elaboration — starting with high-level information and adding detail as more is known:

  1. Initial version: Created early in planning with available information
  2. Iterative refinement: Updated as requirements are clarified and risks are identified
  3. Baseline approval: Formally approved as the project baseline
  4. Controlled updates: Changed only through integrated change control
