Create a Work Breakdown Structure

Decompose project scope into a hierarchical set of work packages that can be estimated, assigned, and tracked. The WBS provides the foundation for effort estimation, resource planning, and schedule development by breaking down complex deliverables into manageable components.

When to Use

• After a project charter is approved and scope is defined
• Planning a classic/waterfall project with defined deliverables
• Breaking down a large initiative into manageable work packages
• Establishing a basis for effort estimation and resource planning
• Creating a shared understanding of all required work

Inputs

• Required: Approved project charter (especially scope and deliverables sections)
• Required: Project methodology (classic/waterfall, or hybrid with WBS for planning)
• Optional: Historical effort data from similar projects
• Optional: Team composition and available skills
• Optional: Organizational WBS templates or standards
