Work breakdown structure
A work breakdown structure is a hierarchical decomposition of a project's scope into manageable components, such as deliverables, activities, tasks, or work packages.

A work breakdown structure is a hierarchical decomposition of a project's total scope into progressively smaller work packages and tasks.
- How it is used
- Uses WBS to organize project scope before sequencing tasks in a working-backward plan.
- How deep it goes
- Defines the hierarchy and work packages, but does not walk through constructing a complete WBS.
- Examples
- Shows a launch timeline with technical design, testing, launch, and retrospective tasks rather than a WBS diagram.
- What you can do after
- Build it from scratch by dividing project scope into work packages that can seed a working-backward plan.

Statistics Every Programmer Needs
A work breakdown structure is a tabular or visual decomposition of a project into component activities and their dependencies.
- How it is used
- Structures project work before scheduling, resource allocation, critical-path analysis, and broader project management.
- How deep it goes
- Defines activities and dependencies and demonstrates their tabular organization, but defers durations, other attributes, and critical-path calculations.
- Examples
- Uses an automated reporting tool with coded activities, descriptions, and dependencies from scope definition through deployment.
- What you can do after
- Build it from scratch by decomposing a project into activities and documenting the dependencies needed for subsequent planning.
