Work Breakdown Structure Component

A distinct item (node) in the work breakdown structure that can appear at any level of the hierarchy.

Key Points

  • Exists at any level of the WBS, from high-level summary to lowest-level detail.
  • Can be a parent (summary) element or a leaf element such as a work package.
  • Should have a clear description and a unique identifier to support scope control.
  • Represents deliverable-oriented scope, not time-based activities or resources.

Example

In a building project, "Electrical System" at level 2, "Lighting" at level 3, and "First-Floor Lighting" at level 4 are each WBS components. Any of these entries, regardless of level, is considered a component.

PMP Example Question

Which statement best describes a Work Breakdown Structure Component?

  1. An element at any level within the WBS, including summary elements and work packages
  2. A scheduled task with durations and assigned resources
  3. A project calendar constraint used for estimating
  4. A discrete risk event that may impact scope

Correct Answer: A — An element at any level within the WBS

Explanation: A WBS component is any entry in the WBS hierarchy. Activities, calendars, and risks are different project artifacts.
