Define 'work breakdown structure' (WBS).

A work breakdown structure (WBS) is fundamentally a hierarchical decomposition of a project into smaller, more manageable components. This breakdown allows project managers and team members to systematically organize and define the total scope of the project. By breaking down the project into smaller parts, it becomes easier to estimate costs, allocate resources, assign tasks, and monitor progress.

The creation of a WBS helps in clarifying project deliverables and ensures that all elements required for project completion are identified. This structured approach increases the chances of project success by facilitating better planning and control throughout the project lifecycle.

Other options do not accurately describe a work breakdown structure. For instance, while time-tracking tools and visual representations of timelines are valuable project management tools, they serve different purposes. A document listing stakeholders is also essential, but it focuses on people and roles rather than project structure and tasks, which is the primary focus of a WBS.
