A work breakdown structure is a hierarchical decomposition of the project into smaller, manageable components. This structured segregation allows the team to understand their role in each project phase and work collaboratively and effectively to meet critical milestones and deadlines.
Typically, WBS serves as a reference point for managers to gauge progress throughout the project lifecycle. Additionally, it helps identify and address potential bottlenecks early in the project before they escalate and hinder the workflow, resulting in unexpected delays.
