Guide on Create Work Breakdown Structure (WBS)

What is WBS?
WBS, or Work Breakdown Structure, is a hierarchical and incremental decomposition of the project into phases, deliverables, and work packages. It is a critical project management tool that breaks the project work into more manageable sections.

Why is it Important?
WBS helps in clearly defining the project's scope by breaking down its overall mission into a cohesive set of synchronous, increasingly specific tasks. It provides a clear vision of what has to be delivered which leads to better understanding and accuracy in project estimates.

How Does WBS work?
WBS starts at the highest level with the project itself and then successively breaks down the project into major deliverable or project phases. Each phase is then further divided into sub-tasks, continuing to break down until each work package contains a group of tasks that can be assigned, controlled, and tracked.

Exam Tips: Answering Questions on Create WBS
Understand the concept thoroughly before attempting to answer. Remember, WBS is not a project schedule or a detailed plan of tasks, but a decomposition of the scope. Make sure to understand that WBS works on the '100% rule', which means that the WBS includes 100% of the work defined by the project scope and captures all deliverables. Also, real-world examples often help in understanding the concept better.

Create Work Breakdown Structure (WBS) practice test

The Work Breakdown Structure (WBS) is a hierarchical decomposition of the project scope into smaller, manageable components called work packages. It is a graphical representation that shows how the project deliverables are organized into a hierarchy. The WBS serves as a foundation for project planning, estimating, scheduling, and control activities. Each work package represents a specific portion of the project scope and includes the activities, resources, and timelines required to deliver it. The creation of the WBS involves breaking down the project scope into smaller, manageable pieces and assigning responsibilities and resources to each work package. Outputs from this process include a WBS dictionary, which provides detailed information about each WBS element, and the Scope Baseline, which is a combination of the project scope statement, the WBS, and the WBS dictionary.
