Work Breakdown Structure (WBS) is a way of grouping project elements based on deliverables; it outlines and defines the entire scope of work for a project. Each level down represents a more detailed definition of the project’s tasks. Creating a WBS code for a project is one of the most fundamental tasks in project management, and it is also extremely important.
