A work-breakdown structure (WBS) [2] in project management and systems engineering is a deliverable-oriented breakdown of a project into smaller components. A work breakdown structure is a key project management element that organizes the team's work into manageable sections.
Work breakdown structure (WBS) is a method and a kind of representation that defines a project and groups the project's discrete work elements in a way that helps organize and define the total work scope of the project. A Work breakdown structure element may be a product, data, a service, or any combination.
The IMP provides a better structure than either the Work Breakdown Structure (WBS) or Organizational Breakdown Structure (OBS) for measuring actual integrated master schedule (IMS) progress. [ 8 ] The primary objective of the IMP is a single plan that establishes the program or project fundamentals.

The PBS is identical in format to the work breakdown structure (WBS), but is a separate entity and is used at a different step in the planning process. The PBS precedes the WBS and focuses on cataloguing all the desired outputs (products) needed to achieve the goal of the project.
In project management, these are often project components visualised in hierarchical form: Goals breakdown structure ( GBS ) Organizational breakdown structure ( OBS ), Diagram showing organizational structure Pages displaying short descriptions of redirect targets
The concept is based on the Work Breakdown Structure (WBS) popular in the project management discipline. Like the WBS, project goals exhibit a hierarchical structure. The highest-level defines the overall goal or mission for the project. The next level down sets the goals the organization intends to achieve from the project.
The precedence diagram method (PDM) is a tool for scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies. It is also called the activity-on-node (AON) method.
