develop a WBS for a local stage play. Be sure to identify the deliverables and organizational units (people) responsible. How would you code your system? Give an example of the work packages in one of your cost accounts. Develop a corresponding OBS which identifies who is responsible for what.
Expert Answer
A work breakdown structure (WBS), 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 deliverable that organizes the team’s work into manageable sections. The Project Management Body of Knowledge (PMBOK 5) defines the work breakdown structure as a “A hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables.”
A work breakdown structure element may be a product, data, service, or any combination thereof. A WBS also provides the necessary framework for detailed cost estimating and control along with providing guidance for schedule development and control
. The WBS avoids having the project driven by organization function or by a
finance system. The structure forces attention to realistic requirements of personnel, hardware, and budgets. Use
of the structure provides a powerful framework for project control that identifies deviations from plan, identifies
responsibility, and spots areas for improved performance. No welldeveloped project plan or control system is
possible without a disciplined, structured approach. The WBS, OBS, and cost account codes provide this
discipline. The WBS will serve as the database for developing the project network which establishes the timing of work, people, equipment, and costs.
PBS is often used for processbased projects with illdefined deliverables. In small projects
responsibility matrices may be used to clarify individual responsibility.
Clearly defining your project is the first and most important step in planning. The absence of a
clearly defined project plan consistently shows up as the major reason for project failures. Whether you use a
WBS, PBS, or responsibility matrix will depend primarily on the size and nature of your project. Whatever
method you use, definition of your project should be adequate to allow for good control as the project is being
implemented
