The WBS number represents the task’s level in the hierarchy. The EAC of the summary tasks is also recalculated from the leaf nodes. an approved preliminary or critical design review). In this view, the actual cost that has been spent against a task to date is compared to the planned cost for the task. This article is a compilation of 22 professional work breakdown structure templates in word, exce, pdf & visio formats. You can create a WBS template from the WBS of an existing project, so that knowledge and best practices that you gathered during the planning of that project can be reused on similar projects in the future. It is widely used in the area of project management to breakdown … The costs are summarized by date. You can’t modify the cost estimation for a summary or container task. If you increase or decrease hours on the labor cost estimate, the schedule for the task is automatically recalculated. This ambiguity could result in duplicated work or miscommunications about responsibility and authority. A work breakdown structure (WBS) is a description of the work that will be done for a project. In your work breakdown structure, you can add: The sequence of tasks in a hierarchy. The Cost tracking view displays the tracking of cost consumption for a task. A Work Breakdown Structure WBS proposes a graphical nature that helps project managers predict results … It is a hierarchical description of the work that must be done to complete the deliverables of a project. The cost estimation for a summary task is equal to the sum of the cost estimation of its leaf node tasks. A coding scheme also helps WBS elements to be recognized in any written context and allows for mapping to the WBS Dictionary. Currently, the system  for WBS tracking doesn’t have data structures to store historic progress percentages on each task. In 1987, the Project Management Institute (PMI) documented the expansion of these techniques across non-defense organizations. This term was created in the USA in 1993. For new product development projects, the most common technique to ensure an outcome-oriented WBS is to use a product breakdown structure. Therefore, earned value can be reported only as of the time that the cube is processed. a spreadsheet) to allow automatic rolling up of point values. This feature can cause significant modifications to the WBS. These smaller parts are then broken down further until a single team member can be made in charge of it. These larger elements could be further subdivided using the progressive elaboration technique described above. The earned value chart component shows the time-phased values of planned value and actual cost. Therefore, the project is under budget. [9] This guide was endorsed by the Secretary of Defense for adoption by all services. Please feel free to take a screenshot of the examples or open the WBS chart within MindView. It organizes and defines the total scope of the project. [18] For example, 1.1.2 Propulsion (in the example below) identifies this item as a Level 3 WBS element, since there are three numbers separated by two decimal points. Company owners and project managers use the Work Breakdown Structure (WBS) to make complex projects more manageable. For items, cost and sales price are added by default from the item or trade agreements on the Released products list page in Product information management. Therefore, planned value is the rate at which project planners thought work would be completed on the project. ", A work-breakdown structure element may be a product, data, service, or any combination thereof. Usually, the project managers use this method for simplifying the project execution. For example, shipbuilding for the U.S. Navy must respect that the nautical terms and their hierarchy structure put into MIL-STD[26] are embedded in Naval Architecture[27] and that matching Navy offices and procedures have been built to match this naval architecture structure, so any significant change of WBS element numbering or naming in the hierarchy would be unacceptable. If the actual cost that is spent for a period is more than the earned value, more money was spent than earned. [7] While the term "work breakdown structure" was not used, this first implementation of PERT did organize the tasks into product-oriented categories. Occasionally, the project manager or another persona that is tracking the progress of a project will have to revise the original estimates on a task. A work breakdown structure is a key project deliverable that organizes the team's work into manageable sections. Because earned value uses the cost price as the multiplier, earned value indicates the cost of the work that is done on a project. Cost variance The purpose for the numbering is to provide a consistent approach to identifying and managing the WBS across like systems regardless of vendor or service. Each level of the WBS is a smaller piece than the level above. Since the planned outcomes are the desired ends of the project, they form a relatively stable set of categories in which the costs of the planned actions needed to achieve them can be collected. [14] It has been defined as follows: Mutually exclusive: In addition to the 100% rule, it is important that there is no overlap in scope definition between different elements of a work breakdown structure. At WBS Level 1 it shows 100 units of work as the total scope of a project to design and build a custom bicycle. It organizes and defines the total scope of the project. Fixing all scheduling errors After you create a template, you can import it into a new project’s WBS under the root node, or under any task in the project’s WBS. Actual cost The Project Management Body of Knowledge (PMBOK) Guide provides an overview of the WBS concept, while the "Practice Standard for Work Breakdown Structures" is comparable to the DoD standard, but is intended for more general application.[13]. The effort, cost, and dates of the task’s previous parent task are recalculated to exclude that task. The EAC, CTC, and percentage of cost consumed on the task are recalculated. Similarly, responsibility based structure arranges project activities based on responsibilities while phase-based structure streamlines project … However, cost revisions don’t affect the values in the Effort tracking view, because the cost by transaction type (labor, material, or expense) or project category isn’t revised. At WBS Level 2, the 100 units are divided into seven elements. The three largest elements of WBS Level 2 are further subdivided at Level 3. The project root task is the top-level summary task for a project. For tasks that are under the first level, a numbering scheme of 1.1, 1.2, 1.3, and so on is used. Errors are corrected in the following order: As was mentioned earlier in this document, you enter the cost estimation for each leaf node task by using the Estimated costs and revenues tab in the lower pane of the Work breakdown structure page.
