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.
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. This feeds into creation of the WBS, which identifies the tasks ...
The work breakdown structure (WBS) is a tree structure that shows a subdivision of the activities required to achieve an objective – for example a portfolio, program, project, and contract. The WBS may be hardware-, product-, service-, or process-oriented (see an example in a NASA reporting structure (2001)). [75]
In some cases, a geographic division may be preferred. Each descending (lower) level represents an increasingly detailed description of the resource until small enough to be used in conjunction with the work breakdown structure (WBS) to allow the work to be planned, monitored and controlled.
The product flow diagram (PFD) is a representation of the order by which a sequence of products is created according to product-based planning principles. It is related to the product breakdown structure (PBS). The product flow diagram is a prescribed activity of the PRINCE2 project management methodology which mandates the use of product-based ...
Implicit means that they are not included in the project network, but must be identified by looking at the resource requirements. Lack of search for an optimum solution—a "good enough" solution is enough because: As far as is known, there is no analytical method for finding an absolute optimum (i.e., having the overall shortest critical chain).
