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.
Project accounting is a type of managerial accounting oriented toward the goals of project management and delivery.It involves tracking, reporting, and analyzing financial results and implications, [1] and sometimes the creation of financial reports designed to track the financial progress of projects; the information generated by this analysis is used to aid project management.
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] Beside WBS for project scope ...
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 ...
In large projects, establishing control accounts is the primary method of delegating responsibility and authority to various parts of the performing organization. Control accounts are cells of a responsibility assignment (RACI) matrix, which is the intersection of the project WBS and the organizational breakdown structure (OBS). Control ...
Project plan – is a formal, approved document used to guide both project execution and project control. The primary uses of the project plan are to document planning assumptions and decisions, facilitate communication among stakeholders, and document approved scope, cost, and schedule baselines. A project plan may be summary or detailed. [10]
Before a project schedule can be created, the schedule maker should have a work breakdown structure (WBS), an effort estimate for each task, and a resource list with availability for each resource. If these components for the schedule are not available, they can be created with a consensus-driven estimation method like Wideband Delphi. [5]
The GBS is the culmination of three concepts: the hierarchical relationship of product development, the work breakdown structure and requirements traceability.. The concept of a hierarchical relationship among objectives in product development was identified by Joseph M. Juran in Juran's Quality Control Handbook [2] where he states in section 2.2, subsection Hierarchy of Product Features ...
