Example from MIL-HDBK-881, which illustrates the first three levels of a typical aircraft system [1]. A work-breakdown structure (WBS) [2] in project management and systems engineering is a deliverable-oriented breakdown of a project into smaller components.
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 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.
For analytical purposes, the time required to produce a deliverable is estimated using several techniques. One method is to identify tasks needed to produce the deliverables documented in a work breakdown structure or WBS. The work effort for each task is estimated and those estimates are rolled up into the final deliverable estimate.

The statement of work should be directly linked to deliverables shown in the CDRL form. This is done by having each CDRL entry include reference to the SOW paragraph(s) that produces or uses the item, and the SOW text should be clear where it is discussing a deliverable by using the title or parenthesizing the item number (for example, "[A-001]").
In business and project management, a responsibility assignment matrix [1] (RAM), also known as RACI matrix [2] (/ ˈ r eɪ s i /; responsible, accountable, consulted, and informed) [3] [4] or linear responsibility chart [5] (LRC), is a model that describes the participation by various roles in completing tasks or deliverables [4] for a project or business process.
Work (1) is the amount of effort applied to produce a deliverable or to accomplish a task, (2) is everything required or supplied to complete a construction project. Work breakdown structure (WBS) - a deliverable oriented decomposition of a project into smaller components. It defines and groups a project's discrete work elements in a way that ...
