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 precedence diagram method (PDM) is a tool for scheduling activities in a project plan.It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies.
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 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]
The project schedule is a calendar that links the tasks to be done with the resources that will do them. It is the core of the project plan used to show the organization how the work will be done, commit people to the project, determine resource needs, and used as a kind of checklist to make sure that every task necessary is performed.
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.
Compared to Microsoft Project, which it closely emulates, ProjectLibre has a similar user interface (UI) including a ribbon-style menu, and a similar approach to construction of a project plan: create an indented task list or work breakdown structure (WBS), set durations, create links (either by (a) mouse drag, (b) selection and then button ...
In a project network, a dependency is a link among a project's terminal elements. [citation needed]The A Guide to the Project Management Body of Knowledge (PMBOK Guide) does not define the term dependency, but refers for this term to a logical relationship, which in turn is defined as dependency between two activities, or between an activity and a milestone.
