A Work Breakdown Structure (WBS) in project management and systems engineering, a tool used to define the group and project work discrete elements (or tasks) in a way that helps the organization and scope of work to complete the project to define .

Work Breakdown Structure (WBS) is used to define work packages and

developing and maintaining cost and schedule for the project. The work is divided into

tasks, each manager, responsible institution, cost and schedule, technical

scope, and, where possible, a specific piece of geographical machine.

Is a complex project manageable by first breaking it down into individual components in a hierarchical structure, called the Work Breakdown Structure, or WBS. Such a structure defines the tasks can be run independently of the other tasks, the allocation of resources, allocation of responsibilities to facilitate, and measuring and monitoring the project.

Terminology for different levels

Each organization uses its own terminology for WBS components are categorized according to the level of the hierarchy. For example, some organizations refer to different levels and tasks, sub-tasks and work packages, as shown in the above sketch. Others use the terms degrees, admissions and activities.

Organization on the performance of the stages

The WBS can be organized around the performance of the stages of the project lifecycle. Higher in the general structure groups. The lowest level in the hierarchy often activities are performed by individuals, although the WBS deliverables stressed that it is not necessary to give the activities.

Level of Detail

A breakdown of the project into its component parts facilitates the allocation of resources and allocation of specific responsibilities. Be careful to the appropriate level of detail in making use of the WBS. On a very large, very high level of detail is likely to result in micro-management. The other major, the tasks that are too big to manage effectively. Tasks that define a period between days and months to work well for most projects.
