This is typically done in a hierarchical arrangement called a work breakdown structure ( WBS ) although the simplest projects may use a simple list of tasks.

As in the lightweight implementation, the project manager must define the work comprehensively, typically in a WBS hierarchy.

His work is the forerunner to modern project management tools including work breakdown structure ( WBS ) and resource allocation.

The work breakdown structure ( WBS ) is a tree structure that shows a subdivision of effort required to achieve an objective — for example a program, project, and contract.

A work breakdown structure ( WBS ), in project management and systems engineering, is a deliverable oriented decomposition of a project into smaller components.

WBS is a hierarchical decomposition of the project into phases, deliverables and work packages.

In a project or contract, the WBS is developed by starting with the end objective and successively subdividing it into manageable components in terms of size, duration, and responsibility ( e. g., systems, subsystems, components, tasks, subtasks, and work packages ) which include all steps necessary to achieve the objective.

The WBS is organised around the primary products of the project ( or planned outcomes ) instead of the work needed to produce the products ( planned actions ).

: The 100 % rule states that the WBS includes 100 % of the work defined by the project scope and captures all deliverables – internal, external, interim – in terms of the work to be completed, including project management.

The rule applies at all levels within the hierarchy: the sum of the work at the “ child ” level must equal 100 % of the work represented by the “ parent ” and the WBS should not include any work that falls outside the actual scope of the project, that is, it cannot include more than 100 % of the work … It is important to remember that the 100 % rule also applies to the activity level.

If the work breakdown structure designer attempts to capture any action-oriented details in the WBS, he will likely include either too many actions or too few actions.

A question to be answered in determining the duration of activities necessary to produce a deliverable defined by the WBS is when to stop dividing work into smaller elements.

At the juncture of the WBS element and organization unit, control accounts and work packages are established and performance is planned, measured, recorded, and controlled.

At WBS Level 1 it shows 100 units of work as the total scope of a project to design and build a custom bicycle.

* A WBS is not an exhaustive list of work.

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.

Gantt charts have become a common technique for representing the phases and activities of a project work breakdown structure ( WBS ), so they can be understood by a wide audience all over the world.

His work is the forerunner to many modern project management tools including the work breakdown structure ( WBS ) and resource allocation.

The WBS Pens have gone to the Calder Cup Final three times in their twelve-year existence, most recently in 2008 by way of beating the Portland Pirates in a seven-game series in the Eastern Conference finals ; the Penguins took game seven by a score of 3-2 after being down in the series three games to two.

If the WBS element names are ambiguous, a WBS dictionary can help clarify the distinctions between WBS elements.

Applying this rule of thumb, one can apply " common sense " when creating the duration of a single activity or group of activities necessary to produce a deliverable defined by the WBS.

WBS design can be supported by software ( e. g. a spreadsheet ) to allow automatic rolling up of point values.

Instead the WBS should be fully defined to follow the 100 % Rule, then the project schedule can be designed.

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.

In either case, it is important that the WBS or list be comprehensive.

The WBS may be hardware -, product -, service -, or process-oriented ( see an example in a NASA reporting structure ( 2001 )).

A coding scheme also helps WBS elements to be recognized in any written context.

* A WBS is not an organizational hierarchy, although it may be used when assigning responsibilities.

To manage and control any SDLC initiative, each project will be required to establish some degree of a Work Breakdown Structure ( WBS ) to capture and schedule the work necessary to complete the project.

The WBS and all programmatic material should be kept in the “ project description ” section of the project notebook.

There are some key areas that must be defined in the WBS as part of the SDLC policy.

The following diagram describes three key areas that will be addressed in the WBS in a manner established by the project manager.

WBS is one of only 3 UK business schools to be awarded the top five-star ( 5 *) research rating by the Higher Education Funding Council for England ( HEFCE ), the others being London Business School and Lancaster's School of Management.

There are several heuristics or " rules of thumb " used when determining the appropriate duration of an activity or group of activities necessary to produce a specific deliverable defined by the WBS.

For example 1. 1. 2 Propulsion ( in the example below ) identifies this item as a Level 3 WBS element, since there are three numbers separated by a decimal point.

Supporters of product based planning suggest that this overcomes difficulties that arise from assumptions about what to do and how to do it by focusing instead on the goals and objectives of the project-an oft-quoted analogy is that PBS defines where you want to go, the WBS tells you how to get there.

Williams syndrome ( WS or WMS ; also Williams – Beuren syndrome or WBS ) is a rare neurodevelopmental disorder characterized by a distinctive, " elfin " facial appearance, along with a low nasal bridge, an unusually cheerful demeanor and ease with strangers ; developmental delay coupled with strong language skills ; and cardiovascular problems, such as supravalvular aortic stenosis and transient hypercalcaemia.

The most common series was the P2, followed by the WBS 70. the WHH GT 18, and Q3A.

Opstellen over criminaliteit & rechtshandhaving " (" Derailed, Essays about criminality and the law ") which was published by the WBS.

een cultuurpolitieke benadering van de Ruimtelijke Ordening " (" Land in sight, a culture-political approach to spatial planning ") together with Maarten Hajer, which was published by the WBS.

A WBS also provides the necessary framework for detailed cost estimating and control along with providing guidance for schedule development and control.

This standard established top-level templates for common defense materiel items along with associated descriptions ( WBS dictionary ) for their elements.

The WBS Dictionary describes each component of the WBS with milestones, deliverables, activities, scope, and sometimes dates, resources, costs, quality.

A WBS task may rely on one or more activities ( e. g. software engineering, systems engineering ) and may require close coordination with other tasks, either internal or external to the project.

The matrix is typically created with a vertical axis ( left-hand column ) of tasks ( e. g., from a work breakdown structure WBS ) or deliverables ( e. g., from a product breakdown structure PBS ), and a horizontal axis ( top row ) of roles ( e. g., from an organizational chart ) – as illustrated in the image of an example responsibility assignment ( or RACI ) matrix.

Since 1996 she was an editor of De Helling, a political magazine, linked to GroenLinks ; in the same year she started combining her work at the WBS with a position at De Balie, a well-known Dutch political-cultural centre.

It is also notable that very early European-Spec LHD M5s had VINs that started with " WBA " instead of the " WBS " designation to indicate BMW Motorsport.

WBS graduates have a good reputations amongst employers, with a Guardian survey rating WBS graduates the most employable in the UK.
