What is work breakdown structure in a construction project?
A work – breakdown structure ( WBS ) 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 deliverable that organizes the team’s work into manageable sections.
What is work breakdown structure in project management PDF?
A project work breakdown structure ( WBS ) is a deliverable or product-oriented grouping of project work elements shown in graphical display to organize and subdivide the total work scope of a project . The WBS is a particularly important project tool.
How do you create a construction WBS?
How to Create a WBS : The High-Level View Determine and describe the project statement. Highlight all the necessary phases of the project. Create and list the deliverables (as well as how success will be measured) Divide the deliverables into manageable tasks.
What are the 3 levels of work breakdown structure?
The WBS contains 100% of all the work in the project. At the top level is the project ultimate goal, the second level contains the project objectives, the third level has the project outputs and the fourth level with activities.
What is a WBS element?
WBS Element means Work Breakdown Structure Element . This is a master data used in the Project Systems module. Several WBS elements are grouped together to form a Project. Like other cost collectors like Cost Centers, Internal Orders, etc. the WBS element is a cost collector.
What are the different types of WBS?
The Project Management Institute (PMI) Project Management Book of Knowledge (PMBOK) defines the Work Breakdown Structure as a “deliverable oriented hierarchical decomposition of the work to be executed by the project team.” There are two types of WBS : 1) Deliverable-Based and 2) Phase-Based.
What is WBS example?
For example , here’s a WBS example for an aircraft system: Thus, you might have one group responsible for building an aircraft. Within this group, you might have one team focused on building the airframe, another on creating a propulsion system, and so on. It’s common to have three levels of decomposition in the WBS .
Why Work Breakdown Structure is important?
The benefits of creating a WBS include: it defines and organizes the work required. it facilitates the quick development of a schedule by allocating effort estimates to specific sections of the WBS . it can be used to identify potential scope risks if it has a branch that is not well defined.
What stage should WBS be prepared?
The project team prepares the WBS as the first step of the planning process as soon as a SMART objective is determined and the requirements of the party commissioning the project and expectations of the project client (or other important stakeholders) are known.
What makes a good WBS?
A good WBS should exhibit the following characteristics: Definable—can be described and easily understood by project participants. Manageable—a meaningful unit of work where specific responsibility and authority can be assigned to a responsible individual.
How detailed should a WBS be?
Generally speaking, a WBS should include about three levels of detail. Some branches of the WBS will be more subdivided than others, but if most branches have about three levels, the scope of your project and the level of detail in your WBS are about right.
Does every project need a WBS?
Every project has a WBS , just like they all have schedules and budgets. The WBS is the major input into the creation of the project schedule, budget, and risk plan. The more you involve your team in the creation of the WBS , the more they will understand the scope of the project and their role in its delivery.
What is cost breakdown structure?
A Cost Breakdown Structure (CBS) is a breakdown or hierarchical representation of the various costs in a project. The Cost Breakdown Structure represents the costs of the components in the Work Breakdown Structure (WBS).
What is the lowest level of WBS called?
work package level
