How do you structure a WBS?
Tips for making a work breakdown structure
- The 100% rule. The work represented by your WBS must include 100% of the work necessary to complete the overarching goal without including any extraneous or unrelated work.
- Mutually exclusive.
- Outcomes, not actions.
- The 8/80 rule.
- Three levels.
- Make assignments.
What is WBS hierarchy?
The WBS is a hierarchy of all project work, it is a vertical breakdown, moving from the project goal to the tasks or subtasks. This decomposition process allows a good level of confidence in estimating the final project schedule and budget. It shows all the work that needs to be accomplished.
What is Level 3 in WBS?
Level 3 items are key activities required to produce the Level 2 deliverables. Additional levels are used depending upon the magnitude of the deliverables and the level of detail required to reliably estimate cost and schedule. In the deliverable-oriented WBS, all deliverables are identified, and all work is included.
How many levels are in WBS?
It’s common to have three levels of decomposition in the WBS. You might have a fourth and even a fifth level in case of extremely complex projects. For most projects, however, three levels will suffice.
How to create a Work Breakdown Structure ( WBS )?
You can create a WBS using different formats like text-based work breakdown structures, tabular structures, or more visual ones like flowcharts. Once it is complete, share it with the team.
What are the different types of WBS structures?
A deliverable-based WBS identifies the project’s deliverables and scope, while the phase-based WBS displays the final deliverable on top, with the level below showing the five phases of a project (initiation, planning, execution, control and closeout). There are a few uncommon types of work breakdown structures as well:
How is WBS used in project management software?
Project managers make use of project management software to lay out and execute a work breakdown structure. When used in combination with a Gantt chart that incorporates WBS hierarchies, project management software can be especially effective for planning, scheduling and executing projects.
What do you need to know about a WBS?
Making a WBS is the first step in developing a project schedule. It defines all the work that needs to be completed (and in what order) to achieve the goals and objectives of the project.
