work breakdown structure

Do you struggle to fully define the scope of your project? The best place to start is a Work Breakdown Structure. A work-breakdown structure (WBS) breaks down a project into smaller deliverable components. It is a key project resource that organises the project into manageable sections. The more clearly the scope of the project is defined before the actual work begins, the more likely the success of the project. Using a standard approach ensures consistency across all of your projects and can be used for tendering, estimating, scheduling and controlling the project.
