What is WBS (work breakdown structure)?

    A work breakdown structure divides the project scope into smaller, manageable pieces, arranged as a hierarchy from the whole project down to individual work packages.

    Also written as WBS

    The WBS is the common structure that schedule, budget, progress and reporting hang from. When they share one structure, cost and schedule can be compared item by item.
