Value breakdown structure

A value breakdown structure (VBS) is a project management technique introduced by Stephen Devaux as part of the total project control (TPC) approach to project and program value analysis. The concept has similarities with the deliverable-oriented work breakdown structure (WBS) decomposition which is used in project management and systems engineering to break down a project into smaller components in a tree structure that represents how the work of the project will create the components of the final product.
