Practice Standard for Work Breakdown Structures – Third Edition

Work breakdown structures (WBS) are a key component in the project planning process, regardless of industry or discipline. The WBS organizes the project’s total scope while reflecting the work specified—helping practitioners standardize how they track projects and overcome large uncertainties when they arise.

As a comprehensive update to the Practice Standard for Work Breakdown Structures – Second Edition, the Third Edition applies the WBS to agile, iterative, predictive, and incremental project life cycles, while also exploring several different types of decomposition in practice today.
