Work Breakdown Structures: The Foundation for Project Management Excellence

The Work Breakdown Structure (WBS) has emerged as a foundational concept and tool in Project Management. It is an enabler that ensures clear definition and communication of project scope while performing a critical role as a monitoring and controlling tool. Created by the three experts who led the development of PMI's Practice Standard for Work Breakdown Structures, Second Edition, this much-needed text expands on what the standard covers and describes how to go about successfully implementing the WBS within the project life cycle, from initiation and planning through project closeout.

Filling the gap in the literature on the WBS, Work Breakdown Structures: The Foundation for Project Management Excellence gives the reader an understanding of:

• The background and key concepts of the WBS

• WBS core characteristics, decomposition, representations, and tools

• Project initiation and the WBS, including contracts, agreements, and Statements of Work (SOW)

• Deliverable-based and activity-based management

• Using the WBS as a basis for procurement and financial planning

• Quality, risk, resource, and communication planning with the WBS

• The WBS in the executing, monitoring, and controlling phases

• New concepts regarding the representation of project and program scope

• Verifying project closeout with the WBS

Using a real-life project as an example throughout the book, the authors show how the WBS first serves to document and collect information during the initiating and planning phases of a project. Then, during the executing phase, the authors demonstrate how the WBS transitions to an active role of project decision-support, serving as a reference and a source for control and measurement.

了解並應用有關工作分解結構的新概念

工作分解結構（WBS）已成為項目管理中的基礎概念和工具。它是一個使項目範圍清晰定義和溝通的工具，同時在監控和控制方面發揮關鍵作用。本書由三位領導PMI《工作分解結構實踐標準》第二版開發的專家撰寫，擴展了標準所涵蓋的內容，並描述了如何在項目生命週期中成功實施WBS，從啟動和規劃到項目結束。

填補了有關WBS的文獻空白，《工作分解結構：項目管理卓越的基礎》使讀者了解：

- WBS的背景和關鍵概念
- WBS的核心特徵、分解、表示和工具
- 項目啟動和WBS，包括合同、協議和工作聲明（SOW）
- 基於可交付成果和基於活動的管理
- 使用WBS作為採購和財務規劃的基礎
- 使用WBS進行質量、風險、資源和溝通規劃
- WBS在執行、監控和控制階段的應用
- 有關項目和計劃範圍表示的新概念
- 使用WBS驗證項目結束

本書通過一個真實項目的示例，展示了WBS在項目的啟動和規劃階段如何用於記錄和收集信息。然後，在執行階段，作者演示了WBS如何轉變為項目決策支持的積極角色，作為參考和控制和測量的來源。
