CHAPTER 1
Introduction to the Work Breakdown Structure

This chapter provides basic information about the work breakdown structure (WBS), including the background of the concept and its place and role in the project management process. Specifically, the chapter first discusses project management terms and definitions and explains why—on a very basic level—a work breakdown is needed. The chapter next illustrates where the WBS fits in the overall project management process and gives a history of the evolution of the WBS concept. Finally, the chapter briefly describes the role of the WBS in the private and public sectors.
