The Work Breakdown Structure and Project Estimation


Chapter 6 focuses on developing the work breakdown structure, as well as on introducing a number of project estimation approaches, tools, and techniques. After studying this chapter, you should understand and be able to:

  • Develop a work breakdown structure.
  • Describe the difference between a deliverable and a milestone.
  • Describe and apply several project estimation methods. These include the Delphi technique, time boxing, top-down estimation, and bottom-up estimation.
  • Describe and apply several software engineering estimation approaches. These include lines of code (LOC), function point analysis, COCOMO, and heuristics.
