The previous E-Book in this series explored the psychology of  Requirements Analysis (RA).  In this the final E-Book in this Fundamentals of Requirements Analysis series, I present a Work Breakdown Structure (WBS) for defining a set of requirements.  It follows from the course content presented throughout this program.  Although you already know that a WBS is a core component of any project management environment, you should also realize that a WBS is not a project plan.
