Beginning C# 2008 Objects: From Concept to Code

9.6. Summary

In this chapter, you learned the following:

• Use case analysis is a simple yet powerful technique for specifying the functional requirements for a system more precisely and completely.

• Use cases are based upon the goal-oriented functional requirements for a system.

• Use cases are used to describe:

  • The desired behavior/functionality of the system to be built

  • The external users or systems (known as actors) who avail themselves of these services

  • The interactions between the two

• The elements that don't belong in a use case (for example, technical requirements).
