Use Case Essentials
(course code BANU1)


Use cases are a highly effective tool for gathering requirements for software development. There is confusion in the application of use cases, and their most effective usage. Our course demystifies use cases by translating their theory into practice. It helps participants learn the needed concepts in business terms and by putting those concepts into direct application. Add to your requirements-gathering repertoire and set the stage for later translation of requirements into software-friendly formats. The course covers the fundamentals and reinforces them with several in-depth workshops using a comprehensive case study. Leave class with the confidence to gather requirements using use case scenarios and activity diagrams. Participants will gain new skills and confidence that they can gather more complete and thorough requirements.

Course Objectives

By the end of this short course, participants will be able to:

  • Define the major components of use case models using the Unified Modeling Language (UML):
    • Actors;
    • Use cases;
    • Use case diagram;
    • Use case flow of events.
  • Develop a use case diagram to communicate the system scope;
  • Describe use cases with a narrative flow of events;
  • Develop primary path scenarios to describe the routine processing;
  • Document alternate paths for exceptions;
  • Learn how Activity Diagrams differ from Process Maps and the advantages of using them;
  • Develop Activity Diagrams to chart the scenarios;
  • Describe generalization, extend and include relationships.
