Use Case Modelling
(course code BANM2)

Overview

Use cases provide a structured, industry-standard way of eliciting and documenting functional requirements. The process enhances communication between business analysts and business customers, and lays the foundation for user interface design and test case development. They also provide insights into data requirements, and help clients articulate their needs in ways other requirements activities can’t.

This course provides the right blend of knowledge and skills for people to understand and model use cases effectively. Attendees will learn where use cases are most effective, a step-by-step method for creating them, and numerous guidelines and tips to enhance creating them. Participants also receive a comprehensive Use Case template that can be readily used back on the job. For onsite presentation, a company’s own template can be easily incorporated into the course.

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):
  
  • Use case diagram;
  • Actors;
  • Use cases;
  • Interfaces;
  • 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 and exception paths for different scenarios;
• Develop Activity Diagrams to chart the scenarios of a use case;
• Diagram generalization, extend and include relationships;
• Leverage use cases to quickly create test cases;
• Develop user interfaces from use cases, and uncover hidden requirements;
• Create Class Diagrams from use cases.

Who Should Attend

This course is designed for business analysis, business experts, and systems analysts.

Prerequisites

Some basic understanding or exposure to process concepts.

This course is meant to be taken following either our Business Analysis Fundamentals or Managing Business Requirements courses, but can be taken independently if necessary.
