Course 121:
Advanced Use Case Modeling for Business Analysts

(2 days)

 

Course Description

The use case is a method for documenting the behavior between the user of a system and the system. Use cases have been in the software development lexicon for twenty years since introduced by Ivar Jacobson in the late 1980s. They were originally intended as aides to software design in object-oriented approaches. Now the method is used throughout the Solution Development Life Cycle from elicitation to test case specification, and is applied to structured, as well as object-oriented software development approaches.

This course identifies how business analysts can apply use cases to the processes of defining the problem domain through elicitation, analyzing the problem, defining the solution, and confirming the validity and usability of the solution.

Learning Objectives

  • Apply the use case method to define the problem domain and discover the conditions that cause problems in the business process
  • Employ use cases in the analysis of requirements and information to create a solution to the business problem
  • Translate use cases into requirements

Who Should Attend

Business analysts, software developers, business users, product owners, project managers, and anyone else with an interest in understanding how to employ use cases to solve business problems.

Prerequisites

Completion of basic business analyst courses such as ROI Course 103: Roles, Responsibilities, and Processes of the Business Analyst.
