Use Case Modeling
In-person classes – 2 days / Virtual (Live online) and Anytime Learning – 4 sessions
Use cases provide a structured, industry-standard way of eliciting and documenting functional interaction 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 is easily incorporated into the course.
- Define the major components of use case models using the Unified Modeling Language (UML):
- Use case diagram
- Use case narratives
- Use case flow of events
- Develop a use case diagram to communicate the system scope.
- Describe use cases, using 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 to jump-start data requirements.
Pre-requisites: Experience related to software development is highly recommended.
Skill Level: Basic
This course is intended for IT professionals; business clients and project managers who want to develop software applications quickly and with minimal change.
PDUs/CDUs: 14 CEUs: 1.4
- Masters Certificate in Business Analysis
To help assimilate the tools and techniques learned, there is a mixture of individual and team exercises throughout the course. A lively role-play and case study help reinforce concepts learned. Students will need to be prepared for a high level of participation. Each participant will receive a comprehensive student guide complete with examples, workshop solutions, and a comprehensive Use Case template.
