Course Overview
Use cases provide a structured, industry-standard way of eliciting and documenting visibly observable functional requirements from the point of view of the business. The process enhances communication between business analysts and stakeholders and helps the stakeholders articulate their needs in a way other elicitation techniques can’t. It also lays the foundation for user interface design and test case development. You will learn where use cases are most effective, a step-by-step method for creating them, and guidelines and tips to enhance them. This course provides the right blend of knowledge and skills for people to understand and model business use cases effectively.
Note: This course has been approved by PMI for 14 PDUs.
Who Should Attend
This course is intended for business analysts, systems analysts, project managers, product owners, and any project professional who develop software applications.
Course Objectives
- Leverage use cases to elicit stakeholder and functional requirements
- Define and model the major components of use case models using Unified Modeling Language (UML) notation
- Understand how to leverage use cases in a predictive or adaptive environment
- Identify the different types of actors and determine candidate use cases
- Develop a use case diagram to communicate system scope
- Describe Use Cases through a narrative flow of events (Primary, alternate, and exception paths) using a Use Case Template
- Diagram various use case relationships
- Develop an Activity Diagram to chart the scenarios of a Use Case
- Leverage use cases to quickly create test cases
- Develop user interface prototypes based on the use case to uncover additional requirements
