Explore use case modeling to structure functional requirements as actor–system interactions, linking data rules and user interfaces with practical, diagrammed scenarios.
Learn to construct use case descriptions that link to data and business rules, define triggers, preconditions, post-conditions, and both basic and alternative flows for system interactions.
Learn how preconditions determine when a use case can start by testing a state the system can verify, such as user authentication, while distinguishing preconditions from post-conditions and execution checks.
Define the basic flow as the happy path or main flow, a clear 80 percent sequence of actor and system interactions from trigger to post-condition that achieves the goal.
Explore alternative flows in use case documentation, detailing how to start and end deviations from the basic flow, capture reasons, and keep steps consistent for readability.
Define post-conditions for a use case as the system state after execution, with explicit steps for success or failure, linking preconditions and subsequent use cases.
Draft and refine the basic and alternate flow for time management use cases, define data elements and data dictionary references, and specify mandatory versus optional data, validation rules, and calculations.
Explore how to formalize system-driven business rules within use cases by linking steps to data dictionary elements and rule references, detailing approver determination and time-entry status workflows.
Learn practical tips for writing use cases with UI-agnostic verbs, consistent language, and technology-agnostic descriptions; manage alternative flows and document business rules effectively to support clear, reusable use cases.
This course is about a foundational technique of Business Analysis, use cases. For those of you who have taken our Business Analysis Simplified: Master These 10 Techniques to Deliver Requirements in Less Time, you will recognize use case modeling as one of the golden techniques. This is our second course on use case modeling. Our first course, Business Analysis Simplified - Model Use Case Diagram, focused on the use case diagram and the overall framework and why it's so successful. In this course, we are taking a deep dive into the use cases and explain how to document detailed requirements with use case technique.
So why use case modeling? In our opinion, it is the most important, useful, and efficient technique for analysis of system functional requirements. Once you learn this technique, you will not be able to approach a project without it and just like us for the last 15 years, will become a use case aficionado!
Here are our top three reasons why use case modeling is such a powerful technique:
As with all our courses, this course is focused on practice. You will work through a software development project as it's being delivered by a Business Analyst, named Laura, so that you can see use cases applied in a real-life scenario. You will also have an opportunity to practice use case technique in the assignment section of the course.
In this course, you will learn:
