Use Case Modeling



As a business analyst and as part of identifying and documentingrequirements, you must be able to explain how individuals will interact with anew or updated system. Use case modeling is a modern approach for describingsystem requirements by focusing on 'actors' to describe thatinteraction.

In this course, you will learn how to utilize use case modeling to documentfunctional requirements that can be understood and validated by all projectstakeholders, including technical staff and business stakeholders, increasingthe likelihood that stakeholder needs on a project are met.

Through hands-on activities and 75% of your class time spent practicing newskills, you will master creating use case models, including creating use casediagrams and descriptions to communicate functional requirements. You will learnthe theory and practice of creating use case flows to describe normal andexceptional usage scenarios and using advanced techniques to refine the use casemodel. You will learn how use cases can enhance your skills as a businessanalyst and help technical staff clearly understand the requirements of thebusiness. Leveraging the best practices of use case modeling on your nextproject will ensure that it is designed to requirements and that clientexpectations are met.

Students pursuing a university-recognized and/or accredited certificate in Canada or continuing education units in the US must attend at least 90% of class time, participate in class exercises and section-knowledge checks, and score at least 70% on an end-of-class, multiple-choice assessment.
