Developing Requirements for IT Systems with Use Cases

Improve customer satisfaction and product delivery by applying techniques from this use case based IT requirements development course. With this use case training, you will understand the difference between user requirements vs system requirements, and gain the skills to capture software and IT business needs and requirements. You will also write use cases to specify software requirements, draw UML diagrams to model the system, create the data and interface models, and develop an IT requirements document.

Learning Objectives

You Will Learn How To

  • Develop requirements for IT and software-intensive systems
  • Build a use case based requirements model
  • Write use cases 
  • Model user interfaces using mock-ups and a data model
