You Will Learn How To

  • Develop requirements for software-intensive systems using proven methodologies
  • Apply use cases to software development initiatives
  • Build a use case-based requirements model
  • Write user stories and brief, casual, fully developed use cases
  • Model user interface using mock-ups and develop a data model
  • Validate requirements, manage the changes and keep traceability

Course Benefits

Requirements gathering is the cornerstone of any software development project. In this course, you gain the knowledge and skills needed to capture software requirements using clearly defined processes. You learn to specify user and system requirements, match the process to the size of your project, and apply quality and consistency tests to the requirements model.

Who Should Attend

Those developing, leading, designing, testing or managing a requirements initiative for a software system. UML experience is not required. Those responsible for identifying user requirements in a nonsoftware development environment should take Course 315, "Developing User Requirements."

Extensive PC-based activities throughout the course immerse you in a realistic user requirements environment, providing practical experience in constructing a software requirements model. Activities include:
  • Capturing stakeholder input from video scenarios that put you at the meeting table
  • Modeling requirements with UML diagrams using a leading CASE tool
  • Capturing, structuring and refining use cases in a realistic simulated environment
  • Developing screen mock-ups with an interface simulation
  • Producing a UML requirements data model
  • Validating requirements using IEEE standard checklists
  • Performing inspections on real-world use case documents

"For the past 10 years, I have taught courses in colleges and universities, so the way that Learning Tree operates and presents its classes was a very different experience for me. I did not believe that you could learn something in a few days, but I believe it now. The class was highly professional, and the instructor was exceptional."
