System Requirements Definition using Use Cases
Training Course - 1 Day
Download a pdf version of this page
This training course teaches business and system analysts how to produce a detailed outside-in model of computer system requirements using use cases within the context of a model-driven software development process. A strict best practice approach to writing effective use cases ensures that the results satisfy the needs of both non-technical and technical stakeholders. The gains that defining requirements with use cases brings to estimation, traceability, test development and project management is discussed. Understanding is tested and improved with exercises based on a real-world example on paper or using using a suitable case tool.
Delegates will learn
  • How to create a first cut overview of functional requirements with actors and use cases on a use case diagram
  • How to write an effective use case description in a way that satisfies both non-technical and technical stakeholders
  • How to specify the flow of events as a basic flow and alternate flows
  • How to restructure the use case diagram to handle complex relationships between use cases without bloating the use case model
  • How to integrate the use case model with non-functional requirements, data requirements, business rules and screen prototyping
  • How a use case driven approach to requirements gathering improves estimation, project planning, test development and traceability
Suitable for:
Business Analysts, System Analysts, Requirements Gatherers, Developers and Project Managers involved in the system requirements gathering process
On-Site Courses:
Training courses are delivered at the clients' site and attendance is limited to 12 students. Courses normally start at 9.30am on the first day and 9.00am on subsequent days. Courses normally finish at 5.00pm each day. The client is expected to provide an appropriate venue, equipment and refreshments. Required equipment includes an SVGA/XGA projector and screen, whiteboard or flipchart and at least one computer per two students loaded with a UML case tool. For a discussion on case tool use please see Case Tool Use on Courses. Printed course manuals for each student with copies of all presentations, exercises and solutions are provided. For a full discussion of on-site course issues please see On-Site Course Logistics.
Scheduled Public Courses:
This course is available as scheduled public training at our London Training Centre. Please see the Scheduled Public Courses page for details.
