System Requirements Definition Using Use Cases Training Course - 1 Day

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 management is discussed. Understanding is tested with exercises based on a real-world project example either using a suitable use case modelling tool or on paper.

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 with at least 2 years experience. This course is not suitable for those seeking certification as a step towards a qualification. See the Certification Policy for a detailed discussion.

Course Logistics:

Course attendance is limited to 12 students. Courses start at 9.00am and finish at 5.00pm each day. Students normally use a computer for the exercises, but these can be performed on paper if required. For a discussion on using a use case modelling tool please see Modelling Tool Use on Courses. Printed course manuals for each student with copies of all presentations, exercises and solutions are provided.

On-Site (In-House) Courses:

The client is expected to provide an appropriate venue, refreshments, XGA/WXGA projector and screen, whiteboard or flipchart and at least one computer per two students loaded with a suitable use case modelling tool, unless exercises are to be performed on paper. 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. Students bring their own laptops for use on the course. Please see the Public BPMN and UML Training Courses in London page for details.

Pricing:

On-site (in-house) course pricing is available from the On-Site Course Price Calculator page. Public course pricing is available on the Public BPMN and UML Training Courses in London page. For consultancy pricing please see the On-Site Consultancy Price Calculator.
