The use case technique is a widely used approach in capturing the functional requirements of software systems. Use cases provide an effective, sufficiently detailed and clear way to describe how software systems are used.
By investigating how the use cases are used at different stages of software development, it is possible to write them in ways that support those activities in better ways. Such written use cases streamline and drive the software development process resulting improved efficiency.
This comprehensive training teaches you how to write effective use cases. The use cases you write with that knowledge will be expressive, focused, clear, highly usable and effective during the different stages of software development including estimation, design, development, testing and verification.
At the end of the training, participants will be able to
- Write highly usable and effective use cases.
- Describe the use case technique as a requirements capturing mechanism.
- Use different styles of use cases to suit different contexts.
- Use well developed use case templates.
- Write use cases at a consistent level and re-organize multi-level uses cases.
- Draw UML use case diagrams.
- Identify system functionality reuse cases.
- Properly work with use case inclusion, extension and generalization mechanisms.
- Describe and practice the use case development process.
- Include relevant non-functional requirements in the use cases.
- Software development professionals working with requirements (Business Analysts, Software Engineers, Tech Leads, Project Managers, Architects)
- Enterprise Architects
- Project management professionals and consultants
- IT governance and assurance professionals
- IT managers involved in software development projects
- General familiarity with the software development process. No thorough knowledge is expected.
