Theoretical highlight 9: Systems Development - User-Centered Systems Development, User Interfaces and Prototypes
The purpose of this theoretical highlight is to describe the basics of user-centered systems design (UCSD), including both theoretical and practical aspects. Certain parts of the user-centered development project will be covered in more detail, for instance, how prototypes can be used in the development process.
The lecture covers
- Different types of systems development models
- The waterfall model versus experimental/iterative development
- User-centered systems development
- The role of the user in the development project
- Commercial development models
The above items are described in this pdf file
The Preece textbook (and the optional textbook by Gulliksen & Göransson (in Swedish)) provide comprehensive summaries of these issues. Please note that the slides presented in the PDF above are just a short summary of the chapters in Preece's textbook.

- Agile modelling provides an alternative approach to systems development. eXtreme Programming is probably the most well-known agile process.

- Understanding use case modelling
- Use-case zone
- Essential use cases - a variant of use cases with a usability focus.
