Chapter 5 - The design process
- Software engineering provides a means of understanding the structure of the design process, and that process can be assessed for its effectiveness in interactive system design.
- Design rules in the form of standards and guidelines provide direction for design, in both general and more concrete terms, in order to enhance the interactive properties of the system.
- Usability engineering promotes the use of explicit criteria to judge the success of a product in terms of its usability.
- Iterative design practices work to incorporate crucial customer feedback early in the design process to inform critical decisions which affect usability.
- Design involves making many decisions among numerous alternatives. Design rationale provides an explicit means of recording those design decisions and the context in which the decisions were made.
