Cognitive design is a systems approach to designing a human-computer interface that draws from a combination of the behavioral sciences, software engineering, and computer science to design an expandable system that is useful and easy to use. It is a critical, up-front part of the design process and provides the focus for a multi-disciplinary approach to user-centered design. This paper reviews the various phases of cognitive design, as well as how the nature of the web industry often requires the process to be modified. A case study is presented to illustrate how the design process can be adapted and still follow sound cognitive design principles.
