ABSTRACT
Building information technology (IT) systems is best done by following a user-centered design approach. The core of such an approach is studying, understanding, and meeting the needs of the end users. In addition, user interaction with IT systems is subject to characteristics and limitations imposed by the human information processing system. Consequently, designers of IT systems should have a good understanding and knowledge of the following:
O The human information processing system. O The target audience for the IT system. O The users’ jobs and tasks. O The users’ knowledge and experience. O The physical and cultural characteristics of the
target audience. O The users’ physical environment.
