Copyright John Wiley & Sons, Inc Chapter 2 Organizational and Business Context HCI: Developing Effective Organizational Information Systems Dov Te’eni Jane Carey Ping Zhang

Copyright John Wiley & Sons, Inc Why study HCI? To help make IS users more productive, To help IS professionals develop more usable and successful systems, To enhance organizational effectiveness, To provide researchers with cohesive and cumulative knowledge for theory building, and, To apply this theoretical knowledge to enhance real information systems.

Copyright John Wiley & Sons, Inc Organization of this chapter This chapter sets the stage for the study of human– computer interaction (HCI) in organizations. The levels of interaction (task, syntax, semantics, and lexical) help to organize the different sections of this chapter. Tasks are categorized as structured, semi-structured, or unstructured. We introduce the various levels of systems which are individual, work group, organizational, and inter- organizational. HCI as a means for overcoming human limitations.
