Integrating Human-Computer Interaction Development into SDLC: A Methodology

Incorporating a human computer interaction (HCI) perspective into the systems development life cycle (SDLC) is critical to information systems (IS) success and in turn to the success of businesses. However, modern SDLC models are based more on organizational needs than human needs. The human interaction aspect of an information system is considered far too little (only the screen interface) and far too late in the IS development process (only at the design stage). Thus there is often a gap between satisfying organizational needs and supporting and enriching human users as they use the system for their tasks. This problem can be fixed by carefully integrating HCI development into the SDLC process to achieve a truly human-centered IS development approach. This tutorial presents a methodology for such human-centered IS development where human requirements for the whole system are emphasized. An example of applying such methodology is used to illustrate the important concepts and techniques.
