This paper examines the relationship between the utilization of Electronic Approval System(EAS) and task characteristics. More and more organizations are adopting EAS in order to support organizational decision making with groupware in Korea. This paper views EAS as organizational communication medium, investigates factors which influence EAS‘s use from media richness theory and shows suitable EAS functions for equivocality resolution and uncertainty reduction.
The data were collected from interviewing system managers of the five groupware implementation sites and by gathering archival documents electronically approved through EAS. Results show that most organizations use EAS only for documents with low equivocality and low uncertainty. For increasing utilization of EAS for more critical and unstructured tasks, current EAS should have additional functionalities such as video-conferencing and database access.
