Information visualization is a process of transforming large quantity data and information, which are not inherently spatial, into a visual form that allows users to perceive visually the meaning of the information instead of using their cognitive powers to figure it out otherwise. The massive non-spatial data can be found in many business domains. Researchers have pointed out the potential dir...

The argumentative system, known to the decision-making, communications, knowledge creation, problem solving, and research methods literature, can be generalised to assist IS design. It has a deep philosophical basis, confronts the issue of uneven power relationships in stakeholders, does not assume objective knowledge, and encourages a learn-by-doing modular approach allowing rolling reflection...

Adaptive structuration theory (AST, DeSanctis and Poole 1994) describes how people come to understand and use a technology. In this paper we develop the idea of proactive structuration −− how social networking can be proactively managed in order to speed the comprehensive adaptation of a technology within a community of users. We examine two facets of proactive structuration – formal institutio...

Most research on Group Support Systems has focused on the study of the effects of features of the technology on processes and outcomes and has conceived of groups as mere collections of individuals (DeSanctis 1993; Kling 1991). However, as GSSs are moving from laboratories to organizational settings, a better understanding of both GSSs and groups is needed (Clapper and Prasad 1993). In this sen...

To build theory about how to achieve expected benefits from a system implementation, we conducted a longitudinal study of the implementation of an electronic health record (EHR) system at a multi-site clinic using grounded theory methods and a critical realist perspective. We developed a mid-level process theory of how clinics actualize affordances arising from the implementation of an EHR. In ...
