While most research in the area of human-information behavior has focused on a single dimension—either the psychological or the social—this case study demonstrated the importance of a multidimensional approach. The Cognitive Work Analysis framework guided this field study of one event of collaborative information retrieval (CIR) carried out by design engineers at Microsoft, including observatio...

The conceptual structure of most computer-based information systems reflects a dualism of technology. During the development phase, part of the work-domain related knowledge is formalized and encoded in the software, making it difficult for users to reflect on and use this knowledge. This dualism deters the interpretive flexibility of information systems. Dual Information Systems (DIS) are need...

Despite the increasing demand for information technology professionals in the job market, the number of undergraduates pursuing information systems (IS) degrees is declining. To improve student recruitment, it is important to understand the mechanisms by which students choose to pursue an IS major. This study focuses on the socio-cognitive factors that promote or inhibit the development of stud...

The flexibility of information systems (IS) is a topic of growing importance within IS analysis and design. IS have to cope with the increasing structural and behavioral complexity of environmental and business systems. Both increase the need for flexibility of a company’s IS. On the one hand, researchers and practitioners agree that IS flexibility is a crucial success factor for the viability ...

The "magical" number of 4 has been demonstrated to limit much of human information processing. The relevant evidence is briefly reviewed. It is proposed that the organization of processing structures is based on interconnected bidirectional pairs, with every element paired with every other one. The limit arises because of the large increase in links among elements required beyond structures of ...
