Giant strides in information technology at the turn of the century may have unleashed unreachable goals. With the invention of groupware, people expect to communicate easily with each other and accomplish difficult work even though they are remotely located or rarely overlap in time. Major corporations launch global teams, expecting that technology will make “virtual collocation” possible. Federal research money encourages global science through the establishment of “collaboratories. ” We review over 10 years of field and laboratory investigations of collocated and noncollocated synchronous group collaborations. In particular, we compare collocated work with remote work as it is possible today and comment on the promise of remote work tomorrow. We focus on the sociotechnical conditions required for effective distance work and bring together the results with four key concepts: common ground, coupling of work, collaboration readiness, and collaboration technology readiness. Groups with high common ground and loosely coupled work, with readiness both for collaboration

Over the last 10 years, Computer-Supported Cooperative Work (CSCW) has identified a base set of findings. These findings are taken almost as assumptions within the field. In summary, they argue that human activity is highly flexible, nuanced, and contextualized and that computational entities such as information transfer, roles, and policies need to be similarly flexible, nuanced, and contextualized. However, current systems cannot fully support the social world uncovered by these findings. This paper argues that there is an inherent gap between the social requirements of CSCW and its technical mechanisms. The social-technical gap is the divide between what we know we must support socially and what we can support technically. Exploring, understanding, and hopefully ameliorating this social-technical gap is the central challenge for CSCW as a field and one of the central problems for HCI. Indeed, merely attesting the continued centrality of this gap could be one of the important intellectual contributions of CSCW. This paper also argues that the challenge of the social-technical gap creates an opportunity to refocus CSCW as a Simonian science of the artificial.

A design rationale (DR) is a representation of the reasoning behind the design of an artifact. In recent years, the use of semiformal notations for structuring arguments about design decisions has attracted much interest within the human-computer interaction and software engineering communities, leading to a number of DR notations and support environments. This paper examines two foundational claims made by argumentation-based DR approaches: that expressing DR as argumentation is useful, and that designers can use such notations. The conceptual and empirical basis for these claims is examined, firstly by surveying relevant literature on the use of argumentation in non-design contexts (from which current DR efforts draw much inspiration), and secondly, by surveying DR work. Evidence is classified according to the research contribution it makes, the kind of data on which claims are based (anecdotal or experimental), the extent to which the claims made are substantiated, and whether or not the users of the approach were also the researchers. In the survey, a trend towards tightly integrating DR with other design representations is noted, but it is argued that taken too far, this may result in the loss of the original vision of argumentative

To understand the economic value of computers, one must broaden the traditional definition of both the technology and its effects. Case studies and firm-level econometric evidence suggest that: 1) organizational “investments ” have a large influence on the value of IT investments; and 2) the benefits of IT investment are often intangible and disproportionately difficult to measure. Our analysis suggests that the link between IT and increased productivity emerged well before the recent surge in the aggregate productivity statistics and that the current macroeconomic productivity revival may in part reflect the contributions of intangible capital accumulated in the past.

he list. They have no principal objections against offering r elevant parts of it to the GPs. The NMD, however , who is r esponsible for the dr ug item list, has not yet decided what to do. NMD is not r epresented in the pr oject and will pr obably not offer the list fr ee of charge. The pharmacies ar e not willing to let the GPs have access to the dr ug item list as it is at the pr esent, because the list also contains information which the pharmacies want to keep for themselves (for instance about pr ofit margins on pharmaceutical pr oducts). The list thus has to be tailor ed to the needs of the GPs. The dr ug item list is updated every month, each time the version used by GPs has to be pr oduced. The vendors of the GPs' medical r ecord system need to be adapted to make use of the list. The lists can be distributed to GPs dir ectly from NMD or through the vendors of the GPs' systems. The GPs also have available a paper based catalogue, called the Common Catalogue, containing informat

This paper represents a step toward a theory of knowledge reusability, with emphasis on knowledge ma nagement systems and repositories, often called organizational memory systems. Synthesis of evidence from a wide variety of sources suggests four distinct types of knowledge reuse situations according to the knowledge reuser and the purpose of knowledge reuse. The types involve shared work producers, who produce knowledge they later reuse, shared work practitioners, who reuse each other’s knowledge contributions, expertise-seeking novices, and secondary knowledge miners. Each type of knowledge reuser has different requirements for knowledge repositories. Owing to how repositories are created, reusers ’ requirements often remain unmet. Repositories often require considerable rework to be useful for new reusers, but knowledge producers rarely have the resources and incentives to do a good job of repurposing knowledge. Solutions include careful use of incentives and human and technical intermediaries.

This article discusses some key ideas from social informatics research and ends with a brief discussion of the character of the field today. Readers who wish to understand social informatics by learning about its origins and influences may wish to start in that later section and then return to the beginning for a more substantive focus. This article serves as a brief introduction to social informatics for information technology professionals and researchers, and includes numerous references to help interested readers readily locate more comprehensive resources

This paper examines the theoretical and practical problems that arise from attempts to develop formal characterisations and explanations of many work activities; in particular, collaborative activities. We argue that even seemingly discrete individual activities occur in, and frequently draw upon a complex network of factors: individual, social and organisational. Similarly, organisational and social constraints and practices impact upon individual, cognitive processes and the realisation of these in specific tasks. Any adequate characterisation of work activities therefore requires the analysis and synthesis of information from these, traditionally separate sources. We argue that existing frameworks, emanating separately from the respective disciplines (cognitive, social and organisational) do not present an adequate means of studying the dynamics of collaborative activity in situ. An alternative framework, advocated in this paper, is distributed cognition. Its theoretical basis is outlined together with examples of applied studies of computer-mediated work activities in different organisational settings. 1.

Abstract: Corporate mergers, global markets, reduced willingness to relocate, and the increased need to reorganize and respond dynamically – we are entering an era of distributed organizations and groups. New technologies are needed that enable distributed teams to work as though virtually collocated. This case study examines how one such technology, desktop conferencing with application sharing, is used routinely by four groups within a major company. We discuss differing and evolving patterns of use. A range of difficulties arising from impoverished communication are documented. Success factors are identified, focusing on the use of technology facilitation and meeting facilitation. We conclude by describing benefits possible with this merger of communication and application sharing, as well as the challenges of organizational change that may be needed to achieve the benefits.

This paper reports fieldwork from an organization in the print industry, examining a workflow system introduced to the shopfloor. We detail the indigenous methods by which members order their work, contrast this with the order provided by the system, and describe how members have attempted to accommodate the two. Although it disrupted shopfloor work, the system's use was a contractural requirement on the organization to make its services accountable. This suggests workflow systems can often be seen as technologies for organizational ordering and accountability. We conclude that CSCW requirements should acknowledge such exigencies and the organizational status of workflow technologies. Introduction: Workflow Systems and Work Practice This paper reports a field study of workflow technology in a nationally distributed organization in the print industry. By 'workflow technology ' we understand any technology designed to (in some way) give order to or record the unfolding of work activity over time by, for example, providing tools and information to users at
