In this article, we summarize and review the research on teams and groups in organization settings published from January 1990 to April 1996. The article focuses on studies in which the dependent variables are concerned with various dimensions of effectiveness. A heuristic framework illustrating recent trends in the literature depicts team effectiveness as a function of task, group, and organization design factors, environmental factors, internal processes, external processes, and group psychosocial traits. The review discusses four types of teams: work, parallel, project, and management. We review research findings for each type of team organized by the categories in our heuristic framework. The article concludes by comparing the variables studied for the different types of teams, highlighting the progress that has been made, suggesting what still needs to be done, summarizing key leamings from the last six years, and suggesting areas for further research.

Telework has inspired research in disciplines ranging from transportation and urban planning to ethics, law, sociology, and organizational studies. In our review of this literature, we seek answers to three questions: who participates in telework, why they do, and what happens when they do? Who teleworks remains elusive, but research suggests that male professionals and female clerical workers predominate. Notably, work-related factors like managers' willingness are most predictive of which employees will telework. Employees' motivations for tele-working are also unclear, as commonly perceived reasons such as commute reduction and family obligations do not appear instrumental. On the firms' side, managers' reluctance, forged by concerns about cost and control and bolstered by little perceived need, inhibits the creation of telework programmes. As for outcomes, little clear evidence exists that tele-work increases job satisfaction and productivity, as it is often asserted to do. We suggest three steps for future research may provide richer insights: consider group and organizational level impacts to understand who telework affects, reconsider why people telework, and emphasize theory-building and links to existing organizational theories. We conclude with lessons learned from the telework literature that may be relevant to research on new work forms and workplaces.

The bulk of our understanding of teams is based on traditional teams in which all members are collocated and communicate face to face. However, geographically distributed teams, whose members are not collocated and must often communicate via technology, are growing in prevalence. Studies from the field are beginning to suggest that geographically distributed teams operate differently and experience different outcomes than traditional teams. For example, empirical studies suggest that distributed teams experience high levels of conflict. These empirical studies offer rich and valuable descriptions of this conflict, but they do not systematically identify the mechanisms by which conflict is engendered in distributed teams. In this paper, we develop a theory-based explanation of how geographical distribution provokes team-level conflict. We do so by considering the two characteristics that distinguish distributed teams from traditional ones: Namely, we examine how being distant from one's team members and relying on technology to mediate communication and collaborative work impacts team members. Our analysis identifies antecedents to conflict that are unique to distributed teams. We predict that conflict of all types (task, affective, and process) will be detrimental to the performance of distributed teams, a result that is contrary to much research on traditional teams. We also investigate conflict as a dynamic process to determine how teams might mitigate these negative impacts over time. (Distributed Work; Distributed Teams; Virtual Teams; Conflict) In response to a variety of factors that characterize the modern economy-including the global expansion of the marketplace and the businesses that serve it, the rise in mergers and acquisitions, and heightened competitive pressures to reduce the time to develop productsorganizations increasingly are assembling teams whose members are drawn from sites far and near. Geographically distributed teams face a number of unique challenges, including being coached from a distance, coping with the cost and stress of frequent travel, and dealing with repeated delays (Armstrong and Cole 2002). Many scholars and practitioners have noted and expressed concern about one such challenge facing these teams: the prevalence and severity of conflict. Justifying their concern, reports from the field indicate that conflict is disruptive to performance in distributed teams.Field studies further indicate that geographically distributed teams may experience conflict as a result of two factors: The distance that separates team members and their reliance on technology to communicate and work with one another. Distance and technology mediation have gone unexplored in existing models of conflict and performance in teams because their authors, for the most part, assumed that team members were collocated and communicating face to face. As a result, whether these two factors spur new antecedents of conflict is not known, nor is it clear how conflict in distributed teams might be reduced. ...

A lthough organizational scholars have begun to study virtual work, they have yet to fully grapple with its diversity. We draw on semiotics to distinguish among three types of virtual work (virtual teams, remote control, and simulations) based on what it is that a technology makes virtual and whether work is done with or on, through, or within representations. Of the three types, simulations have been least studied, yet they have the greatest potential to change work's historically tight coupling to physical objects. Through a case study of an automobile manufacturer, we show how digital simulation technologies prompted a shift from symbolic to iconic representation of vehicle performance. The increasing verisimilitude of iconic simulation models altered workers' dependence on each other and on physical objects, leading management to confound operating within representations with operating with or on representations. With this mistaken understanding, and lured by the virtual, managers organized simulation work in virtual teams, thereby distancing workers from the physical referents of their models and making it difficult to empirically validate models. From this case study, we draw implications for the study of virtual work by examining how changes to work organization vary by type of virtual work.

In this paper, we broaden the concept of interdependence beyond its focus on task to include technology, defining technology interdependence as technologies' interaction with and dependence on one another in the course of carrying out work. With technologies increasingly aiding knowledge work, understanding technology interdependence may be as important as understanding task interdependence for theories of organizing, but the literature has yet to develop ways of thinking about technology interdependence or its impact on the social dynamics of work. We define a technology gap as the space in a workflow between two technologies wherein the output of the first technology is meant to be the input to the second one. Using data from an inductive study of two engineering occupations (hardware engineering and structural engineering), we analyzed engineers' gap encounters (episodes in which a technology gap appeared in the course of action) and found striking differences in how engineers minded the gaps. Hardware engineers minded the gaps by coordinating technologies via “bridges” that automated data transfers between technologies. Structural engineers, in contrast, allowed technology gaps to persist even though traversing gaps consumed significant time and effort. Our findings highlight a difference between task and technology in the degree of coordination necessary for success. Managers in our study designed policies around technology interdependence and coordination not to manage technology most efficiently, but to manage work and workers in a manner consistent with occupational structures and industry constraints. We discuss the implications of our findings for theories of organizing work.
