    Conventions and Commitments in Distributed CSCW Groups
    (Computer Supported Cooperative Work (CSCW): Vol. 11, 37500) Mark, Gloria
    Conventions are necessary to establish in any recurrentcooperative arrangement. In electronic work, they are importantso as to regulate the use of shared objects. Based on empiricalresults from a long-term study of a group cooperating inelectronic work, I present examples showing that the group failedto develop normative convention behavior. These difficulties informing conventions can be attributed to a long list of factors:the lack of clear precedents, different perspectives among groupmembers, a flexible cooperation media, limited communication, thedesign process, and discontinuous cooperation. Further, I arguethat commitments to the conventions were difficult, due to theconventions not reaching an acceptance threshold, uneven payoffs,and weak social influences. The empirical results call for aspecific set of awareness information requirements to promoteactive learning about the group activity in order to support thearticulation of conventions. The requirements focus on the roleof feedback as a powerful mechanism for shaping and learningabout group behavior.

    A Descriptive Framework of Workspace Awareness for Real-Time Groupware
    (Computer Supported Cooperative Work (CSCW): Vol. 11, 37500) Gutwin, Carl; Greenberg, Saul
    Supporting awareness of others is an idea that holds promise forimproving the usability of real-time distributed groupware.However, there is little principled information available aboutawareness that can be used by groupware designers. In thisarticle, we develop a descriptive theory of awareness for thepurpose of aiding groupware design, focusing on one kind of groupawareness called workspace awareness . We focus on how smallgroups perform generation and execution tasks in medium-sizedshared workspaces – tasks where group members frequently shiftbetween individual and shared activities during the work session.We have built a three-part framework that examines the concept ofworkspace awareness and that helps designers understand theconcept for purposes of designing awareness support in groupware.The framework sets out elements of knowledge that make upworkspace awareness, perceptual mechanisms used to maintainawareness, and the ways that people use workspace awareness incollaboration. The framework also organizes previous research onawareness and extends it to provide designers with a vocabularyand a set of ground rules for analysing work situations, forcomparing awareness devices, and for explaining evaluationresults. The basic structure of the theory can be used todescribe other kinds of awareness that are important to theusability of groupware.

    Supporting Public Availability and Accessibility with Elvin: Experiences and Reflections
    (Computer Supported Cooperative Work (CSCW): Vol. 11, 2002) Fitzpatrick, Geraldine; Kaplan, Simon; Mansfield, Tim; Arnold, David; Segall, Bill
    We provide a retrospective account of how a generic event notification service called Elvin and a suite of simple client applications: CoffeeBiff, Tickertape and Tickerchat, came to be used within our organisation to support awareness and interaction. After overviewing Elvin and its clients, we outline various experiences from data collated across two studies where Elvin and its clients have been used to augment the workaday world to support interaction, to make digital actions visible, to make physical actions available beyond the location of action, and to support content and socially based information filtering. We suggest there are both functional and technical reasons for why Elvin works for enabling awareness and interaction. Functionally, it provides a way to produce, gather and redistribute information from everyday activities (via Elvin) and to give that information a perceptible form (via the various clients) that can be publicly available and accessible as a resource for awareness. The integration of lightweight chat facilities with these information sources enables awareness to easily flow into interaction, starting to re-connect bodies to actions, and starting to approximate the easy flow of interaction that happens when we are co-located. Technically, the conceptual simplicity of the Elvin notification, the wide availability of its APIs, and the generic functionality of its clients, especially Tickertape, have made the use of the service appealing to developers and users for a wide range of uses.

    Configuring Awareness
    (Computer Supported Cooperative Work (CSCW): Vol. 11, 2002) Heath, Christian; Svensson, Marcus Sanchez; Hindmarsh, Jon; Luff, Paul; vom Lehn, Dirk
    The concept of awareness has become ofincreasing importance to both social andtechnical research in CSCW. The concept remainshowever relatively unexplored, and we stillhave little understanding of the ways in whichpeople produce and sustain `awareness' in andthrough social interaction with others. In thispaper, we focus on a particular aspect ofawareness, the ways in which participantsdesign activities to have others unobtrusivelynotice and discover, actions and events, whichmight otherwise pass unnoticed. We consider forexample how participants render visibleselective aspects of their activities, how theyencourage others to notice features of thelocal milieu, and how they encourage others tobecome sensitive to particular events. We drawexamples from different workplaces, primarilycentres of coordination; organisationalenvironments which rest upon the participants'abilities to delicately interweave a complexarray of highly contingent, yet interdependentactivities.

    Provocative Awareness
    (Computer Supported Cooperative Work (CSCW): Vol. 11, 2002) Gaver, Bill
    Recently a number of systems have been designedthat connect remote lovers, or strangers in anurban setting. The forms these systems take andthe functions they serve may be unfamiliar, butthey can be seen as extensions of awarenesstechnologies to new domains. Awarenesstechnologies have often been specialised togive information for particular work activitiesor relationships. Given that relationships inthe home or in local communities tend to bedifferent from those of the workplace, it isappropriate that both the form and content ofinformation conveyed to increase awarenessshould be different as well. The systemsdescribed here, for instance, explore newsensory and interaction possibilities, useambiguity to increase engagement, and address awider range of emotional relationships than domost workplace awareness systems. They pointto ways of extending notions of peripheralawareness to new domains on the one hand, andpossibilities for new forms of workplaceawareness on the other.

    Articulating User Needs in Collaborative Design: Towards an Activity-Theoretical Approach
    (Computer Supported Cooperative Work (CSCW): Vol. 11, 37316) Miettinen, Reijo; Hasu, Mervi
    This paper analyses the collaborative design ofa high-technology product, a neuromagnetometerused in the analysis of the activity of thehuman cortex. The producer, Neuromag Company istrying to transform the device from a basicresearch instrument into a means of clinicalpractice. This transition is analyzed as asimultaneous evolution of the product,producer-user network and user activities. Thenetwork is analyzed as a network of activitysystems. Each activity has a historicallyformed object and a motive of its own, as wellas a system of cultural means and expertise. Weuse these to explain and understand theinterests and points of view of the actors inrelation to the product and the contradictionsof the producer-user network. It is suggestedthat the emerging user needs of collectiveactors must be analyzed at three levels. At thefirst level, the use value of the product, itscapacity of solving the vital problems andchallenges of developing user activities, ischaracterized. The second-level analysisconcerns the creation and development of thenecessary complementary tools and services thatmake the implementation and use of the productpossible. This task presupposes collaborationbetween several communities of the innovationnetwork. The third level is the situatedpractical use of the product. In ourexperience, it is advantageous that researcherscontribute with their data to a dialogue inwhich the user needs are articulated.

    Information Systems Development as an Activity
    (Computer Supported Cooperative Work (CSCW): Vol. 11, 37316) Korpela, Mikko; Mursu, Anja; Soriyan, H.A.
    Information systems development (ISD) is analysed in this paper as asystemic work activity, using Activity Analysis and Development (ActAD)as the theoretical framework. ISD is regarded here as the process bywhich some collective work activity is facilitated by newinformation-technological means through analysis, design, implementation,introduction and sustained support, as well as process management. Itis a temporary, boundary-crossing activity which draws its actors,means, rules, etc. from two sides – typically a software companyand the IS user organization. ISD is analysed as a part of a networkof activities, too, around software development and a computer-supporteduse activity. A theoretical framework and a pragmatic checklist arepresented for studying ISD activities. It is argued that the activity-theoretical framework provides a theoretically foundedbut detailed and practicable procedure for studying ISD as a workactivity in context.

    A View of Software Development Environments Based on Activity Theory
    (Computer Supported Cooperative Work (CSCW): Vol. 11, 2002) Barthelmess, P.; Anderson, K.M.
    We view software development as a collaborative activity that is typically supported by a software development environment. Since these environments can significantly influence the collaborative nature of a software development project, it is important to analyze and evaluate their capabilities with respect to collaboration. In this paper, we present an analysis and evaluation of the collaborative capabilities of software development environments using an activity theory perspective. The discipline of software engineering (SE) emerged to study and develop artifacts to mediate the collective development of large software systems. While many advances have been made in the past three decades of SE's existence, the historical origins of the discipline are present in that techniques and tools to support the collaborative aspects of large-scale software development are still lacking. One factor is a common ``production-oriented'' philosophy that emphasizes the mechanistic and individualistic aspects of software development over the collaborative aspects thereby ignoring the rich set of human-human interactions that are possible over the course of a software development project. We believe that the issues and ideas surrounding activity theory may be useful in improving support for collaboration in software engineering techniques and tools. As such, we make use of the activity theory to analyze and evaluate process-centered software development environments (PCSDEs).

    NetWORKers and their Activity in Intensional Networks
    (Computer Supported Cooperative Work (CSCW): Vol. 11, 37316) Nardi, Bonnie A.; Whittaker, Steve; Schwarz, Heinrich
    Through ethnographic research, we document therise of personal social networks in theworkplace, which we call intensionalnetworks . Paradoxically, we find that the mostfundamental unit of analysis forcomputer-supported cooperative work is not at the group level for many tasks andsettings, but at the individual level aspersonal social networks come to be more andmore important. Collective subjects areincreasingly put together through theassemblage of people found through personalnetworks rather than being constituted as teamscreated through organizational planning andstructuring. Teams are still important butthey are not the centerpiece of labormanagement they once were, nor are they thechief resource for individual workers. We drawattention to the importance of networks as mostCSCW system designs assume a team. We urge thatdesigners take account of networks and theproblems they present to workers.
