Introduction 1.1. Virtual teams A surge of research interest in, and increasingly widespread adoption of distributed work in various Virtual teams are comprised of group members settings indicates a growing popularity of virtual who collaborate from different locations using teams supported by modern communication communication technology. Virtual teams can offer technology. Understanding the promise and the flexibility, responsiveness, and diversity of problems of these sociotechical systems can inform perspectives in ways that differ from traditional contemporary theory in the areas of new technology, groups. Despite these benefits, however, virtual group communication, and social psychology, while teams encounter numerous challenges due to their informing management and shaping applications such dispersion and communication limitations, which can as distributed learning groups and virtual impede their effectiveness, or at least require great organizations. Even though the concept of distributed efforts to accommodate to the virtual environment work is not new [see for review 1, 2], new and virtual partners. perspectives on enduring social dynamics come into view from the vantage point of electronically- 1.1.1.

This may be due to dynamics related to Communication media, and the limitations of the the relational aspects discussed above, or due to CMC used by virtual teams, are also characterized as discretionary participation with asynchronous problematic. Nardi and Whittaker [7], for example, participation, free-riding, difficulty integrating argue that proximity and face-to-face interaction are information, or other information-processing aspects critical for establishing collaborative interpersonal of virtual work [see e.g. 17].

Accommodations may emerge Relational communication pertains to the reciprocal or be applied by which participants adjust to the processes of how group members regard one another alternative environment, and the bases of the and how they express that regard. The dimensions of relational dynamics themselves may change. this regard include their affection, cohesion, and task- versus social orientation, among other themes. 1.1.2.

Due to the real decrements in carrying received particular attention in the virtual teams capacity of the CMC medium, computer-mediated literature. Handy [10] asserted that trust cannot be exchanges require more frequent interactions and/or maintained in virtual teams. According to Jarvenpaa more time in order for users to accrue the task and and Leidner [11], trust is traditionally considered to social information about partners to reach the level of be based on “personal relationships and past or future relational development that FtF partners accomplish memberships in common social networks that define more quickly.

Indeed, Other conceptualizations of trust fit CMC better; trust whereas short-term CMC group members benefit in CMC “refers to an expectancy held by an from seeing pictures of one another in order to hasten individual or a group that the word, promise, or their social attraction, group members who exchange verbal or written statement of another individual or a number of messages over time, with no photos to group can be relied upon” [12, p. 718].

As with other Atwater [19] compared experimental CMC and FtF relational dynamics, trust has been asserted and groups on the members’ degree of liking for one found to diminish with the relative lack of visual and another. They found a significant correlation in CMC vocal cues that text-based CMC implies [e.g. 15, 16]. groups between the frequency of a member’s task- 0-7695-2268-8/05/$20.00 (C) 2005 IEEE 2 Proceedings of the 38th Hawaii International Conference on System Sciences - 2005 related message postings and the degree to which of trust had been sociable, exchanged intensely other members liked the contributor.

Both have groups. Their findings confirm that in online been implicated in the literature [e.g. 22]. Thus, relationships trust is maintained through performance another implication may be to encourage frequent consistency rather than cognitive or affective exchange of social and sociable messages, in addition perceptions alone. to task messages. A research question addresses this In another investigation of trust, Iacono and issue: Weisband [25] argued that “action forms” promote What are the relative effects of socially- and trust in virtual groups. These researchers focused task-related messages on affective and substantive specifically on the exchange of messages initiating outcomes in virtual groups? work processes (asking a specific question or As suggested above, trust is also an important proposing action, implicating a response from variable in virtual groups. Like the effects of time others), and messages responding directly to and and message accrual on group liking, trust develops thereby confirming such initiations, as behaviors that over time in longer-term virtual groups consistent equate to trust. Iacono and Weisband facilitated 14 with social information processing theory [20, 23]. self-selected virtual teams among students at several In other approaches, Jarvenpaa and Leidner [11] universities for three weeks, and coded message distinguished between swift trust and alternative, archives from these groups for initiations and developmental trust that may develop in online responses in several categories (getting together, groups.

Additionally, Jarvenpaa and Leidner [11] argue that online while fun messages were few and not related to trust is not as depersonalized or categorically quality, the majority of fun messages occurred in stereotypical as swift trust. Rather, it may be more high performing teams. Additional analyses revealed behaviorally based, inferred from observations about that high performing teams formed quickly and other members’ electronic communication. These handled several activities at once: “If groups focus researchers facilitated 29 global, virtual student teams exclusively or primarily on work process issues, they comprised of 6 to 8 members over six weeks’ time. push the hard work related to work content to the last Participants completed self-reported measures of trust minute.

Traditionally, 1.2. Virtual team behavior control, and the groups tend to procrastinate the production phase of rules of virtual groups their work until half-way through their temporal existence [33]. Delays such as this which may be Given the theoretical connection between the normal in FtF groups can be much more deleterious frequency of specific behaviors and their positive in CMC as a group’s remaining calendar time may impacts on virtual groups’ relational and instrumental not provide sufficient interaction opportunity processes, then such behaviors, if encouraged or considering the retardation of information flow via mandated, might contribute to these groups’ CMC. This is especially true when using optimization. The question becomes what specific asynchronous CMC, where delays between message behaviors can be identified, and whether and how exchanges further strain temporal resources. Thus, they might be encouraged. According to Piccoli and CMC groups should start early in order to avoid Ives [26, p. 575], “Previous studies seem to implicitly running out of time even more severely than we assume that virtual teams will be self-directed—i.e. would see in procrastinating FtF groups. Iacono and that managerial control mechanisms are not required Weisband’s [25] results also indicate that more in this setting.” Even when virtual groups are successful groups began their work quickly. specifically instructed about useful practices or rules, Rule 2: Communicate frequently. As with the but left to their own decision to adopt them or not, first rule, social information processing theory [5] such groups tend to ignore these rules until direct indicates the importance that ample messaging interventions and social arrangements draw explicit portends for group development. The value of attention to their rule-following failures [27]. communicating frequently is also identified as a However, the managerial manipulation or critical behavior in Iacono and Weisband’s [25] and incentivization of such behaviors may provide a Jarvenpaa and Leidner’s [11] research, where trusting worthwhile experimental and practical approach to behaviors, or trust perceptions, were associated with understanding and improving virtual teams, and the frequent exchanges. Communicating frequently also deliberate management of virtual teams is a topic that allows the dispersion of activity over time, avoiding is receiving growing attention [e.g. 28]. the pile-up of activity toward the end of groups’ work In sociological and psychological literatures, the time periods.

Norms and rules may be particularly substantive work simultaneously. This principle is potent in CMC. According to Lea and Spears [31], also derived from issues about temporal pace in CMC CMC offers little apparent information about and the normal sequencing of events in FtF groups. individual characteristics, making attributions based Traditionally, groups first set about organizing, on the conformity to or deviance from group norms defining, and allocating tasks before members begin more salient and important.

In CMC groups, especially those argued that implicit norms, or “conventions,” are with limited time, this sequence can be counter- more difficult to appropriate and observe in functional for two reasons. First, if approached distributed as opposed to long-term co-located linearly and sequentially, organizing activities may groups, and that explicit conventions invented by consume so much time that there is insufficient groups themselves are violated, her analysis did not opportunity for substantive exchange given the pace examine the deliberate introduction of behavioral of CMC. Secondly, the perception that it is rules as a managed or incentivized system. Based on undesireable to begin working on collaborative tasks the social information processing theory [5] and the before organizing them is fallacious in many cases. In findings reviewed above, a number of coordination tasks where duplication of effort might lead to rules were devised for empirical testing of their multiple perspectives about the same input effects on the relational and instrumental dynamics of information, organizing in order to minimize virtual teams in a system where the rules were duplication is not only unnecessary but explicitly encouraged and in some cases incentivized. disadvantageous.

More importantly, Weisband’s [25] findings on the simultaneous value accomplishing sub-tasks in a timely way reduces the of work process and work content exchanges lend uncertainty that participants may experience in an credence to this rule. interaction environment where there is less likely Rule 4: Overtly acknowledge that you have perceived accountability [34]. Social information read one another’s messages. In asynchronous processing theory [5] recognizes the communication CMC it is difficult to tell whether others have read of vulnerability patterns [35] as a means of one’s postings. Failure to do so may be due to developing trust in CMC. That is, actors must put senders’ errors (e.g. emailing to an individual rather themselves in a position in which another partner can than the group), system errors (e.g. network, server, provide an outcome which will, even if met, not be or software malfunctions), or receiver behavior greater in benefit to the actor than the potential costs (failing to check). Moreover, unless the email to the actor should the partner fail. If a member could software used has an automatic notification option, do the job herself but chooses to wait for a partner to once a receiver has gotten a message, it requires overt do it, there is vulnerability due to the greater costs if acknowledgement in order for the sender to know. In the member must share in the failure or do the work FtF settings message reception may be more herself if the partner reneges. Vulnerability and passively inferred through the attention monitoring validation lead to trust over repetitions. In a sense the that co-presence provides [7]. As discussed above, greatest demonstration of trustworthiness may be the time, channels, and member distribution make it honoring of agreements [12]. difficult for virtual team members to know if they are In order to test the utility of these rules and the experiencing common knowledge, and as Cramton principles on which they are based, the following [3] has detailed it is easy to assume that common general hypothesis was generated: knowledge is operating in distributed groups when in The greater the adherence to each of the rules fact it is not. Explicit acknowledgements should of virtual groups, the more that virtual team members combat this problem. Iacono and Weisband’s [25] trust the group, like each other, and perform better findings on the value of responses to proposals, not work. just the proposals themselves, supports this suggestion. 2. Methods Rule 5: Be explicit about what you are thinking and doing. Social information processing In order to ascertain whether any of these rules theory [5] holds that CMC can translate into verbal had impacts if they were managed, i.e. if variation in behavior that which is traditionally done nonverbally, their adherence could be deliberately manipulated, a and the articulation of feedback messages is one quasi-experimental procedure was employed.

A formula was presented by which course participation, for which continuation in the decrements would be penalized. The final third of courses implied consent.

In contrast, organizing one’s grades on these assignments, and actually messages suggest or discuss procedures related to improved them.
