Coordination Structures and System Restrictiveness in Distributed Group Support Systems

Most GSS research has studied the impact of restricting group interaction to GSS-prescribed coordination structures with face-to-face groups, while Distributed GSS (DGSS) has been largely ignored. Due to the nature of mediated communication in asynchronous interaction, it is relatively difficult to coordinate distributed groups, and a special coordination structure must be arranged to overcome these difficulties. This study examines the effect of system restrictiveness of coordination structures in an asynchronous environment. A 2 × 2 factorial experiment was designed with two independent variables – sequential vs. parallel coordination mode, and with vs. without a leader – to construct coordination structures with varying degrees of restrictiveness. The study finds that less restrictive coordination structures are more appropriate to support asynchronously interacting distributed groups. Objective decision quality is equal for both parallel and sequential coordination mode, but is significantly better with a group leader. Groups with parallel coordination mode have a stronger belief that the decisions they made are of higher quality than those of groups with sequential coordination mode. In groups with a leader, communication effectiveness is better. Satisfaction with a decision process is higher in parallel coordination groups and in groups with a leader. There is also a significant interaction effect. Satisfaction with the decision process is higher in sequential coordination groups with a leader than sequential coordination groups without a leader.     

Electronic Meetings and Intense Group Conflict: Effects of a Policy-Modeling Performance Support System and an Audio Communication Support System on Satisfaction and Agreement

Ad-hoc decision teams were used to examine the effects of an electronic meeting system (EMS) on group satisfaction and agreement. The decision task provoked intense conflict of values. The EMS had two core features - a policy-modeling group performance support system (incorporating structured decision methods and computer-supported cognitive feedback using Multi-Attribute Utility Analysis and Social Judgment Analysis), and an audio-based group communication support system (allowed dispersed members to communicate by voice). Policy groups reached higher agreement than conventional decision-making groups, apparently due primarily to the structure for cognitive-conflict tasks that was imposed on group discussion rather than computer-supported cognitive feedback displays. Audio groups were more satisfied with the conflict process than face-to-face groups. Decision agreement was equivalent across the two media. These audio effects for a highly equivocal task represent a further challenge to media richness theory.     

Individual Priming in Virtual Team Decision-Making

Virtual teams have different interactions than face-to-face teams because they rely on information and communication technologies, which can impede or assist certain human cognitive processes. Past research has shown that although virtual teams exchange more information than face-to-face teams, poor decisions often result, because team members do not consider the unique information they receive from others. Drawing from cognitive psychology, our research explored a unique way to improve team decision-making through the use of cognitive priming. We proposed that priming group members to pay attention to others or to engage in counterfactual thinking would improve team members’ cognition and, therefore, team performance. Prior research with individuals and brainstorming teams has shown these forms of priming to improve performance; however, no research has attempted to use priming to improve the outcomes of virtual team decision-making, which requires deeper interaction and cognitive involvement than brainstorming. We performed two lab experiments using primes that have been found to improve the individual decision-making process. We found that priming had some impact, but it did not significantly improve decision quality. Various reasons are discussed to explain why priming techniques may not be as powerful in teams as in individuals, and future research ideas are suggested to build on our initial work on priming in virtual team decision-making.     

Meeting Scheduling: Face-to-Face,Automatic Scheduler,and Email Based Coordination

We conducted laboratory experiments based on small groups (4 to 5 participants) to compare the performance of 4 different mechanisms of meeting scheduling: (a) face-to-face coordination wherein individuals negotiate in person and arrive at a consensus on the timing of the meeting, (b) email as the sole communication medium with no structured support, (c) the calendar-based scheduling mechanism using email, and (d) an automated scheduler. Participants of the experiment were drawn from a university in Hong Kong. The experiment was implemented based on the real task of meeting scheduling among project groups that had to meet several times during a 3-month period to work on their project (regardless of this experiment). Postexperimental surveys were used to assess satisfaction with agreed meeting time and perceived efficiency in coordination. The frequency of scheduling conflicts also was measured. Data analysis indicates that even with higher scheduling conflicts among the group members, participants in general showed more satisfaction with the meeting time reached during the face-to-face meeting and also concurred on the efficiency of face-to-face coordination. Overall, they preferred communication-oriented approaches such as face-to-face coordination over decision-oriented ones such as the automated scheduler. We discuss the result of data analysis from the perspective of cultural implications on meeting scheduling and on virtual process management.     

The Effects of Media and Task on User Performance: A Test of the Task-Media Fit Hypothesis

This research was designed to examine the task-media fit hypothesis, an extension to media richness theory that predicts the objective performance of various media for a number of task types. To examine this model, dyads communicating through face-to-face, videophone, telephone (i.e., audio-only communication), or synchronous computer-mediated communication worked in a laboratory experiment to address an intellective or negotiation task. The intellective task required that each dyad member effectively share factual information that each individual independently held. The negotiation task required that each dyad member effectively share preferences based on personal values and reach an agreement. The results of the study provide mixed support for the task-media fit hypothesis. In general, the results for the negotiation task largely supported the theory while the results for the intellective task did not support the theory. These results help to clarify limitations and provide extensions to the theory by demonstrating how variations in task processes and communication media act to mediate task performance. The implications of these results for future research and practice are discussed.     

The Interactive Effect of Authentic Leadership and Leader Competency on Followers’ Job Performance: The Mediating Role of Work Engagement

The effect of authentic leadership and leader competency on employee job performance has received growing attention in the past decades; however, few studies have simultaneously integrated these two leadership perspectives. We have thus developed a mediated moderation model to test the interactive effect of authentic leadership and competency on followers’ job performance through work engagement. Based on a sample of 248 subordinate–supervisor pairs, hierarchical regression analyses reveal that (1) authentic leadership positively relates to followers’ task performance and organizational citizenship behavior (OCB); (2) leader competency moderates the relationship between authentic leadership and OCB; (3) and followers’ work engagement mediates the main effect of authentic leadership and the interactive effect of authentic leadership and competency on followers’ task performance and OCB. All the three results are consistent with our hypotheses.     

Group Consensus: The Impact of Multiple Dialogues

The research results on group consensus have been ambiguous within the field of Group Support Systems (GSSs). Some research studies have shown that groups using multiple communication channels produce more ideas, and more unique ideas than groups using a single communication channel. In addition, a second set of research findings have shown that groups using GSSs report group members hold less consensus with the group's decision. This research studies more closely how these two characteristics; communication channel and consensus, interact. Specifically, can less consensus be a function of the choice of channels used in problem solving. The results show that groups using a single communication channel generate more actual consensus than groups using multiple communication channels. Furthermore, the single channel discussions provide more integrative comments and these integrative comments may help explain the difference in consensus. These results suggest that those striving for consensus from group members should consider production methods used to create the information that is to be used in the decision.     

The Effects of Integrating Cognitive Feedback and Multi-attribute Utility-Based Multicriteria Decision-Making Methods in GDSS

Cognitive conflicts arise within groups because the members of a group view a problem from different perspectives, even when they have similar interests in achieving a goal. Disagreement within a group may occur due to: (a) differing judgment policies among the members, (b) inconsistency by any member in using a judgment policy, (c) group process losses that prevent group members from understanding each other better, or (d) limited processing capability which may prevent group members from processing all information effectively. Disagreement is especially likely when policies, processes, or information are conflicting in nature.A level 2 GDSS to aid judging in cognitive conflict tasks is presented that combines cognitive feedback and Multi-attribute utility (MAU) theory based multicriteria decision-making techniques with the communication structure and activity-structuring capabilities of a level 1 GDSS. Though cognitive feedback and MAU methods have been used separately to help groups resolve cognitive conflicts, never before have the two decision aids been used together in a computer-based collaborative system.The contributory effects of the components of this GDSS design were empirically tested in a laboratory setting. Three treatments: an unaided face-to-face meeting, a level 1 GDSS supported meeting, and a level 2 GDSS supported meeting were compared in a repeated measures experimental design.Results largely supported the proposed research hypotheses. Some specific findings include: (1) the level 2 GDSS reduced disagreement between group members and improved consistency of judgments better than the other meeting environments did; (2) there was no significant difference in the reduction of disagreement between the level 1 GDSS and face-to-face meetings; and (3) while there was no difference in improvement of consistency of individual judgments between the face-to-face and level 1 GDSS supported meetings, group judgments made in face-to-face meetings were more consistent.     

Remote Leadership,Communication Effectiveness and Leader Performance

As remote work arrangements have gained in popularity, workforce dispersion has become increasingly widespread. Little research to date has examined how physical distance influences leader–follower communication effectiveness or leader performance. Building on top of transformational leadership theory, this paper explores how perceived leader performance is influenced by leadership style, physical distance, and communication effectiveness between leaders and followers. A survey of 138 followers, reporting to a total of 41 leaders, was conducted and data were analyzed at the individual follower-level using the Partial Least Squares (PLS) technique. Our model explained 45% of the variance in communication effectiveness and 67% of the variance in perceived leader performance. Consistent with past empirical findings, transformational leadership was associated more strongly with perceived leader performance than transactional contingent reward leadership. Communication effectiveness was also a strong predictor of leader performance, and furthermore acted as a mediator of leadership behavior on performance. Surprisingly, distance had no influence on either communication effectiveness or perceived leader performance. Implications for theory and practice are discussed.     

Exploring Individual Trust Factors in Computer Mediated Group Collaboration: A Case Study Approach

Trust has become more and more important in the context of mixed use of longitudinal face-to-face and computer mediated group collaboration using Group Support System tools. Previous research has investigated trust factors in different dimensions. This paper takes the perspective of individual trust and aims to explore the new trust factors and also their detailed second level trust sub-factors in computer mediated collaboration over time. We have taken the interviews using the student groups during the two year-long collaboration project based case studies. We have validated the previous factors and found seven new trust factors and thirty one sub-factors which are associated with the main factors. Furthermore, based on the new factors, this paper has also designed an innovative trust traffic light model with suggested steps which could be easily used to help analyze the trust factors development over time for future longitudinal studies.     

Using and Influence Level of Information to Explain the Non-consensus Process Loss

Much of the Group Support System (GSS) literature comparing GSS groups with manual groups has produced contrarian results. One of the more confusing is that GSS groups have a higher level of non-consensus than manual groups. Lack of consensus in GSS groups is considered to be a negative aspect of GSS. This paper argues that low levels of consensus are not necessarily harmful and should be expected given the assumptions about GSSs. This study uses an alternate measure to compare face-to-face groups with GSS groups; an influence level of information. Experimental results using an influence level of information show no difference between face-to-face group members and GSS group members. We discuss these implications, as well as additional directions for further consensus research.     

Asynchronous Computer-mediated Communication versus Face-to-face Collaboration: Results on Student Learning, Quality and Satisfaction

Although there has been more than a decade of literature on computer-mediated communication in education, the research has been unclear as to whether it is an effective replacement for face-to-face (FtF) collaboration. This study sought to add to this body of research by exploring the effects of two modes of collaboration on student groups. Following a repeated-measures experimental design, each student group collaborated on two case studies, one using face-to-face collaboration and the other using asynchronous computer conferencing technology as a means of collaboration. Empirical findings indicate that asynchronous collaboration is as effective as face-to-face collaboration in terms of learning, quality of solution, solution content, and satisfaction with the solution quality. However, students were significantly less satisfied with the asynchronous learning experience, both in terms of the group interaction process and the quality of group discussions.     

Strengthening Identification with the Team in Virtual Teams: The Leaders' Perspective

The number of virtual teams is increasing in today's workplaces. In virtual teams, the members can have different cultural backgrounds, they often work in different countries and are professionals in their own fields. In addition, as such diverse and dispersed teams communicate mainly through communication technology this raises the challenge for the team leader of how to unify the team and get the members to identify themselves with the team. This qualitative study focuses on four virtual team leaders and their attempts to strengthen the team members' identification with the team through computer-mediated communication. The results show four different tactics employed in enhancing identification with the team: catering for the individual, giving positive feedback, bringing out common goals and workings and talking up the team activities and face-to-face meetings. The roles of organizational change and technology in identification with virtual teams are also discussed.     

Distributed group support systems: Social dynamics and design dilemmas

A “distributed group support system”; includes decision support tools and structures embedded within a computer‐mediated communication system rather than installed in a “decision room.”; It should support groups who are distributed in space but not time ("synchronous”; groups), as well as “asynchronous”; groups whose members participate at different times. Pilot studies conducted in preparation for a series of controlled experiments are reviewed in order to identify some of the problems of implementing such a system. Many of the means used by groups meeting in the same place at the same time to coordinate their activities are missing. Embedding decision support tools within a different communications medium and environment changes the way they “work.”; Speculations are presented about software tools and structuring or facilitation procedures that might replace the “missing”; coordination channels.     

The impact of individualism on buyer–supplier relationship norms,trust and market performance: An analysis of data from Brazil and the U.S.A.

This study focuses on the impact of the cultural dimension of individualism, face-to-face communication and the effect of relational norms such as supplier involvement and trust on the market performance of buyer firms. We use the culture literature and social exchange theory to test hypotheses using a sample of Brazilian and US manufacturing firms. The data were analyzed using variance-based structural equation modeling, employing nonlinear partial least squares regression. Our findings indicate that individualism is negatively related to the involvement of suppliers in the production process but is not associated with trust in suppliers. In addition face-to-face communication seems to have a positive effect on supplier involvement and trust.     

CONFIDE: A Collective Decision-Making Procedure Using Confidence Estimates of Individual Judgements

An algorithm (termed CONFIDE) is proposed that may capture many of the benefits of group decision making without the necessity of face-to-face interaction. The algorithm allows individual decision makers to differentially weight the contributions from members according to the confidence with which each member holds to their opinions. The CONFIDE algorithm is compared to both face-to-face group decisions and simple averaging of group members opinions on the Lost-at-Sea ranking task. Results indicate that, in terms of decision quality, the CONFIDE algorithm produces solutions equal to that of the face-to-face group decision method and significantly better than the solution achieved by simple averaging of group members responses.     

The Voice Link: A Moderated Mediation Model of How Ethical Leadership Affects Individual Task Performance

This study empirically examines the proposition that ethical leadership may affect individuals’ task performance through enhancing employees’ promotive voice. Our theoretical model was tested using data collected from employees and supervisors in a high-tech company located in South China. Analyses of multisource three-wave data from 37 team supervisors and 176 employees showed that ethical leadership could significantly affect individuals’ task performance through promotive voice. Further, it was found that the relationship between ethical leadership and promotive voice was moderated by leader–leader exchange. Specifically, ethical leadership may significantly enhance employees’ promotive voice when leader–leader exchange is low. The theoretical and practical implications of these findings are discussed.     

Performance in Product versus Service Supplier Relationships

ABSTRACT

Today's rapidly changing and competitive marketplace has forced channel members to devote increased attention and resources to providing consumers with a seamless delivery of products and services. This seamless delivery occurs through social integrative relationships between channel members, supported by the application of information technology. Achieving integration is a difficult task that may vary based on whether a product or a service is involved. This paper proposes that manufacturer integrative relationships with product suppliers may develop with lower levels of seamless delivery when compared to manufacturer integrative relationships with service suppliers. Further, the paper discusses how the application of information technology may impact manufacturer-supplier relationships and performance.     

Creating and sustaining trust in virtual teams

Conventional wisdom assumes that trust develops from a history of interpersonal interactions and communication, through which people come to ‘know and trust’ one another. In virtual teams, however, establishing trust can be complicated: members may have no past on which to build, no future to reference, and may never even actually meet face-to-face. Swift but fragile trust can develop early in a team's life cycle. Yet, if swift trust doesn't develop or even dissipates, members need to find ways of building trust in each other. To this end, an understanding of how trust impacts a virtual team's development will help managers and team leaders to facilitate and improve team success. Herein, we describe the three components of trust (ability, integrity, and benevolence) and identify which of these are critical to each life cycle stage (establishing the team, inception, organizing, transition, and accomplishing the task) of the virtual team. Proposed action steps for each stage show managers and team leaders how to help members develop trust and sustain it through the project's successful completion.
