Channel and Recipient Characteristics: Effects on Communication Effectiveness and Performance

One significant problem that organizations face today is their ability to disseminate information within and across their organizational boundaries efficiently. The purpose of this dissertation is to examine how communication media with different characteristics, and individual recipients with different characteristics, influence the performance of the message recipients on tasks that are dependent on the message. Well known communication media theories (e.g., Daft & Lengel, 1986) have come under scrutiny for weak empirical support and newer theories have emerged (e.g., Dennis, Fuller, & Valacich, in press) that will require empirical testing to validate. This dissertation represents an initial empirical test of several elements of Media Synchronicity Theory (MST). This dissertation is composed of three essays which describe a series of empirical studies. The studies were carried out (1) to create measurement scales to psychometrically assess individuals perceptions of media characteristics/capabilities; (2) to experimentally manipulate two media capabilities and evaluate downstream, individual performance relative to a communicated message; and (3) to assess recipient retention of communicated information after a time delay from the experimental manipulations of media capabilities. The ultimate goal of this research is to provide a rigorous, tightly controlled evaluation of several aspects of MST, and to propose and test two media appropriation factors as an extension to MST. This dissertation is organized in the following manner. The first chapter provides an introduction to the three essays. This introductory chapter will provide a brief theoretical discussion of MST, how MST has evolved over the last decade, and brief introductions to each essay. The second chapter includes the first essay, which will describe the instrument development studies. The third chapter includes the second essay, which will describe the first experimental study. The fourth chapter, containing the third essay, will describe the follow-up experimental study that incorporates a longitudinal aspect into the research model. Finally, the fifth chapter is composed of a summary section that will briefly discuss the dissertation as a whole

Computer-Mediated Communication and Innovation: Do Communication Media Properties Influence Innovative Thinking Processes?

This paper concerns potential impacts that characteristics of communication media in computer-mediated problem solving in groups have on group-members’ innovative thinking. Different processes involved in effective idea generation and problem solving are presented, and we discuss how three characteristics of communication media relevant for group collaboration aiming at producing innovative ideas might influence the group process. A research model is presented, and hypotheses regarding the effects of affordances on innovative thinking are put forth. We finally describe a possible methodological approach that might be applied in order to test the proposed hypotheses

Reciprocal Effect of Team Commitment and Media Richness in eCollaboration: A Conceptual Model

One of the major areas of E-Business applications is the sourcing of expert human resources globally with the help of virtual teams operating in various parts of the world. Major corporations are increasingly using e-Collaboration technologies to make the functioning of these teams economical and effective. The tasks performed by these teams can vary from software design and development to providing back office services like call center support, technical support, transcription services etc. Additionally, after 9/11 corporations have embarked on major initiatives to implement e-Collaboration technologies at the global level to help reduce travel. Extensive work has been done to study the decision-making performance of face-to-face and virtual teams. However, previous studies have found conflicting results regarding the impact of media richness on decision-making performances of teams. This paper posits the significant role of media type on the communication richness when team members have low commitment to the collaborative team projects. A conceptual model that depicts the influence of media type on satisfaction, team conflict, social influence, and supportiveness that influences the team commitment has been developed. The influence of team commitment on communication richness is also examined. A controlled lab experiment is designed to test the research model

The effect of normative social influence and cultural diversity on group interactions

Motivated by concerns regarding the impact of cultural diversity on group interaction processes and a desire to extend the Social Influence Model of Technology Use, this paper discusses the impact of normative social influence on enhancing group media use and group decision making performance over time in different cultural group compositions. This paper proposes that the strength of attraction to the group influences the similarity in media perception and use of group members. The similarity of group media perception and use is proposed to influence group performance. Concurrently, group cohesion, similarity of media perception and use, and group performance are positively correlated over time. Since culture affects individuals' values, beliefs and behavior, this paper proposes that the degree of similarity in media perception and media use may differ when group composition varies by culture. Several propositions for empirical examination are highlighted. Finally, the paper concludes with a discussion of the importance and implications of understanding cultural diversity and social influence on technology use and group performance. © 2006 IEEE

Messaging Media Perceptions and Preferences: An Exploratory Study

Although a significant amount of research has focused on traditional media choice and use and even on some of the “new” media, these studies have neglected Instant Messaging (IM) and Short Messaging Service (SMS). This study offers a novel exploration of students’ perceptions of and preferences for two new messaging media (IM and SMS) in the context of the use of other traditional and new communication media (face-to-face, telephone, and email) in their university learning activities. The findings reveal media richness is rated in decreasing order of face-to-face, telephone, IM, email and SMS. Face-to-face is the most preferred medium in most communication activities. Students preferred email in a manner similar to the telephone. This study has identified the importance of media experience, familiarity and frequency of use, when selecting media. The overall findings of this study support media richness theory

Idea Generation in Technology-Supported Teams: A Multilevel Motivational Perspective

In this research, we draw on multilevel theory to understand the interplay between team characteristics—team size and team dispersion—and individual goal striving in influencing individual idea generation performance. We conducted a laboratory study involving 185 individuals nested in 34 brainstorming teams and found that individual goal striving is a stronger predictor of individual idea generation performance in dispersed team contexts compared to co-located team contexts and in larger teams than in smaller teams. The implications of the findings for theory and practice are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/116288/1/Srinivasan et al. 2012.pd

Latent Growth Modeling and Latent Class Analysis

Geared towards capturing change, longitudinal research is able to provide insight into a variety of phenomena of interest to IS researchers, especially IT adoption and use. However, its potential is constrained by the data analysis methods typically used. In this paper, I introduce an advanced technique – Latent Curve Modeling – and demonstrate how this technique supports longitudinal data analysis using system use data collected at an international management consulting firm. Latent Curve Modeling helps capture temporal patterns better than existing methods, and provides methods to identify the causes of change in patterns. With rich information in the discussion of the technique and the results of the empirical tests, I recommend it as a valuable option for IS researchers who are interested in research involving temporal changes
