Media Production: Towards Creative Collaboration Using Communication Networks

To examine the diffusion of remote collaboration technologies within the media production industries, a series of case studies was recently conducted with early adopters of advanced electronic networks in Sydney, Los Angeles and London. The studies assessed: 1) user reactions to these collaboration technologies and types of activities being supported and 2) factors influencing their adoption decisions. Interviews conducted also provided early indications of the conditions likely to facilitate remote collaboration and the likely impacts on work practices in media production organizations. It was established that electronic delivery, remote access to resources and materials, and remote creative collaboration were all being carried out, even internationally. Although most network applications were routine substitutions for non-electronic equivalents (e.g. couriers or catalogue browsing), some did involve shared creative activities, thus confirming that remote creative collaboration is a viable option. Key factors influencing network adoption were cost considerations and regulatory issues, time savings and productivity, and security concerns. Certain industry segments -- animation, post-production, and advertising -- were more likely to be early adopters, as were companies who found innovative ways to achieve greater benefits. Conditions likely to facilitate remote collaboration include more sophisticated change-agent strategies, increasing the perceived control of creative outputs, developing and maintaining trust, providing more auxiliary support for coordination needs, and making more effective use of timing and time-zone differences. Likely impacts of remote collaboration in media production are: more overlap between pre-production, production, and post-production activities; faster work pace; enhanced creativity; and improved quality of work life.     

Virtual Teams and the Appropriation of Communication Technology: Exploring the Concept of Media Stickiness

This paper reports on an exploratory study ofthe evolving use of communication tools by sixglobally distributed teams. The analysissuggest that although teams have similarstart-up conditions they evolve in differentways. We describe these differences as being aresult of the different routine patterns ofmedia use that the team members mutuallyenacted. Based on an analysis of six US-Dutchvirtual teams, we propose the notion of `mediastickiness', a phenomenon the teamsexperienced during the process of structuringmedia-use patterns. We will argue that in thecase of virtual teams, the evolution of mediausage seems to be path dependent. Steps takenby a team in the early stages of its life cycleconstrain later flexibility in terms of mediausage. Media stickiness has severalimplications both for the way to manage virtualteams as well as for the way teams deal withinformation problems that seem to be endemicfor global virtual teams.     

Supporting Scientific Collaboration: Methods, Tools and Concepts

This paper discusses the interrelationship between e-Science and CSCW in terms of key substantive, methodological and conceptual innovations made in both fields. In so doing, we hope to draw out the existing relationship between CSCW and e-Science research, and to map out some key future challenges where the two areas of research may become more closely aligned. In considering what may be required to draw the two more closely together, the paper focuses primarily on investigations that have been undertaken in two dedicated initiatives into e-Science, along with the key issues emerging from these studies.     

Mining Task-Based Social Networks to Explore Collaboration in Software Teams

Mining social networks from software repositories is becoming a popular research area. Mining approaches often use technical artifacts, such as source code, or communication artifacts, such as emails, to create social networks. The authors describe a repository-independent approach of mining task-based communication in social networks. In their approach, collaborative tasks that tools record in software engineering repositories provide the constructed networks' context that link developers' task-based social networks if they've communicated about a collaborative task. These social networks demonstrate the applicability of their approach through two research studies that mined the IBM Rational Jazz development repository. They then propose practical applications that utilize their approach to directly support development projects.

Roles of Orientation in Tabletop Collaboration: Comprehension, Coordination and Communication

In order to support co-located collaboration, many researchers are now investigating how to effectively augment tabletops with electronic displays. As far back as 1988, orientation was recognized as a significant human factors issue that must be addressed by electronic tabletop designers. As with traditional tables, when people stand or sit at different positions around a horizontal display they will be viewing the contents from different angles. One common solution to this problem is to have the software reorient objects so that a given individual can view them ‘right way up.’ Yet is this the best approach? If not, how do people actually use orientation on tables? To answer these questions, we conducted an observational study of collaborative activity on a traditional table. Our results show that the strategy of reorienting objects to a person’s view is overly simplistic: while important, it is an incomplete view of how people exploit their ability to reorient objects. Orientation proves critical in how individuals comprehend information, how collaborators coordinate their actions, and how they mediate communication. The coordinating role of orientation is evident in how people establish personal and group spaces and how they signal ownership of objects. In terms of communication, orientation is useful in initiating communicative exchanges and in continuing to speak to individuals about particular objects and work patterns as collaboration progresses. The three roles of orientation have significant implications for the design of tabletop software and the assessment of existing tabletop systems.

Trust,Performance, and the Communication Process in Ad Hoc Decision‐Making Virtual Teams

This research explores the communication process variables that potentially determine trust and performance quality in ad hoc virtual teams to better inform the choice of communication media for virtual groups engaged in decision‐making tasks. Results of a survey indicate that virtual copresence is significantly correlated with intrateam trust and the performance quality that teams achieve. Results also accentuate the prominent role of trust in the virtual collaborative decision‐making process; they indicate that trust mediates the relationship between virtual copresence and performance. It is therefore recommended that the efforts related to the design and adoption of communication systems for decision making teams strongly consider that virtual copresence potentially promotes both high levels of trust and high quality performance in virtual teams.     

Stimulating the Potential: Creative Performance and Communication in Innovation Teams

Creativity is essential to successful new product development efforts. Teams constitute the organizing principle in most modern innovation activities. Although creativity research has revealed many factors influencing individual creativity, little is known about how team‐level creativity is determined. Since the creative innovation task requires teams to combine and integrate input from multiple team members, the team's communication pattern is an important determinant of team creativity. Based on a sample of 44 NPD teams in eleven companies, this study examines the effects of team‐member communication on team creativity. It is found that both interaction frequency and subgroup‐formation of communication have a negative relationship to team creativity. Theoretical and practical implications are discussed, and further research is indicated.
