The Effects of Electronic Collaboration in Distributed Project Management

Abstact The emergence and widespread use of collaborative technologies for distributed project management has opened up opportunities for off-shore outsourcing and collaborative development. However, most tools and techniques for project management focus on on-site, long term relationships and sourcing strategies at a time when inter-organizational relationships are becoming more dynamic and geographically dispersed. This paper uses grounded theory to analyze data on virtual teams' projects. The analysis uncovers “effects” in the way in which distributed projects are managed. These effects relate to coordination, communication and adaptation to distributed electronic work environments. Following an analysis of these electronic collaboration “effects”, a model for distributed project management is presented.

Coveted or Overlooked? The Psychology of Bidding for Comparable Listings in Digital Auctions

This article elaborates on, and provides evidence of the herd behavior bias -- the tendency to gravitate toward, and bid for, auction listings with one or more existing bids, ignoring comparable or even more attractive unbid-for listings available at the same time -- exhibited by buyers in digital auctions. Some listings attract many bidders and become coveted, the center of bidding attention, while other equivalent or even superior listings are overlooked, receiving no bids at all. Empirical analysis using data from digital auctions across different product categories shows that this herd behavior bias is attenuated with increasing bid price, but increases with the difficulty of evaluating quality. The practical implications of these findings, and promising research opportunities in this area are also discussed.     

A Tale of Two Cities: Case Studies of Group Support Systems Transition

Research shows that, under certain circumstances, people using GSS can be substantially more productive than people who do not. However GSS has been slow to transition into the workplace. This paper argues that the Technology Transition Model (TTM) may be a useful way to explain this seeming paradox. The paper presents a case study of GSS transition in two organizations – one where a self-sustaining and growing community of users emerged, and one where it did not. Following TTM, it explores the frequency with which users perceived cognitive, economic, affective, political, social, and physical value from using the system. Comparison of the cases reveals differences in perceptions of value along several of these dimensions that are consistent with TTM. The findings suggest the model may be a useful way to explain the transition of collaboration technology, but more research will be required to test the model more rigorously.
