Asynchronous Groupware Support Effects on Process Improvement Groups: An Action Research Study

WereportonastudyofsevenprocessimprovementgroupsintwoNewZealandorganizations. Allgroups followed the same group methodology and were facilitated by the researcher. The research approach used was action research. All groups interacted with the support of an e-mail conferencing tool. Six of the groups used e-mail conferencing as the main medium of interaction, and their members interacted through the e-mail conferencing system during 67 to 89 percent of the time. One of the groups conducted most of the discussion through a face-to-face meeting, using e-mail conferencing during only 18 percent of the time. Five of the groups were successful in generating and either fully or partially implementing process redesign proposals. Two of the groups failed to generate any process redesign proposal. Research data was collected through participant observation, unstructured and structured interviews, and in the form of e-mail discussion transcripts. This research data indicates that, while not having negative perceived effects on group effectiveness, asynchronous groupware support was perceived as increasing process adoption, hierarchy suppression, departmental heterogeneity, and contribution length, and decreasing discussion duration, cost, and interaction in process improvement groups

A model for the measurement and presentation of participation awareness in online groupware systems

The need to support effective group work in online environments has become a prominent issue in both education and enterprise. Universities continue to adopt constructivist-based learning strategies which see learners engage in group work to build knowledge, coupled with an increase in online and distance learners. In enterprise, where group or team based work is commonplace, the prevalence of the Internet has seen the emergence of teams that collaborate wholly or partially online. In response to this emergent need, groupware, software used to support online group work, has become widely used in both education and enterprise. Although based upon sound pedagogical principles, the use of groupware does not always meet expectations or compare favourably to face-to-face collaboration. The literature has identified the issue of awareness, defined by Dourish and Bellotti (1992, p. 107) as “an understanding of the activities of others, which provides a context for your own activity”, as a core factor in the effectiveness of groupware. Numerous awareness mechanisms have been developed and implemented into groupware applications, aiming to replace the information that is implicit in face-to-face collaboration, but largely absent in online environments. This study defined and modelled a new form of awareness named ‘participation awareness’, which aggregates and processes activity in a groupware environment in order to present a persistent display of group member participation. A field study was conducted, wherein university students utilised a groupware application named GroupShare to support group work required in their studies. GroupShare contained an implementation of a participation awareness mechanism, and participating students completed pre and post-usage questionnaires primarily concerning group work and the participation awareness mechanism. Further survey and observational techniques were also utilised to gather data. Two iterations of the field study were conducted, each running for one semester. Analysis of the data found that the participation awareness mechanism was well received, eliciting largely positive responses from a range of participant demographics, group dynamics and group work scenarios. Participant feedback was utilised to define and refine the constituents of participation awareness and create a generic model for its implementation as an awareness mechanism. The model outlines the steps and considerations required to capture and process activity within a groupware environment, and establishes three complimentary methods of presenting participation awareness. The author feels that the research was successful in creating and justifying a model of participation awareness which can be implemented in groupware environments and utilised in further research

Using natural user interfaces to support synchronous distributed collaborative work

Synchronous Distributed Collaborative Work (SDCW) occurs when group members work together at the same time from different places together to achieve a common goal. Effective SDCW requires good communication, continuous coordination and shared information among group members. SDCW is possible because of groupware, a class of computer software systems that supports group work. Shared-workspace groupware systems are systems that provide a common workspace that aims to replicate aspects of a physical workspace that is shared among group members in a co-located environment. Shared-workspace groupware systems have failed to provide the same degree of coordination and awareness among distributed group members that exists in co-located groups owing to unintuitive interaction techniques that these systems have incorporated. Natural User Interfaces (NUIs) focus on reusing natural human abilities such as touch, speech, gestures and proximity awareness to allow intuitive human-computer interaction. These interaction techniques could provide solutions to the existing issues of groupware systems by breaking down the barrier between people and technology created by the interaction techniques currently utilised. The aim of this research was to investigate how NUI interaction techniques could be used to effectively support SDCW. An architecture for such a shared-workspace groupware system was proposed and a prototype, called GroupAware, was designed and developed based on this architecture. GroupAware allows multiple users from distributed locations to simultaneously view and annotate text documents, and create graphic designs in a shared workspace. Documents are represented as visual objects that can be manipulated through touch gestures. Group coordination and awareness is maintained through document updates via immediate workspace synchronization, user action tracking via user labels and user availability identification via basic proxemic interaction. Members can effectively communicate via audio and video conferencing. A user study was conducted to evaluate GroupAware and determine whether NUI interaction techniques effectively supported SDCW. Ten groups of three members each participated in the study. High levels of performance, user satisfaction and collaboration demonstrated that GroupAware was an effective groupware system that was easy to learn and use, and effectively supported group work in terms of communication, coordination and information sharing. Participants gave highly positive comments about the system that further supported the results. The successful implementation of GroupAware and the positive results obtained from the user evaluation provides evidence that NUI interaction techniques can effectively support SDCW

Making Sense of the History of Information Systems Research 1975-1999: A View of Highly Cited Papers

In this paper, I analyze the history of IS research through the lens of 409 highly cited papers (i.e., papers with at least 100 Reuters Thompson Web of Science citations) pub­lished between 1975 and 1999. I focus on 1) what these highly cited papers are, 2) what they study, 3) who their authors are, and 4) where they were published
