Boundary Issues in Global Virtual Teams

The purpose of this dissertation is to develop a better understanding of boundary issues in global virtual teams, especially in higher education settings. Although previous research in the past decade has studied various aspects of global virtual teams, there is no comprehensive review of boundary issues and their impact. This dissertation addresses these limitations in previous research through a systematic investigation of boundaries issues in global virtual teams. First, it surveys previous research to draw a comprehensive picture of how global virtual teams have been studied and builds a classification system of boundary issues. The relationship between boundary issues and team performance is then investigated in a quantitative study of China-US virtual teams in engineering education. Boundaries and the interaction among them are further described in a multi-perspective qualitative case study of engineering students participating in global virtual teams. The findings indicate that boundary issues were present individually and concurrently, and also interacted among one another to impact team collaborative learning. The dissertation also informs recommendations on team set up and team project design to enhance collaborative learning practice in higher education at a time when the engineering sector is becoming increasingly global. This dissertation provides a foundation for future research of the boundaries that affect virtual team performance in a global education environment

Collaborative distance: investigating issues related to distance factors affecting collaboration performance

Both organisations and individuals are using more collaborative work, across geographic, disciplinary and organisational boundaries, leading to increased demand for Information and Communication Technologies (ICT) to support a more effective and efficient distributed collaboration. This thesis presents an empirical study exploring various aspects related to collaborative distance in the context of innovation projects. It focuses on the investigation of issues related to distance factors that affect collaboration effectiveness and efficiency. A total of 14 focus group interviews, undertaken with 75 participants in a comparative study of 14 project cases, revealed sufficient evidence on distance factors in the context of mixed (face-to-face and online or virtual) collocation modes. The results confirmed the positive role of collaboration technology for compressing geographical and temporal types of distance; other distance types were also bridged, however, other distance types were created. This empirical study aims to enlarge the academic understanding of distance factors by disambiguating their description and deciphering their role in the collaboration process, and clarifying the reasons for the use and improvement of collaboration technology for overcoming collaborative distances. It also confirms that distance factors raise collaboration barriers, and reveals that they disturb the collaboration mechanics by hindering knowledge workers’ capacity to reach a mutual understanding. Such findings have deep implications for the future enhancement of collaboration technology to fill the current gaps in distributed collaboration, also called e-Collaboration

Integrating Culture in Designing Groupware Applications as Contribution to Intercultural Collaboration Technology

Many industries are now dealing with the issue of globalization and emphasized the need of the influence of a global marketplace. Globalization extends computing, information, and communication technologies across an increasing number of cultural boundaries, generating a corresponding need for cross-cultural partnerships. Due to globalization, global virtual teams with members from different cultures are an emerging trend. The use of collaborative projects is increasing and affects users’ approach to work in a collaboration application, so called groupware. Groupware is a collaboration application designed to support the work of groups. It can allow globalized industries and organizations greater coordination of activities, reducing and eliminating time and geography barriers, and speeding the decision making process. Groupware users are influenced by demographic, social, cultural, psychological and contextual factors, which complicate the understanding of groupware use. The different backgrounds of users may cause them to have different expectations and attitudes towards their acceptance of using groupware. In order for a specific technology application to be useful, applying technology appropriately to the needs of its users is very important. Groupware that only determines structures of communication, such as floor control, turn-taking, communication procedures, and so on may disadvantage and discourage people from different cultural communication styles. These factors should be considered by designers when designing such groupware application in order to be successful. A groupware targeted for multicultural users should have a flexible intercultural support which means can adaptively manage the cultural differences of its users. A great attention should be given for the cultural element in creating products and interfaces that are culture “fit” to its users. Understanding these social and cultural differences is very important in groupware to support cross-cultural collaboration. This dissertation offers solutions to the design issues in groupware for multicultural user to avoid a failed system. Most software engineers when designing applications focuses only on the technical issues and fail to include the social factors that are very important in developing technologies that serves as social applications. Therefore in this dissertation, two extension layers are introduced extending the well know 7-layers OSI model. These two extension layers of ISO/OSI layer model mainly focus on the end-user of the applications consisting of social layer as the 8th layer and cultural layer as the 9th layer, used to link applications to human needs. The social layer representing the support of groups and the cultural layer representing the communication as it is influenced through different cultural backgrounds of users using the tools. These extension layers help software engineers to develop applications within a socio-cultural deployment context. The Technology Acceptance Model (TAM) is extended in this dissertation to understand the mechanism by which cultural differences could explain users’ behaviors toward the acceptance of groupware applications as a remote collaboration tool for global virtual team. A new approach, called culture-centered design and cultural engineering as the anchor for groupware development in multicultural context is introduced to define the requirements, features and functions that should be included in groupware as an intercultural collaboration tool. An expert system to be embedded in groupware, called Intercultural Collaboration Environment Expert System (ICEES), is also developed in the context of a cross-cultural collaboration and is expected to support PASSENGER 2, a new innovative groupware that is currently under development at the Institute of Computer Engineering, University Duisburg-Essen. ICEES provide advice to the group in selecting the most suitable tools for enhancing the group discussion. This dissertation is expected to serve as a benchmark for future research on groupware design for multicultural users across different countries

An exploratory study of a virtual partnership for building capacity in a tertiary education institution

Collaborative partnerships aimed at strengthening institutional capacities are a long established trend in academia. Recent developments in Information and Communications Technologies (ICTs) have fostered a renewed interest in collaborative initiatives in the academic sphere, however, and at the same time, have created new ways of working together. Current research models do not provide sufficient methods to guide collaborations in capacity-building processes in virtual environments, especially in contexts associated with inadequate resources. Conceptual tools are therefore needed to guide the implementation of partnerships that use technology to mediate capacity building in these contexts. This research study was aimed at understanding whether and how virtual partnerships can be used to facilitate capacity building in tertiary education institutions in the SADC region. It is based on a single case study of the SANTED Virtual Classroom Project, a partnership between the Departments of Computer Science at Rhodes University (RU) and the University of Namibia (UNAM). In the project, ICTs were used to mediate the process of building teaching and research capacity in the department at UNAM. The dynamics of the partnership are explored as the implementation process developed over a period of three years. The research adopted a sociocultural perspective in the analysis of the project‟s implementation. It uses activity theory and the notion of communities of practice as conceptual frameworks to explore how the two departments organised themselves and how they harnessed the virtual environment to enable the capacity-building partnership. Activity theory provided a lens to understand the complex relationships between the different elements of the partnership activities mediated by technological tools. The concept of communities of practice, on the other hand, enabled participants‟ progress to be analysed, as they went through the various transition stages of the capacity-building process. The thesis identifies the following four categories of challenges inherent in the implementation of virtual partnerships: infrastructural, institutional, cultural and individual expectations. It also emphasises the need for identifying the different transition stages corresponding to the levels of participation in the capacity-building process. The thesis recommends that the implementation of virtual partnerships for capacity building purposes in the SADC region must focus on: identifying the appropriate capacity building strategies at Abstract ii each transition stage; finding appropriate, light-weight virtual classroom solutions; identifying appropriate pedagogic models to suit available technology; addressing systemic tensions that can arise as a result of different institutional cultures; and developing and nurturing virtual communities of practice to ensure sustainability. The research findings contribute to the body of knowledge exploring the use of technologies to develop and strengthen human resource capacities in developing contexts in a sustainable way. More importantly, it contributes to the literature on collaborative virtual partnerships in the SADC region, and demonstrates one way in which the operations of such a partnership may be supported in similar contextsAdobe Acrobat 9.53 Paper Capture Plug-i

Modelling Software Project Management Complexity - An Assessment Model

During the last years, more and more business use projectised organisation as an organisation structure to tackle complex problems needed for the implementation of their strategic objectives. A significant number of these projects were/are challenged or even failed to meet their initial requirements in terms of cost, time and quality. This phenomenon is more intense in software projects due their special characteristics sourcing from the dynamic and continuous changing environment they operate and the nature of the software itself. Most of these failures were attributed to complexity that exists in various forms and levels at all projects. Many studies attempted to identify the sources of project complexity and define an appropriate complexity typology for capturing it. However, most of these studies are theoretical and only a limited number is proposing models capable to evaluate or measure project complexity. This research, acknowledges the endogenous character of complexity in projects but instead of trying to identify complexity dimensions of this complexity in projects, focuses on the complexity in the interfaces between project processes, project management processes and project managers, which consists of the critical point for successful project execution. The proposed framework can be used in order to highlight the most significant complexity areas either organisation specific or project specific, providing in that way the necessary awareness for better, efficient and effective project management. The approach followed in framework design, identifies the variation of perception of complexity between different organisations. Allow organisations to evaluate complexity of projects and provide them with an important information that will assist project selection process. Identifies the significance of peoples’ knowledge and experience and generally the maturity/capabilities of an organisation in management in order to handle complexity, as this was revealed through the findings of this research. Furthermore, considers complexity as variable that can be measured and propose a model for it. To implement this framework, an extended literature review was initially performed, for identifying the complexity factors sourcing from project management aspects. Subsequently, statistical methods for processing and refining the identified factors were used, resulting to the final set of measures used in the framework. Finally, the proposed model was validated through the appliance of case study methodolog
