    Often, it has been observed that telecommunication infrastructure development and economic growth proceed together. While this relationship has been studied in the context of developed (OECD) countries, in this study, we investigate this simultaneous relationship between telecommunications and the economic growth, using data for developing countries. Using 3SLS, we estimate a system of equations that endogenize economic growth and telecom penetration (respectively production function and demand for telecom services), along with supply of telecom investment and growth in telecom penetration. We estimate this system of equations separately for main telephone lines and cell phones. We find that while traditional economic factors explain demand for main line phones, they do not explain demand for cell phones. We also find significant impacts of cellular services on national output, when we control for the effects of capital and labour. The impact of telecom penetration on total output is, however, significantly lower for developing countries than that reported for OECD countries, dispelling the convergence hypothesis.Telecommunication ; Infrastructure ; Economic growth ; Reverse causality ; Developing countries

    The merging of computers and telecommunications technologies is facilitating people to communicate effectively across geographically dispersed locations. Growth of the Internet has made it possible for organizations to use the network as the resource to interconnect people and various organizational units. Advances in wireless technologies have increased mobility of individuals and hence the ability to work from remote locations. In this paper, we look at whether telecommunications and computer connectivity allow people to live in suburban locations, farther from center of city where their offices are located. The findings from the research will help us analyze whether people prefer to live outside the city limits and telecommute if adequate telecommunications and information technologies are available

    Analysis of Telecommunications Infrastructure for Internet Access in Developing Countries

    Internet has seen tremendous growth in terms of number of hosts and number of users in recent years. Despite this growth, Internet is not universally available. Most of the Internet activity takes place in the developed nations. Even in places where Internet connectivity is available, users are constrained to use low bandwidth connections because of the limitations of the access network that connects them to the backbone networks. This problem, known as “last mile” problem in telecommunications has attracted the attention of researchers. Bell (1996) addresses the last-mile problem for Internet connectivity as applicable to developed countries and prescribes possible wireline based access network solutions. Khasnabish (1997) addresses both wired and wireless access networks, again in the context of developed economies. Chatterjee (1997) briefly discusses this problem for providing broadband access. Developing countries have very low teledensities and have inferior telecommunication infrastructure. The technology alternatives suitable for developed nations are not suitable for developing countries. Paulraj (1995) addresses the last-mile problem in developing countries and suggests wireless solutions for basic telephony based services. In this paper we extend the model described in (Paulraj, 1995) to address additional factors to be considered for the evaluation of access network alternatives for providing Internet connectivity in developing countries. We investigate which access network technology is suitable for Internet connectivity for residential users in developing countries. Preliminary studies indicate that wireless access solutions have an edge over wireline technologies

    Bringing Global Sourcing into The Classroom: Experiential Learning Via a Global Software Development Project

    The growing trend in offshore software development has imposed new skills requirements on collaborating global partners. In the U.S. this has translated into skill sets that include communications, project management, business analysis, and team management. In a virtual setting, these skills take on a complex proportion. This paper describes an educational initiative in offshore software development between undergraduate students enrolled in a project management course at Marquette University, USA and graduate business students enrolled in an Information Systems Analysis and Design course at Management Development Institute, India. The course replicated an offshore client/vendor relationship in a virtual setting. For faculty considering such initiatives, this paper describes the setting and factors critical to success of this initiative and cautions against others that can be detrimental to such an effort

    Bringing Global Sourcing into the Classroom: Experiential Learning via Software Development Project

    Global sourcing of software development has imposed new skill requirements on Information Technology (IT) personnel. In the U.S., this has resulted in a paradigm shift from technical to softer skills such as communications and virtual team management. Higher education institutions must, consequently, initiate innovative curriculum transformations to better prepare students for these emerging workforce needs. This paper describes one such venture between Marquette University (MU), U.S.A. and Management Development Institute (MDI), India, wherein IT students at MU collaborated with Management Information Systems (MIS) students at MDI on an offshore software development project. The class environment replicated an offshore client/vendor relationship in a fully virtual setting while integrating communications and virtual team management with traditional IT project management principles. Course measures indicated that students benefited from this project, gained first-hand experience in the process of software offshoring, and learned skills critical for conduct of global business. For faculty considering such initiatives, we describe the design and administration of this class over two semesters, lessons learned from our engagement, and factors critical to success of such initiatives and those detrimental to their sustenance

    Control, Process Facilitation, and Requirements Change in Offshore Requirements Analysis: The Provider Perspective

    Get PDF
    Process, technology, and project factors have been increasingly driving organizations to offshore early software development phases, such as requirements analysis. This emerging trend necessitates greater control and process facilitation between client and vendor sites. The effectiveness of control and facilitation has, however, not been examined within the context of requirements analysis and change. In this study, we examine the role of control and facilitation in managing changing requirements and on success of requirements gathering in the Indian offshore software development environment. Firms found that control by client-site coordinators had a positive impact on requirements analysis success while vender site-coordinators did not have similar influence. Process facilitation by client site-coordinators affected requirements phase success indirectly through control. The study concludes with recommendations for research and practice

    Project Quality of Offshore Virtual Teams Engaged in Software Requirements Analysis: An Exploratory Comparative Study

    Get PDF
    The off-shore software development companies in countries such as India use a global delivery model in which initial requirement analysis phase of software projects get executed at client locations to leverage frequent and deep interaction between user and developer teams. Subsequent phases such as design, coding and testing are completed at off-shore locations. Emerging trends indicate an increasing interest in off-shoring even requirements analysis phase using computer mediated communication. We conducted an exploratory research study involving students from Management Development Institute (MDI), India and Marquette University (MU), USA to determine quality of such off-shored requirements analysis projects. Our findings suggest that project quality of teams engaged in pure off-shore mode is comparable to that of teams engaged in collocated mode. However, the effect of controls such as user project monitoring on the quality of off-shored projects needs to be studied further

    Flexible Global Software Development (GSD): Antecedents of Success in Requirements Analysis

    Globalization of software development has resulted in a rapid shift away from the traditional collocated, on-site development model, to the offshoring model. Emerging trends indicate an increasing interest in offshoring even in early phases like requirements analysis. Additionally, the flexibility offered by the agile development approach makes it attractive for adaptation in globally distributed software work. A question of significance then is what impacts the success of offshoring earlier phases, like requirements analysis, in a flexible and globally distributed environment? This article incorporates the stance of control theory to posit a research model that examines antecedent factors such as requirements change, facilitation by vendor and client site-coordinators, control, and computer-mediated communication. The impact of these factors on success of requirements analysis projects in a “flexible” global setting is tested using two quasi-experiments involving students from Management Development Institute, India and Marquette University, USA. Results indicate that formal modes of control significantly influence project success during requirements analysis. Further, facilitation by both client and vendor site coordinators positively impacts requirements analysis success
