Information System Development Methodologies Essay

Information System Development Methodologies - Essay Example Information System Development Methodologies The comparison of information system development methodologies is also established through either people oriented or goal oriented evaluation frameworks. The comparison of information system development strategies is effective if it helps in ensuring that developed systems are in line with the customer requirements and user needs. The contemporary organizations, departments, agencies and business environments have demonstrated increased adoption and application of information and communication technologies in various processes and activities. This is motivated to the benefits of efficiency and effectiveness which are associated with the use of technology. As a result, information systems have been developed to facilitate various processes within organizations such as communication and exchange of information and data. Hughes (2006, p. 36) says that the adoption and implementation of information and communication technology is achieved through various methodologies of system developme nt. This paper gives a critical analysis, evaluation and discussion of the existing comparison frameworks for information system development methodologies. The paper further evaluates the effectiveness of these frameworks in relation to their effectiveness. In addition, a detailed discussion of the criteria used in comparing the information system development comparison frameworks is given. Comparison frameworks for information system development are focused at drawing differences and similarities among the various methodologies for system development. ... Lindstrom and Jeffries (2004, p. 45) point out that iterative and incremental frameworks are used in comparing the various methodologies in information system development. The iterative and incremental system development frameworks are part of the agile approach to system development. The agile frameworks are based on the premise that effectiveness in information system development is achieved through a combination of two approaches. These approaches are system development in small portions in an incremental manner and through repeated cycles which is referred to as iterative approach to the system development. Rob (2006, p. 32) says that the commonly used agile methods in system development include Dynamic Systems Development Method (DSDM), Extreme Programming (XP) and Adaptive Software Development (ASD). The organization of DSDM is presented in Appendix I. According to Sol and Stojanovic (2003, p. 20), the iterative and incremental (agile) framework focuses in interactions and indi viduals within an information system. This is opposed to focus on tools and processes of system development. In this regard, it is arguable that the interactive and incremental framework is effective in the analysis of the development process of information systems. This is due to the fact that this framework presents a development approach in relation to its ability to establish the interaction between various elements of an information system. The iterative and incremental framework therefore allows system developers to ensure that the tools and processes of an information system are coherently integrated in the execution of the functions of an information system. Through this framework a mere focus on
