While the paradigm for organizations evolves into an information perspective and information systems’ (IS) role shifts from efficiency to effectiveness, among the top issues of IS management is measuring and improving IS effectiveness. This chapter offers an IS effectiveness evaluation methodology applied on a government organization in Turkey. IS maturity is taken as a reference for determining independent variables of the research. The chapter supports that “IS effectiveness” is a relative term conceptualized by organizational features. The case study suggests future research areas. A number of findings and propositions have been presented, including the alignment of technology and business process, integrating stakeholders’ trust and commitment, the significance of top management support, top-down vs. bottom-up approaches, which can enhance the adoption and institutionalization of information systems implementations within a government organization.

Traveler information has the potential to reduce travel times and improve their reliability. Studies have verified that driver overreaction from the dissemination of information can be eliminated through prediction-based route guidance that uses short-term forecasts of network state. Critical off-line tests of advanced dynamic traffic assignment–based prediction systems have been limited, since the system being evaluated has also been used as the test bed. This paper outlines a detailed simulation-based laboratory for the objective and independent evaluation of advanced traveler information systems, a laboratory with the flexibility to analyze the impacts of various design parameters and modeling errors on the quality of the generated guidance. MITSIMLab, a system for the evaluation of advanced traffic management systems, is integrated with Dynamic Network Assignment for the Management of Information to Travelers (DynaMIT), a simulation-based decision support system designed to generate prediction-based route guidance. Evaluation criteria and requirements for the closed-loop integration of MITSIMLab and DynaMIT are discussed. Detailed case studies demonstrating the evaluation methodology and sensitivity of DynaMIT's guidance are presented.

Selection Methodology

In the field of human cognition, thinking consists of problem-solving and decision-making. In cognitive thinking, top-down processing is an approach used by experts that enables them to solve problems and make decisions efficiently. This paper attempts to apply cognitive top-down thinking process to the concept evaluation of systems and their components. In the top-down concept evaluation approach, engineers first evaluate system concepts. Once a system concept is selected, engineers then identify system components (modules) that they can design independently for the chosen system concept. Engineers generate concepts for system modules and select one concept for each module. The objective of this paper is first to identify characteristics needed for a holistic and structured top-down concept evaluation methodology for a system and its components, and second to propose a research roadmap for establishing the proposed framework.

System Success

E-learning involves adopting and exploiting the potential of new, advanced Information Technology in development and delivery of education. In spite of a rapid growth in the e-learning field there still exists a range of issues facing the stakeholders of e-learning systems. One of the key issues is how to measure e-learning system success. Although considerable attention has been paid to the Information Systems success issue, there remain arguments about the factors which are most effective for measuring Information System success. The issue of measuring Information System success has an impact on evaluating e-learning systems success. This chapter aims to fill this void by proposing an evaluation methodology model to assess e-learning systems success. The contribution of this study is the proposed model to evaluate the success of e-learning systems. The model is based on a thorough review of the e-learning success literature and existing Information Systems success models.

The focus of this paper is on the modeling of application and business process in Cooperative Information Systems. Such processes use several resources and services to achieve a common, global system goal. We integrate the proposed concepts into the framework of a formal object-oriented specification language (TROLL). The goals of our approach are to provide additional modeling support for business and application processes, to explain these processes in the underlying framework and to couple tightly the modeling of global processes and the modeling of structural aspects of the system.

Legacy Information Systems

There is every indication that an object-oriented view of an information system is a solid foundation for understanding its legacy organization, for relating it to the environment in which it is embedded and for guiding its reengineering. In this paper we present a framework based upon the formal object-oriented specification language TROLL, which provides an object-oriented view of legacy information systems. The aim is to combine existing methods and keep results in a common and suitable description base which provides the appropriate form for deriving object specifications from the legacy IS. We usethe language TROLL not only as description language, but also as a framework to support the maintenance engineers in their reverse engineering tasks by giving hints about what to do next to complete the object specifications. The result of the approach is a formal object-oriented specification of the legacy IS that is suitable both for developing a new IS or for reengineering the legacy system.
