Abstract. More and more software projects use Commercial-Off-The-Shelf (COTS) components. Although previous studies have proposed specific COTSbased development processes, there are few empirical studies that investigate how to use and customize COTS-based development processes for different project contexts. This paper describes an exploratory study of state-of-thepractice of COTS-based development processes. Sixteen software projects in the Norwegian IT companies have been studied by structured interviews. The results are that COTS-specific activities can be successfully incorporated in most traditional development processes (such as waterfall or prototyping), given proper guidelines to reduce risks and provide specific assistance. We have identified four COTS-specific activities – the build vs. buy decision, COTS component selection, learning and understanding COTS components, and COTS component integration – and one new role, that of a knowledge keeper. We have also found a special COTS component selection activity for unfamiliar components, combining Internet searches with hands-on trials. The process guidelines are expressed as scenarios, problems encountered, and examples of good practice. They can be used to customize the actual development processes, such as in which lifecycle phase to put the new activities into. Such customization crucially depends on the project context, such as previous familiarity with possible COTS components and flexibility of requirements. 1

We present a tactical decision model for order acceptance and capacity planning that max-imizes the expected profits from accepted orders, allowing for aggregate regular as well as non-regular capacity. The stream of incoming order arrivals is the main source of uncertainty in dynamic order acceptance and the company only has forecasts of the main properties of the future incoming projects. Project proposals arrive sequentially with deterministic inter-arrival times and a decision on order acceptance and capacity planning needs to be made each time a proposal arrives and its project characteristics are revealed. We apply stochastic dynamic programming to determine a profit threshold for the accept/reject decision as well as to deterministically allocate a single bottleneck resource to the accepted projects, both with an eye on maximizing the expected revenues within the problem horizon. We derive a number of managerial insights based on an analysis of the influence of project and environ-mental characteristics on optimal project selection and aggregate capacity usage.

Keywords: The interaction between a complex socio-economic environment and the extremely fast pace of development of new telecommunication technologies and services justifies the interest in using multicriteria evaluation in decision making processes associated with several phases of network planning and design. Based on an overview of current and foreseen evolutions in telecommunication network technologies and services we begin by identifying and discussing challenges and issues concerning the use of multicriteria analysis (M.A.) in telecommunication network planning and design problems. Next we present a review of contributions in these areas, with particular emphasis on network modernisation planning and routing problems. We will also outline an agenda of current and future research trends and issues in this application area of multicriteria modelling.

This paper presents N-Site, a distributed consensus building and negotiation support system, which is used to provide geographically dispersed teams with agile access to a Web-based group decision support system. Four teams located in France, Mexico, the Ukraine, and the United States participated in the N-Site project. Each team was required to research the problem using the World Wide Web (WWW). With this background, each team identified opportunities, threats and alternatives as a basis for developing a response to the Cuban Missile Crisis that confronted President Kennedy in October 1962. The strategic assessment model (SAM) (M. Tavana, J. Multi-Criteria Decision Anal. 11 (2002) 75–96; M. Tavana and S. Banerjee, Decision Sci. 26 (1995) 119–143.) was used by each team to choose a strategy that best fit the team’s perspective. SAM and WWW enabled the teams to evaluate strategic alternatives and build consensus based on a series of intuitive and analytical methods including environmental scanning, the analytic hierarchy process (AHP) and subjective probabilities. The WWW was used to achieve interaction among the international teams as they attempted to negotiate a decision framework and select a diplomatic response. The project was assessed with a Web-distributed survey instrument. This use of the WWW has implications for international diplomacy as well as global business.

The purpose of this paper is to illustrate how the analytic hierarchy process (AHP) can be applied to those situations in higher education where a group must evaluate a large number of alternatives. The suggested approach is illustrated using a case study that considers the evaluation of academic research papers at Villanova Univer-sity. Following the discussion of this successful case study, a second example indi-cates how the AHP can be applied to the more complex problem of institution-wide strategic planning. These examples clearly demonstrate that the AHP approach is a versatile tool that can be applied to a wide range of important academic evaluation problems. Limited internal resources and heightened competition for external resources require that many universities critically examine their decision-making pro-cesses. White (1987) reviewed the use of analytical support tools within the academic setting. He found that reported applications varied across the spec-trum of decision-making activities and include planning, resource allocation, evaluation, budgeting, and scheduling. However, at the time of this study, only a few successful decision support systems had been developed and used. Previously, the available decision support tools generally assumed the point of view of a single decision maker evaluating a set of alternatives with respect to one overriding criterion, such as cost or time. However, many important decision-making problems in academia are made by committees or groups where a number of distinct viewpoints emerge and a final decision is possible only after a consensus is reached. Today, flexible, easy-to-use, Windows-based software packages are available to support group-level decision making when multiple evaluation factors and viewpoints are present. One such methodology,

Abstract. To gain competitive advantages software organizations are forced to develop systems quickly and cost-efficiently. Reusing components from thirdparty providers is one key technology to reach these goals. These components, also known as OTS (Off-the-Shelf) components, come in two different types: COTS (Commercial-Off-The-Shelf) and OSS (Open–Source-Software) components. However, the reuse of pre-fabricated components bears one major question: How to adapt development processes/methods with refer to system development using OTS components. To examine the state-of-the-practice in OTS component-based development a survey on 133 software projects in Norway, Italy and Germany was performed. The results show that OTS-based development processes are typically variations of well-known process models, such as the waterfall- or prototyping model, mixed with OTS-specific activities. One reason might be that often the process is selected before the use of OTS components is considered. Furthermore, the survey shows that the selection of OTS components is based on two processes: “Familiarity-based ” and “Internet search-based”. Moreover, it appears that the lifecycle phase to select OTS components is significantly correlated with a project members ’ previous familiarity with possible OTS candidates. Within this paper, we characterize the state-of-the-practice concerning OTS processes, using seven scenarios, and discuss how to decide or modify such processes and how to select OTS components. 1

This paper develops a new model for the evaluation of technological risk which enables the integration of a rigorous process for the capture of quantitative/qualitative data with a newly devised subjective technique, Subjective Estimated Effect Technique (SEET). In this paper it will be shown how this new model can address the dynamic aspects of the evaluation of risk in the management of human, social, organisational, technological, and cultural issues that impact the success of any Information Technology (IT) transfer.
