The purpose of this research was to Wll a gap in the literature pertaining to the inXuence of project uncertainty and managerial factors on duration and eVort estimation errors. Four dimensions were considered: project uncertainty, use of estimation development processes, use of estimation management processes, and the estimator’s experience. Correlation(More)
Producing accurate and reliable project cost estimations at an early stage of a project’s life cycle remains a substantial challenge in the information technology field. This research benchmarks the performance of various approaches to estimating IT project effort and duration. Empirical data were gathered from various ‘‘real-world” organizations including(More)
This paper presents a methodology for the analysis of the linkage among the processes in an organization. The methodology has three main steps: model construction; connectivity analysis; and structure analysis. The model construction step generates a linkage matrix which is used in the following steps. The connectivity analysis is based on linkage(More)
We describe the application of two variations of agglomerative clustering to the analysis of planning data for an organization-wide information system design project. One algorithm used similarity as a measure of distance, while the other is based on the extent of inclusion of an object by another. The two algorithms take into account the graduated nature(More)
