IT portfolio decision-making in local governments: Rationality,politics, intuition and coincidences

IT project portfolio management (IT PPM) has evolved into a significant area of research interest, but we know little about IT PPM practices in public sector organizations. Therefore this article investigates decision-making processes in the IT PPM practices of local governments, and discusses how these practices match the normative advice proposed by the IT PPM literature. We rely on decision-making theories together with case-studies of four Danish local governments. We find that politics, intuition and coincidence play a crucial role in IT PPM decision-making, while technical rationality (as proposed by the IT PPM literature) plays a minor role. Our account also reveals how the decision-making practices create IT portfolio problems and in some aspects is considered to have a negative impact on the outcome of e-government investments. Our analysis and previous research into decision-making allows us to argue that implementing textbook-IT PPM is difficult because it relies on decision-making ideals that are incompatible with organizational contexts and individual behavior in these organizations. Instead of radically changing decision-making styles, the organizations might be better off improving IT PPM practice within the boundaries of their existing decision-making styles, and the IT PPM literature might improve support for practitioners by incorporating other decision-making styles besides technical rationality.

Contents and time sensitive document ranking of scientific literature

A new link-based document ranking framework is devised with at its heart, a contents and time sensitive random literature explorer designed to more accurately model the behaviour of readers of scientific documents. In particular, our ranking framework dynamically adjusts its random walk parameters according to both contents and age of encountered documents, thus incorporating the diversity of topics and how they evolve over time into the score of a scientific publication. Our random walk framework results in a ranking of scientific documents which is shown to be more effective in facilitating literature exploration than PageRank measured against a proxy gold standard based on papers’ potential usefulness in facilitating later research. One of its many strengths lies in its practical value in reliably retrieving and placing promisingly useful papers at the top of its ranking.
