Abstract

Knowledge‑based systems (KBSs) implement the heuristic human reasoning through specific techniques, procedures and mechanisms, in order to solve problems that do not have a traditional algorithmic solution. Research on this topic is being done in numerous organisations all over the world, from higher education laboratories to research institutes and software development organisations. A first research project, aimed at gathering information about the State‑of‑the‑Practice in building knowledge‑ based systems with practical applications, needed a preliminary study to ascertain if KBSs still exist today as a research topic, or the interest in them actually faded. The study was also required for finding organisations currently building KBSs for different domains. The project's aim was to catalogue the software andor knowledge engineering methods employed by the listed organisations, in order to draw a comprehensive image (State‑of‑the‑ Practice) of the field. The current paper contains the results of this preliminary study only. A second research project re‑used the results of the preliminary study, focusing on the study of KBSs' successful implementations as a basis for building a method that would allow practitioners to choose the most appropriate KM tools for each organisation's specific problems and situations. A trigger for this second project was the interest in studying the causes of KBSs rejection by the end‑users. An attempt to map the identified applications of KBSs to different phases of knowledge management lifecycle is also presented.

Abstract

IS evaluation exercises continued to engender scepticism. The evaluation of IS investment is considered a 'wicked problem' and there are good reasons for this judgement. The topic has attracted many researchers. There is a substantial body of literature on the problems of measurement and the inadequacies of traditional investment appraisal methods. A wide range of alternative tools has been proposed to replace these approaches. But many surveys of actual practice have established little evidence of their use. Reported IS evaluation practice appears to be relatively unsophisti‑ cated or absent in many organisations. This paper draws on existing literature and case material to analyse the problem facing organisations when planning an IS evaluation exercise. It argues that the factors that can undermine the effectiveness of IS evaluation projects pose ma‑ jor problems. Management apathy may be a rational response to a complex and difficult exercise that often yields little benefit to the organisation.

Abstract

Since the 1980s, a number of frameworks have been proposed for understanding the concept of information system (IS) failure. Two approaches to IS failures seem particularly important: the concept of Expectation Failure and the concept of Termination Failure. We argue that there is an extra dimension to the problem that is not covered by those descriptive models, which we call the Outsourced IS Failure (OISF). To explain the OISF we draw on agency theory, which views the problems that occur in outsourced environments as the results of three factors: goal differences, risk behaviour differences and information asymmetry. Although the (positivistic) agency theory has already been used to describe phenomena of failure in IT relations there is still a lack of empirical evidence. This paper brings the results of the attempts of falsification of the agency theory in situations of OISF. A positivistic case study research was conducted based on multiple cases in SMEs. The choice for qualitative research is based on the accessibility of well documented secondary data in litigation files of failed IS projects. Eight cases of IS project failures subject to litigation were selected. We conclude that the agency theory has strong prediction and explanation power for OISF. However some adjustments are needed to the agency theory. The theory seems to work in two ways, opportunistic behaviour is also observed on the side of the principal. The findings indicate that lack of trust is a prominent determinant for failure.
