This paper is about an intervention that was initially concerned with physical processes but which required consideration of information flows and culture. The investigation was intended to improve the processing strategy and operations of an organization in the East Slovakian Coal Industry. Simulation modelling was used to help the debate, and it helped reveal issues of misunderstanding within the organization and poor communication that led to misallocation of resources. New ways of approaching the process were proposed that would lead to significant reductions in coal waste.

Business-process reengineering (BPR), like computer information systems development (ISD), deals primarily with process and contains only weak facilities for addressing structure and culture. Manufacturing and ISD have strong roots in the functionalist traditions of natural science, and in a cultural environment their engineering stance deals poorly with obstacles to change. While the structured, or “hard,” engineering approaches have given rise to successful developments, they have not always proved effective. In ISD, the hard engineering methods have a tendency to redefine information systems problems as problems of technical development, and similarly in engineering contexts, BPR risks becoming too focused on technical processes. However, failure to gain commitment and a sense of ownership in new processes is a cause of failure in both BPR and ISD. This article explores a case study where both technical and human issues must be addressed—the extension of student record processing within a university. In this study, the BPR requirement is seen to arise from the users of the information system rather than as an imposed managerial imperative. The use of total systems intervention (TSI) and interactive planning (IP) enabled the immediate technical problems to be separated from underlying BPR requirements and from the need to gain commitment to change. Thus, unnecessary technical effort and the risks of failure from resistance to change were avoided. From the findings of this intervention, it is argued that the wider application of TSI provides a framework within which managerially perceived needs can be translated into a grassroots commitment.

This paper is an account of a case intervention, undertaken at a National Health Service hospital outpatients department. The intervention utilised a soft systems approach, to address gaps between the customers' and providers' expectations, and simulation was used within this framework. A procedure to reduce unexpected non–attendance of patients has been implemented. Patient bookings are now scheduled according to simple rules, with the result that in–clinic waiting times have been reduced. A model of the intervention process has been accepted by the key stakeholders as a sensible framework for continuing investigations. More widely, the participants increased their knowledge of their own systems. The results from the case suggest that the time spent following this approach may be worthwhile in some interventions, but there are concerns relating to the time needed, and the cost of such an approach. The paper provides a critique of the framework and the intervention, and concludes that this approach is probably viable in unpaid, collaborative, investigations where there is little or no cost. However, time and cost may prove prohibitive in the case of paid consultancy.

Expert systems have become the more acceptable face of the much mooted “artificial intelligence” of the 1980s. A survey of UK organizations was undertaken in order to determine the usage rate and the main applications of expert systems. The responses indicate that very little use is being made of the available technology, and that where expert systems are used, they are often utilized in routine roles. Interviews were carried out with 12 high‐level managers in medium and large organizations to ascertain the possible results of poor or little use of expert systems and why organizations are reluctant to use them. The consensus is that, on a global scale, UK firms may lose sustained competitive advantage if they do not make the best use of the technology available.

The effective and efficient provision of out-patient services may be assisted by the appropriate use of discrete event simulation. Resource use must be carefully monitored and suitable control actions must be taken, if service level and quality are to be maintained, whilst keeping cost increases to a minimum. In itself, simulation provides no means by which system activities may be identified. The use of soft systems methodology as a tool to aid in activity identification for simulation modelling is being explored.The investigation focuses on the effects the participative nature of soft systems methodology has on the acceptability of a simulation model. This case study forms part of a research objective of developing a generic approach to link soft systems methodology and simulation. Its aim is to provide analysts and managers with a process which may assist in planning strategies for health care.

Although informed approaches from an interpretivist perspective have been widely promoted over the last two decades information systems development is largely informed by a functionalist perspective, into which human-centred or interpretivist issues are incorporated as they are seen to be required. By treating such developments as critically informed social systems, this paper offers an alternative viewpoint. Firstly, a theoretical justification for such an approach is offered, drawing on developments in Critical Management Science, themselves based on a strand of Critical Social Theory. Secondly, an action research-based intervention is detailed, demonstrating the practical applicability of such an approach, an applicability that has hitherto been questioned. The outcome is a synthesised approach to operational and strategic information systems development, within a critical framework, which, it is argued, offers a greater potential for success than the currently promoted approaches.
