publication titleSupporting Wicked Problems with Procedural Decision Support Systems
publication descriptionWicked problems are immensely complex problems that do not lend themselves to resolution through traditional problem-solving approaches. This capriciousness is particularly troublesome for organizations that encounter such problems due to their very nature being highly prone to fluctuation. Further, any attempts to resolve wicked problems tend to be irreversible - for better or for worse.
Decision support systems (DSSs) have long been hailed as a panacea of sorts for highly complex problems due to their ability to assist in storing, retrieving, and manipulating information to arrive at a decision. However, traditional DSSs, being originally aimed at semi-structured problems, are rendered almost ineffectual in the face of the high levels of complexity inherent in wicked problems. Consequently, this paper outlines the argument that posits procedural rationality as an alternative underlying mechanism for developing DSSs for wicked problems. An empirical literature review is utilized to locate the required characteristics of such a DSS, to evaluate cognizance thereof in the research, and to present an integrated model for the design, development, and utilisation of procedural DSSs specifically for resolution of wicked problems.

publication titleTowards a Decision Support System for Wicked Problems: A Literature Analysis
publication descriptionWicked problems are complex and challenging to solve. This is partially due to changing requirements in the problem definition, as well as the fact that proposed and implemented solutions are generally significant in effect and irreversible in nature. In contexts where the consequences of a solution to a wicked problem are comprehended as being critical to an organisation's survival, such firms may elect to build or acquire a decision support system (DSS) to assist decision makers with the vital task of resolving such problems. DSSs have been shown to provide some benefit to users by neutralising cognitive biases as well as improving effectiveness and efficiency of decision making. However, it has been argued that traditional variants of these tools are seldom appropriate for addressing wicked problems, and as such, an alternative approach to solving wicked problems is required to that of typical
decision making problems.
The conceptualisation of procedural rationality as a suitable underlying approach for support of wicked problems has been argued in a number of studies. Such research asserts that the approach focusing on the process of decision making as opposed to the substance of the decision process. In order to investigate the nature of wicked problems and decision support in these contexts, a primarily qualitative literature study was completed, and findings were integrated to synthesise a model for procedural decision support.

publication titleMaps as a technique for visualizing load-shedding schedules
publication descriptionThe South African electrical utility, Eskom, is faced with the problem of communicating information about the times and locations for rotational load-shedding. This paper challenges whether the current presentation format is an optimal communication medium. An alternative communication medium is proposed in the form of a map-based schedule. The value of maps as communication devices is determined by means of a qualitative study into the areas affecting the comprehension and construction of maps. Following from this a prototype map-based schedule is developed as a proof of concept in order to determine its feasibility as a communication medium and case studies are employed to qualitatively evaluate the effectiveness of maps as a technique for visualizing load-shedding schedules. It was found that maps present advantages over the current table-based schedule provided by Eskom. However it is also clear that the proposed solution is not a panacea for all potential tasks. While new spatial information is made available, a map-based approach results in the loss of significant temporal information. Maps and tables were found to fulfill complementary roles, leading to the recommendation that they be employed simultaneously as load-shedding schedule communication devices.
