“…It was originally developed to represent the design knowledge of a complex process control system in the field of cognitive systems engineering (CSE). However, it has been effectively used for representing several other types of systems, which include library systems, information appliances, mobile phones, automobiles, and software systems, in the field of CSE and HCI (Hassenzahl 2000;Kwon et al 2007;Vicente 2002).…”

A great deal of study has been devoted to the problem of how to identify and categorize usability problems; however there is still a lack of studies dealing with the problem of how to diagnose the causes of usability problems and how to feed them back into design process.The value of classifying usability problems can be enhanced when they are interpreted in connection with design process and activities. Thus it is necessary to develop a systematic way of diagnosing usability problems in terms of design aspects and applying diagnosis results to improve design process and activities. With this issue in mind, this paper proposes a conceptual framework that supports a systematic classification and diagnosis of usability problems. This paper firstly reviews seven approaches to classifying usability problems.Then we point out the needs of adopting a model-based approach to classifying and diagnosing usability problems and of developing a comprehensive framework guiding the use of model-based approaches. We then propose a conceptual framework that specifies how a model-based classification and diagnosis of usability problems should be conducted and suggests the combined use of three different types of models, each of which address context of use, design knowledge, and design activities. Last we explain how a sound classification scheme of usability problems can be systematically developed and how the classification of usability problems can be connected to design process and activities on the basis of the framework.

“…Second, scenariobased analysis has a problem of incompleteness in dealing with the functions of software. To resolve these problems, Kwon et al [8] proposed a new method for generating and using scenarios organized in terms of abstraction structure of software and conducted a case study for testing the applicability of the method in a word processing program developed by a Korean company. Figure 4 shows the structure of the proposed method.…”

This study is aimed at developing a new method for modelling work domain knowledge with the combined use of abstraction hierarchy (AH) and living systems theory (LST). AH has been widely used as a work domain knowledge representation framework in the field of cognitive systems engineering and human-computer interaction, and its usefulness has been proved in a range of work domains. However, its effective use still remains a challenging issue. In order to address this problem, this study firstly points out several issues that can be raised in the use of AH and then explains why and how LST can give concepts and principles helpful to resolve them. The proposed method offers a framework for how to combine AH and LST, particularly to identify functional knowledge at higher abstraction levels. It also offers a process for modelling the knowledge of a work domain based on the combined use of AH and LST. The use of the proposed method is exemplified by modelling the knowledge of a simplified secondary cooling system of nuclear power plants. The proposed method is a new approach to refining the concepts of AH and modelling the knowledge of a work domain that humans should interact. It is believed that it will be a useful tool for knowledge modellers in identifying and modelling the knowledge of a work domain in terms of its functional structure. However, it should be noted that its usefulness can be limited to technology-oriented engineering systems; it would not be easily applied to human activity-oriented systems.
