- A Qualitative Approach to the Evaluation of Expert Systems Shells. Slawson, Dean A. And Others Case Studies Computer Software Data Analysis Data Collection Evaluation Methods Expert Systems Qualitative Research Research Design This study explores an approach to the evaluation of expert system shells using case studies. The methodology and some of the results of an evaluation of the prototype development of an expert system using the shell "M1" are detailed, including a description of the participants and the project, the data collection process and materials, and data interpretation. A list of application characteristics by which a user of a case study library might search for relevant cases is presented. The benefits of the case study method are then discussed, including the positive effect of the presence of an outside observer on the process of developing the expert system, and a detailed description is provided of the problem setting, the shell, and the process of using it on a real expert system development problem. The pitfalls of the case study method are also noted, including the failure to generate useful quantitative metrics or to clearly identify any one shell attribute as the cause of the outcomes observed. A discussion of directions for future work concludes the report. (10 references) (EW)
