Validating a model: the expert systems research approach.
The nursing profession is invariably resorting to the use of models to depict the key facets and relationships that are being uncovered through research. The expert systems approach to model validation incorporates into research methods a process authenticated by the disciplines of engineering and information systems. The seven-step process developed for a computer expert systems approach has been transformed into a Nine-Stage Schematic of the Process for Validating System Models. This article proposes the expert systems research approach to model validation as a means of clarifying and defining models within the discipline of nursing. This process was used to validate Boswell's Model of the Structure of Knowledge for Nursing, and the process conducted for this model will be discussed as a case study of the use of the expert systems approach for model validation.
