dc.description.abstract In this study the development of a model of organisational effectiveness and its transpositioning, into a computer-assisted instrument that facilitates the assessment of organisational effectiveness of business corporations, is discussed. An extensive literature study is used to explore the effectiveness construct and to identify effectiveness criteria. Existing approaches, models and research results are critically evaluated and used in the construction of a provisional system-based model that comprises groups of input, transformation, outcomes, attributes and community-related effectiveness criteria. A multiple-constituency approach that embraces the expectations of all organisational stakeholders is found to be the preferred assessment approach for the South African context. Empirical verification of the provisional theoretical model and the evaluation of 43 effectiveness criteria on a five-point scale, are accomplished by the elicitation of nine accredited experts' opinions from the academic, business and consultation fraternities. Identification of accredited experts and the elicitation of their knowledge are laborious tasks and require perseverance. Differences in average values of importance ratings by experts vary from 2,5 to 3,8 and are interpreted as indicative of strong individual assessment bias. The inconsistency of expert opinion is confirmed by an ANOVA-test which indicates that the differences among mean ratings of experts is practically significant at the five percent level of confidence. Median values of importance ratings are more representative than average values because of the inappropriateness of inclusion of marginal outlier values in the calculation of averages. An expert system shell is used to transpose the model into high-level computer code. Fractional contributions of different components and individual criteria are used to construct an inference net that comprises weighted sets of goals, subgoals and base questions. The program, Effectiveness Consultant, comprises 2600 lines of code and employs a rule base of more than 264 rules. The program is classed as a domain intensive, strategic consultative system. Evaluation of the facilitative potential and applicability of the proto-type version of Effectiveness Consultant by the nine experts is favourable. The system is rated above 4 on a scale from 1 (poor) to excellent (5). Possible applications of the system are the sensitising of management to a wider range of organisational issues which fall outside the scope of their area of expertise; the facilitation of more objective and consistent organisational diagnoses; the benchmarking of effectiveness before and after interventions and the evaluation of the general organisational situation before subscribing to specialised or functionally-directed consultative solutions. en
