SUMMARY
There remains a constant need for further empirical research on organisational performance in the public sector, in a bid to generate current and relevant solutions. Such an approach could be a panacea for performance-related problems that continue to affect public organisations in developing countries. The purpose of this study was to examine the relationship between organisational performance and three input factors; namely, innovation, inter-organisational systems and quality. A quantitative approach using the survey method was used in which a questionnaire was administered to 272 randomly selected managers and employees of a South African government department. Data were analysed using a combination of descriptive and non-parametric statistics. Spearmans rho was used to measure the strength of the relationships and regression analysis was used to measure the extent to which the input factors predicted organisational performance. Spearmans correlations showed strong positive relationships between organisational performance and all three factors while regression analysis also revealed that the three factors predicted organisational performance. The study is significant in that managers in public organisations can use the findings as a diagnostic tool in performance problems, with a view to enhance organisational performance among public sector organisations.
