The aim of this research assessed the impact of internal business factors and the external operating environment on the performance of business organisations. The external and internal resource factors were modelled as higher-order factors, and the impact of the moderating effect of the internal business factors on the relationship between external factors and the performance of business organizations was analysed. The survey questionnaire was sent to over 380 companies. 146 responses (38 percent) were received. The data was analysed using Smart PLS 3. The results indicated that external resources have a direct and positive impact on the performance of business organisations and that the internal organisational resource factors have a positive moderating effect on the relationship between the external business environment and the performance of business organisations in South Africa.
