This research explores the relationship between the organisational culture and financial performance of a South African investment bank by means of quantitative research. The Denison Organizational Culture Survey was used to measure the organisational culture of the investment bank and was administered to a sample of 327 employees. Income statement ratio analysis was selected as a means to assess the financial performance. The results indicate that very few of the financial measures selected could be shown to be correlated with the organisational cultural traits or subscales. Correlations between the cultural dimensions of team orientation, agreement, customer focus and vision were found with certain financial measures. Although these correlations were above the 0.50 level, the levels of significance were not sufficient in all cases to draw conclusions with confidence. The only cultural trait that was found to be correlated with financial measures was the consistency trait. / Industrial and Organisational Psychology / M.Com.
