Corporate culture is believed to be integral to organisational success and sustainability. This research study was conducted according to a humanistic, positive psychology and an open systems paradigm in order to examine the theoretical relationship between organisational culture and organisational commitment. The quantitative measuring instruments used for data collection were the Harrison and Stokes organisational culture questionnaire (OCQ) and Allen and Meyer’s organisational commitment scale (OCS). The empirical study involved respondents from a selected IT company in the KwaZulu-Natal region. This study revealed that there was no significant relationship between organisational culture and organisational commitment. However, there was a difference between the existing and preferred power culture as well as the existing and preferred role culture dimensions. The main recommendation for this study is that the selected IT company should set stretch targets with a focus on common vision, purpose and company values, with a strong emphasis on creating meaningful rewards for top performers at both individual and team level. / Industrial and Organisational Psychology / M.
