Abstract: Culture may have a big influence on the performance of all organizations worldwide. This is a practice that cannot just be assumed as it has both positive and negative effects as far as performance is concerned. It is more serious when it comes to non-Governmental organizations, since in most cases they involve international Governments. The main focus of the study was the non-governmental organizations in Kenya with a specific focus on World Vision Kenya. The specific objectives of the study were to establish the link between competitive culture and performance in Non-Governmental Organizations, to explore the effect of entrepreneurial culture on performance in Non-Governmental Organizations, to assess the level of bureaucratic culture and its influence on overall performance in Non-Governmental Organizations, to examine the influence of consensual culture on performance in Non-Governmental Organizations, and finally to identify the preferred cultural integrations in Non-Governmental Organizations in Kenya.
