Increasingly, organisations strive to shape their knowledge environment and organisational culture for improved performance and organisational success. Despite that, existing evidence recounts the individual role of organisational culture, knowledge management and intellectual capital towards organisational performance and success, a comprehensive explanation of the effect of multiple dimensions of these factors on organisational success remains unexplored. This paper adds to existing literature by proposing that an organisation’s knowledge environment combines its knowledge sharing practices (i.e. knowledge types, knowledge sharing approaches and knowledge sharing processes) and its intellectual capital. This paper presents a conceptual model on the relationship between organisational culture, knowledge environment and organisational success. The model proposes the role of organisational culture in shaping knowledge sharing practices, intellectual capital and organisational success. This research-in-progress concludes with directions for future research on the effect of organisational culture, knowledge sharing practices and intellectual capital on organisational success.
