This research study was aimed at identifying the role of organisational culture in the adoption of business intelligence systems in Ugandan public institutions. A structured survey questionnaire based on the Organizational Culture Assessment Instrument (OCAI) by Cameroon and Quinn, and the Technology Acceptance Model (TAM) proposed by Davis (1989) and Venkatesh et al. (2003) was utilized to assess the dominant organisational culture and Business Intelligence Systems Adoption respectively. 106 questionnaires were completed by middle to top managers in four (4) Ugandan public organisation. The research study found that Ugandan public institutions predominantly exhibit hierarchy culture and in some organisations market culture. However, statistical tests to answer the research question revealed that organisational culture did not significantly influence BIS adoption. In addition, there was no difference between the culture types exhibited in relation to BIS adoption. Therefore, future studies may explore other factors that influence BIS adoption aside from organisational culture.
