This article examines the relationship between supplier collaborative arrangements, supplier generative influence, self-organization and bid rigging in Uganda’s Public Procurement. A sample of 120 Procurement and Disposal Entities (PDE’s) and 317 supplier companies were selected with an average response rate of 76%.  Data was analyzed using Statistical Package for Social Scientists (SPSS). Results showed a positive and significant relationship between supplier collaborative arrangements, supplier generative influence, self-organization and bid rigging. Similarly, results of the regression model revealed that supplier collaborative arrangements, supplier generative influence and self-organization are significant predictors of bid rigging in Ugandan Public Procurement.  We recommend that in order for PDE’s in Uganda to reduce bid rigging special consideration should be directed at managing and monitoring suppliers’ behavior from the time of bidding until the contact has been fully executed.
