The study assessed the relationship between procurement process compliance and procurement performance of public procuring entities in Rwanda; with a case of southern province Districts in Rwanda. The specific objectives were to assess the effects of procurement planning on the procurement performance of public procuring entities in Rwanda; to analyze the effects of procurement procedures compliance on the procurement performance of public procuring entities in Rwanda and to assess the effects of procurement transparency on procurement performance of public procuring entities in Rwanda. The target sample size comprised 94 persons selected purposively from the departments of procurement, finance, and customer services. The questionnaires and documentation research techniques were used during data collection. The findings revealed that procurement performance in public procuring entities was explained by a probability of 0.0124 for procurement planning; a probability of 0.007 for procurement procedures compliance; a probability of 0.0139 for procurement transparency and respectively expected 1.24% & 0.7% & 1.39% and of probabilities, which are less than 5%. Based on simple regression theories, each procurement process compliance factor presents a good fitness variability by each probability that is less than 5%. The R2 =0.9904 and Adjusted R2 =0.9901, show the goodness of fit of the estimated model. Up to 99.04% of long-run procurement performance appreciation is influenced by changes in procurement planning; procurement process compliance; procurement ethics as implemented by public procuring entities. Therefore, the researcher can conclude by saying that the research hypotheses including H1: Procurement planning has statistical effects towards procurement performance; H2: Procurement process compliance has statistical effects towards procurement performance; H3: Procurement transparency has statistical effects towards procurement performance” all were tested, verified and then they are confirmed referring to the statistical (regression analysis) findings. This confirms that there is a significant relationship between procurement process compliance with their observed indicators (factors) and procurement performance in public procuring entities in Rwanda.
