Governments in both affluent and developing countries employ procurement strategies to decrease costs, resulting in large cash outflows that have a substantial influence on their economy. However, especially in the public sector, public procurement practices are usually disregarded in terms of their impact on an organization's success. As a result, utilizing Metropolitan, Municipal, and Distract Assemblies (MMDAs) in Ghana's Ashanti Region as case study institutions, it is unavoidable to investigate public sector procurement practices and their impact on organizational performance. The survey study design was used to map out the data collection process. A purposively sampled cohort of 113 people was used to administer the questionnaire. Using the Probit Regression Model, the study claims that procurement practices such as planning, sourcing, and contract management have a substantial positive link with organizational success. Given the interdependence of all dimensions of procurement practices, procurement practitioners are urged to give each factor proportionate attention to improve organizational performance.
