According to Sollish and Semanik (2012), procurement refers to events handled by a company for proper management of the supply chain. Manufacturing organizations should readjust their procurement practices with the aim of enhancing efficiency and promoting environmental conservation. Interviews were conducted, data collected and analyzed and finally recommendations were made based on the results. This research focused on achieving efficiency and effectiveness within the procurement department so as to improve overall organizational performance. This study’s objective was to determine how organizational performance is affected by procurement practices. Questionnaires were used as a form of data collection. The study population for this research were the finance and procurement employees of National Water and Sewage Cooperation, Kampala. This research embraced a descriptive design, which depicts participants in an accurate way; it describes the people who take part in the study. The research findings revealed that 80% of the population sampled were of the opinion that joint improvement activities positively influenced the operations of the organization, 20% disagreed with this. 57% believed sharing of information intensively but selectively increased organizational performance, while 43% disagreed. The study recommends the building of robust relationships with key suppliers to guarantee unfailing supply and quality of inputs. Manufacturing companies must assess where their greatest investments are made and the benefit procurement can bring to each category. After significant investments are made in machinery, equipment and facilities, the next largest investment should be made in inventories. This is where the organization can produce savings through more efficient production, better utilization of floor space, better service and products to customers.
