This study examined the relationship between supply chain management practices and operational performance of firms in the Cape Coast Metropolitan area. Using simple random and convenience sampling techniques to select a sample of 100 respondents, the study administered questionnaire for data gathering, and a response rate of 75% was obtained. The study was built on descriptive survey design, based on quantitative strategy. Field data collected was analysed using descriptive and inferential statistics, applying mean scores, standard deviations and correlation estimates. The models developed were tested using multivariate linear and hierarchical regressions. The ordinary least squares estimation procedure was applied for generating and reporting the results. The findings show a positive significant relationship between all dimensions of supply chain management practices (top management support, customer focus and supplier management) and operational performance. Top management support emerged as the dimension with the strongest effect on operational performance. Further, the study found that customer focus management and supplier management practices have positive significant relationship with firms’ business process controls and improvements, and that process control and improvement fully mediates the relationship between supplier management practices and operational performance. The study recommends that managers should continue to provide supportive directions, guidance and resources for the design and implementation of strategic supply chain management activities.
