The objective of this study was to assess the Upstream Supply Chain Integration in EthiopianrnBrewery Sector by taking the case company, BGI Ethiopia Plc. To carry out this task anrnexplanatory type of research design was adhered. The target populations were upstream BGIrnEthiopia partners & Supply Chain staff, and their total number were 860( 851 suppliers and 9 BGIrnstaff) out of which a sample size of 274 ( 265 suppliers and 9 BGI staff) units has been determined.rnWhereas, a clean response of 235 questionnaires were effectively used for analysis that showsrnresponse rate of 85.8% .The major findings of the study indicates that the practice of upstreamrnsupply chain integration in the case company is very weak. Very few variables of the upstreamrnsupply chain integration considerations were practiced. These include the accuracy ofrninformation sharing (mean value of 2.76), operating with supply contract/commitment (meanrnvalue of 2.5), and informal & personal relationship (mean value of 2.9). The Pearson correlationrnanalysis result indicated that there were positive relationship between all of independentrnvariables and the dependent variable. Furthermore, the linear regression model revealed that outrnof the four predictors the two predictors organizational relationship linkage (b coefficient 0.63)rn& management commitment (b coefficient 0.48) has been founds as a predictor variables thatrnhave got high level of intensity to influence the response variable, upstream supply chainrnintegration. Finally, the researcher recommended that getting organizational legal groundrnthrough the inculcation of upstream supply chain integration in the sourcing policy andrnprocedure is the foundation work which should be accompanied with continuous learning, andrnsourcing reform.
