The main objective of the study was to examine the relationship between contract management and service delivery in the public sector in Uganda taking Kawolo Hospital as a case study. The study was guided by three research objectives which were to establish the relationship between; contract administration and service delivery, delivery management and service delivery and relationship management and service delivery. Questionnaires and interviews were used to collect data from a sample of 134 respondents of which ninety (90) returned their well filled questionnaires giving a response rate of 67.2%. The findings revealed that all the relationships were positive and significant, except relationship between contract administration and service delivery. The results shows that there was no significant relationship between contract administration and service delivery (r=0.158, p<0.136), there was a significant relationship between delivery management and service delivery (r=0.532, p<0.000); while relationship between relationship management and service delivery was also significant (r=0.354, p<0.001). However, none of the variables were highly inter-related. The researcher concludes that delivery management is more significant in contract management than the blend of relationship management and contract administration accounting for 28.3% variation in service delivery in Uganda Public sector.
