Designing and implementing performance measurement systems in public contracts is not an easy task. Little guidance has been available on which specific measures work better in producing certain managerial benefits. The objective of this study is to evaluate the effect of different performance measurement practices on accountability effectiveness in government contracts. The findings suggest that the overall scope of performance measurement has a positive impact on the government's ability to effectively manage contracts. More specifically, measuring costs, client impact, service timeliness and disruptions, as well as specifying the detailed processes for service delivery are associated with higher accountability effectiveness.On the other hand, evaluating quality, client satisfaction, and using informal monitoring techniques has a negative impact on perceived accountability effectiveness. The results of this study provide motivation for the contract managers to optimize performance monitoring and reduce transaction costs by relying on the measures that are more likely to improve contract implementation.
