Interlibrary Loan Meets Six Sigma: The University of Arizona Library's Success Applying Process Improvement

Abstract

Abstract In 2004, the University of Arizona Library Document Delivery Team embarked on a strategic project to assess the service quality and cost of filling interlibrary loan journal article borrowing requests. The Document Delivery Team utilized a Six Sigma Define, Measure, Analyze, Improve, and Control process improvement method. Improvements that were implemented as a result of this study led to increased satisfaction, decreased turnaround time, and lower cost per delivered article. Customer satisfaction surveys were utilized to discover customer expectations and requirements and to evaluate the effect of improvements on the customer experience. Measurement of internal business processes and cost analysis tools were used to determine cost savings. KEYWORDS: Six Sigmainterlibrary loan
