This presentation will demonstrate how the UNLV University Libraries Acquisitions team is using Lean principles to analyze and improve acquisitions processes for firm and approval print and electronic monographic workflows. Lean process improvement is a system of concepts and tools to help an organization provide high value and high quality to our users in an efficient manner. In this session, the presenters will provide a brief overview of lean principles and how this system can be adapted to a library setting. The presenters will then show working examples of Lean-specific tools, like a Value-Stream map, that helped improve the UNLV Libraries acquisitions process. The aim for this session is for attendees to learn some basic Lean principles and how they can utilize these tools at their own institution.
