Workflow optimization is an important way to reduce costs and provide better services for patrons.  With inefficient workflows, things take longer and cost more to get done.  

There are many methodologies for optimizing workflows such as Lean based on the Toyota Production System, and Six Sigma.  Lean methodologies focus on eliminating waste and improving quality.  Six Sigma focuses on the "quality of process outputs" and removing defects. And some practicitioners have been trained in a combination of both methodologies called Lean Six Sigma. Lori Ayre of The Galecia Group is a Green Belt in Lean Six Sigma and DFSS (Design for Six Sigma).  All of these methodologies can be applied to the library environment with excellent results. 

Areas that often yield the most dramatic benefits from workflow optimization are delivery systems, back office operations (technical services, processing, cataloging, and ILL) as well as materials handling functions (bookdrop check-in, holds pulling, sorting, etc.)
