Six Sigma was implemented in the library to improve processes and satisfy user needs. Key results included reducing the time to complete tasks, eliminating defects, and increasing user visits and book checkouts. The Six Sigma approach helped library staff work more efficiently, completing one project in 20 days with no errors compared to 30 days previously with 25% errors. This increased the quality of library services and the sigma level from 2 to 6, indicating a significant improvement in meeting user expectations.
