  1. Evaluating Methods of Change Nancy Kress Head, Bookstacks Department University of Chicago Library

  2. The ChallengeUsers expect books to be on the shelf at all times Bookstacks Mission: The Stacks Department serves library patrons through quick, accurate re-shelving of library materials.

  3. Methodologies for Change 2003 - present • Process mapping • 2003-2005 • Continuous process improvement • 2004-present • Lean Manufacturing • present

  4. What wasn’t solved? • Peak book returns • 4 quarterly due dates • Normal weekly book returns avg. 8,000 • Peak weekly returns avg. 35,000

  5. Best Practice Models • Other Libraries • Similar process organizations • U.S. Post Office • Library Bindery

  6. Heckman Plant Tour • View lean manufacturing process • Improve Bookstacks efficiencies at Regenstein

  7. What is “Lean Manufacturing?” • Lean manufacturing is aimed at elimination of waste • Organize processes to add value to the customer • Deliver goods “just-in-time” • Service organizations also using lean

  8. History of Lean • “The Machine That Changed the World” • Toyota auto manufacturing • “Value chain”

  9. Basic Lean Principles • Add nothing but value • Eliminate “muda” – waste • Do it right the first time • People doing the work add value • Team oriented • Deliver on demand • “Pull” instead of push

  10. Lean learned from Heckman • Key Principle #1: Pull… • …means work isn’t done until a downstream process requires it • Make only what the next process needs – when it needs it

  11. “Pull” becomes “Immediate Shelving” • The Process: • Only full shelves pulled to cart • One shelf = 30 minutes

  12. Lean learned from Heckman • Key Principle #2: Batching • Key to rapid delivery is small batch sizes

  13. “The Goal” by Eliyahu M. Goldratt & Jeff Cox • “This book is about progress. It’s about the creation and acceptance of improvements – change for the better.”

  14. More from “The Goal”… • What is the Bookstacks Department’s ONE goal? • Quick, accurate reshelving • All books on the shelf in correct order, ALL THE TIME

  15. Are we meeting the Goal?

  16. Our Challenge for Lean • Peak Book Returns • 4 Quarterly Due Dates • Normal weekly returns: 6,000 • Peak returns: 35,000

  17. Brainstorming Session • Book knowledge can only go so far… • Best way to learn is by DOING • Begin where the greatest need exists

  18. Creating “level pull” • “Level pull” is basically a replenishment model • Replenish Bookstacks shelves • Create a “level” daily schedule of work • Use inventory to buffer against large swings in work

  19. Keys to level pull • Create inventory • “supermarket” • Organize how inventory is stored • Consolidate similar types

  20. Optimize the Bottlenecks • Reduce batch sizes • Eliminate uneven amounts of work • Put the best people on the bottlenecks • They set the pace

  21. The Lean Solution

  22. Future Outcomes? • GOAL: measurable results • VALUE: high use books are on shelf

  23. Actual Outcomes

  24. Future Goals • Bionic Bookstacks • Better • Stronger • Faster

  25. Exercise: Identifying Waste • What activities add no value to library users?

  26. Waste Categories • Overproducing • Inventory • Waiting • Extra Processing • Correction • Excess Motion • Transportation • Underutilized People
