  1. Continuous Process Improvement: The Lessons of History BADM 701 Dr. Ron Lembke

  2. Cotton Gin at Work

  3. Eli Whitney • Introduced interchangeable parts in large musket contract for U.S. Army • Interchangeable parts the true secret of Ford’s success • Made possible by advances in measurement and tool steel

  4. Tool Steel Advances

  5. Beginning of Standards • Before standardized parts, need Screws • 1860s Machine Tool industry: Silicon Valley of its day • All screws custom made by tool & die shops according to what they thought best • William Sellers: 1864 “On a Uniform System of Screw Threads”

  6. Sellers vs. Whitworth Sellers objectively better • Easier: simple angle vs. difficult; rounded top vs. straight • 3 cutters & 2 lathes vs. 1 cutter & 1 lathe

  7. Not Just What you Know • Machine tool makers didn’t want to be commoditized like gun makers • The standard people expect to win usually does. • Navy Board found it superior, asked Singer Sewing Machine, Baldwin Locomotive which would win (already adopted). • Pennsylvania RR adopted (Sellers on the Board) • British tanks & trucks couldn’t be repaired in WWII because Britain adopted Whitworth

  8. Frederick W. Taylor • Scientific Management • Searching for the “One Best Way” to do a process • Find ways to improve work environment and work processes • Quantify, measure & track everything: Time required to haul wheelbarrow:

  9. Factory Life Henry Noll “Schmidt” Taylor’s Factory

  10. Frank and Lillian Gilbreth • Systematically study a work environment and find the best way to achieve a particular task • With Taylor, pioneered “industrial engineering” -- time and motion studies • “Cheaper by the Dozen”

  11. Motion Capture • Lights illuminate key motion joints • For Computer Generation, convert to 3D

  12. Barry Zito

  13. Chronocyclegraph light-1914

  14. Bricklayer Hourly output up from 125 to 350

  15. Typesetter

  16. Drill Press

  17. The Entire Work Environment • Color coded slots • Groove for grabbing pencil

  18. ErgonomicsToday

  19. Ergonomics Then

  20. Continuous Process Improvement • Eli Whitney and Interchangeable Parts • William Sellers and the rise of standards • Frederick Winslow Taylor and Scientific Management • Frank & Lillian Gilbreth and time and motion study
