  1. Efficiency & Learning Where does new knowledge come from?

  2. epistemology “The study or theory of the origin, nature and limits of knowledge”

  3. learning • Tabula Rasa- • Or • Innate Knowledge? • Does Efficiency increase by Analysis • Or • by Imitation?

  4. “Efficiency Experts:” Frank & Lillian Gilbreth

  5. Therbligs – 17 Elemental Motions • Search • Select • Grasp • Hold • Transport • Release • “Think” Insomniac Agnostic Dyslexic Stayed up all night wondering if there is a dog.

  6. Motion Study Principles • Eliminate • Combine/ Coordinate • Reduce Fatigue • Arrange workplace • Improve tools and equipment • “Find the ‘one best way’ to do a piece of work.” • Find the laziest worker and study his approach.

  7. Learning improves efficiency • By both • Analysis and • Imitation

  8. Frank Gilbreth • Invented Time & Motion Study • Typewriter design changes • Foot levers on garbage cans • Military rifle disassembly blindfolded • Surgery assistant procedures • Use of Movies for T & M study • Increased the rate of bricklaying three fold!

  9. Frank Gilbreth • With his wife Lillian • Had twelve children

  10. Improve efficiency • Study a task that is performed frequently • Identify repetitive or unnecessary motions • Eliminate • Combine • Improve

  11. Coffeepot setup • Component taskcumulative time • Get pot, funnel 10 seconds • Fill pot, pour 40 • Coffee open, place filter 104 • Three scoops (12 sec) 116 • Assemble,put away 129 • Approx 2 minutes total

  12. A Larger scoop would save: • 8 seconds • For 350 days • For 30 years • 84,000 Seconds • 0.75 Applied Factor • 60 sec./minute • 60 min./hour • 31 hours per lifetime • Two Days wasted! • Larger scoop 49 cents

  13. Alternative Process--wife • Component taskcumulative time • Start water in pot 4 seconds • Scoop 3, turn off water 25 • Pour water, assemble 41 • Put away coffee 53 • Less than one minute total • I save 444 hours in a lifetime ~ one month! • “One best way to do work”

  14. People who exercise regularly live Longer • WSJ--Life expectancy has two more years • 365 days per year • 16 hours per day • 11,680 hours of extra life • 3 workouts per week • 2 hours • 50 weeks • 40 years • 12,000 hours spent working out.

  15. Do everything you do for its own sake. • Yesterday is a bucket of ashes that won’t burn again • Tomorrow is a dream you may never see. • Life isn’t a destination, It’s a journey… • And every day -- as good or as bad as it might seem -- • is the best of all possible days. • Where does new knowledge come from? ...

  16. People create new knowledge: • Analysis AND synthesis • Discovery... • “Seeing what others have seen and thinking what no one has thought.” • Seeing the world from new directions and understanding a new dimension...
