  7. History of the Plant • Ground breaking, May 1986 • First Car, May 1988 • Fujio Cho named the second president, Dec 1988 • 1 millionth Camry, Oct 1993 • 2 millionth Camry, Apr 1997 • Camry #1 selling car in the US in 97, 98, 99, 00 • Gary Convis named fifth president, Apr 2001 • Camry #1 selling car in the US in 02, 03, 04, 05 • Sixth generation Camry starts, Feb 2006

  8. Overview of the Production Process • ???? manufacturing, ???? • ????, used for panels, bumpers, connections, protections • ????, shaping the steel coils into body parts • Uses ???? dies (analogous to cookie cutters) • ???? of the body • ???? • ???? • Trim • Heater, A/C, Wiring • Bumpers, Headliners • Chassis, underbody work, engine marriage • Final line, air bags, instrument panels, seats • Final test, ????

  9. What is Doug Friesen’s problem?

  10. Doug Friesen’s problem A ???? run ratio of ??%: Number assembled actually / Number could be assembled • Line is stopped due to defectives by pulling an andon cord • Too often or too rare? • ????, defective car-seat combinations sent downstream • Defectives are due to ???? rotation, product ????, ???? ????/???? design • A substantial number of cars off-line with ???? seats or ???? seats. • Some cars wait ???? days for seats in the ???? area although ???? commits to send seats in a single shift. • Is the reordering of Ex.9 form readable? • Cars served FIFO? • What is the problem with the seats?

  11. What are the Seat Problems?

  12. Seat Problems • ???? • ???? • ???? • ???? More problems with the front or back seat?

  13. A Test of Japanese • Andon • Ikko-nagashi • Heijunka • Jidoka • Kaizen • Kanban • Muda • Poka-yoke • Takotei-mochi • Tsukurikomi What is violated at TMM?

  14. A Test of Japanese • Ikko-nagashi: Lot size of one • Heijunka: Production smoothing to end up with a level plan • Jidoka: Do not pass the defects to downstream • Takotei-mochi: Worker flexibility • Tsukurikomi: Built-in quality inspection

  15. 1. Line Stoppage Setting of the stage: A worker pulls the andon cord, music starts, team leader comes. TL: - What is the problem? W: - …………. TL: Decides how long the line should stop: 1 Cycle=?? seconds or more. If the problem is severe, TL calls the group leader.

  16. Continue to violate Jidoka? • Costs of line stoppage • Stopping for 1 cycle of 57 seconds • Loss of revenue by one car • Loss of profit • Overtime can be used to recover

  17. Continue to violate Jidoka? • Costs of line • Stopping for 1 cycle of ?? seconds • Loss of revenue by one car, $??,??? • Deduct costs of ??% • Loss of profit of $?,??? • Overtime can be used to recover • Cost of ?? seconds of overtime ??*??*??/????=$?.???/worker • How many workers stop and do overtime? • 1 team, 1 group, assembly line, paint line, …, entire plant? • Depends on the ????? inventory between work centers and the length of the stoppage. • Ikko-nagashi couples work centers: Stopping one is stopping all.

  18. 2. Crowding in the overflow area • Can you read the reorder form in Exhibit 9? • Computerize the information flow between TMM and ???? ? • What is the benefit of dedicating an ???? area specific to seat problems? • Dealing with mistakes efficiently vs. Eliminating mistakes

  19. 3. Assembly area • Job rotation, a problem source or a fix? • Is Takotei-mochi possible without rotation? • Hook, now made of ???? as opposed to ???? • Personal experience: ???? interior front door handles in my 94 Corolla • $50,000 to improve the hook design • Build a seat safety inventory to reduce mismatches?

  20. 3. Assembly area • Job rotation, a problem source or a fix? • Empowering the ????, ???? work force • Boredom is a source of errors, Reasonable ???? improve productivity • Hook, now made of ???? as opposed to ???? • $50,000 to improve the hook design • Distribute the cost to cars • (1 broken hook per shift)*(2 shifts per day)*(1000 days for this Camry generation) • Cost per car is $??, reasonable? • What if the hook problem continues after the redesign? • Investigate/respond to hook design change • Why does not Japanese plant experience the same problem? • Does TPS work better in Japan? Does TPS work only in Japanese culture? • Build a seat safety inventory to reduce mismatches

  21. 4. Supplier • Seat quality coming down • At least for the new models • Addition of Camry Wagon and more types of seats • Who is responsible for the seat defects • The supplier? • The transporter? • The TMM receiving? • Sharing the responsibility to find the root cause of the seat defects

  22. 5. Seat Mismatches: RFID as a potential fix • See Exhibit 6 for the layout • ???? comes from main line • ???? comes from a feeder line • Both ???? and ???? are RFID tagged • When the tags do not match, the workers are alerted • This eliminates “some” errors • Implemented in conjunction with a seat supplier according to ChainLink Research (www.chainlinkresearch.com) webinar on January 10, 2007.

  23. How much of TPS is culture?How much of it is science?

  24. Toyota is worried of its culture being diluted with fast overseas growth “… the hardest thing for Toyota’s new American employees to accept: those colored bar [performance] charts against a white bulletin board, in plain view for allto see.” Latondra Newton, Toyota Employee in Erlanger, KY New York Times Business Feb 15, 2007. Aspiring Toyota factory leaders attend Toyota Technical Skills Academy (high school) in Toyota City, Japan. They study mechanical drawing/design . A separate institution, Toyota Institute, prepares executives for Toyota Way. The institute sends off its executives to offices around the world as missionaries.

  26. Railway Tracks To Oakland Harbor To Fremont To San Jose

  27. History/Products • Late 70’s oil crisis • GM closes Fremont, CA plant firing 6000 in 1982 • Toyota approaches GM to set up Toyota production system at a GM plant, United Auto Workers accepts the deal • GM and Toyota put together $400M in 1984. • GM is the landlord, it owns the infrastructure • Toyota is the tenant • Nummi = New United Motor Manufacturing, Inc is born in 1984 as the unique example of a Toyota – GM joint venture • Products: Toyota Corolla, Tacoma Trucks, Pontiac Vibe (Toyota bottom, GM top) and Toyota Voltz (Toyota bottom, GM top, sold in Japan) , GM Prism until 13/12/01

  28. Workers • Nummi has about 4500 unionized workers • Workers are under two types: • Production, high school graduates • Maintenance • Workers work in teams of 4-6 • Workers in a team rotate the tasks every 1-3 hours • Team leader is responsible for the rotation. • Team leader withdraws parts from the inventory (every 1-2 hours) and provides the tools as necessary • Workers make $17 per hour

  29. Capacity • Nummi has a cycle time of • 60 seconds for Corolla, 1 body • 82 seconds for Tacoma, 3 bodies • only cabin is produced at Nummi, the bottom and the back are bought from suppliers • Nummi works in two shifts • I: 6:00-14:30, II: 16:30-1:00 • Each shift has 1 hour lunch/dinner break • Starting the first shift at 6:00 workers avoid heavy morning traffic • Two hours between shifts I and II is to allow for overtime after the first shift when necessary

  30. Work Flow • Stamping: Forming metal (side, back, front) panels with presses • Body & Weld: Putting panels together • Paint: Paint inspection is the current bottleneck • Primer body paint applied by robots (chemically hazardous task) • Door jambs painted manually • Plastics: Making bumpers, inside panels • Assembly: Putting in tires, engine, seats, bumpers, harnessing. Cars , trucks on 2 km , 0.8 km conveyors • Cars contain Building manifest = BOM = Ingredients list at every step of these operations

  31. Just in time • Kaizen: continuous improvement • Kanban: replenishment every 1-2 hours • Jidoka: Assure 100% quality. Otherwise pull the Andon chord • 1000 times per shift • 9% of line stops are longer than 30 seconds • Line stops longer than an hour once every month • Muda: Waste to be eliminated • Genchi Genbutsu: Go to the source to learn and to solve the problems • This Japanese terminology is all over the boards in the plant

  32. Creative Tool / Work Place Design • Die change at the stamping in 3 hours • Tilted storage bins for ease of access • Collapsing storage boxes when empty • To reduce the empty box storage requirements in trucks returning to suppliers, say in Indiana • These boxes save about $10M annually • The worker who suggested the boxes earned several thousand points. 1 point = $1. • More info www.nummi.com
