Supplier Distributor Customer Manufacturer Dealer Order Delivery Lead-time The Bullwhip Effect • Longer lead-time + more variation more whip Demand Information
To Tame the Bullwhip Effect: • Reduce order-to-delivery lead-time. • Deliver on-time confidence. • Increase visibility and accuracy of information on true daily demand, supply chain inventory and ETA. • Introduce frequent (daily) replenishment through the supply chain.
How Toyota Tamed the Bullwhip • Implement TPS/JIT Logistics throughout the supply chain to create an efficient, levelflow. Sell-one, Buy-one, Make-one Suppliers N.A. Parts Centers Region PDC Dealers 1 pc/day 1 pc/day 1 pc/day

Conclusion • Storage, information and planning warehouse efficiency • Culture for problem solvingkaizen • Taming the “Bullwhip Effect”level flow of product and information • “Systems thinking”Lean supply chain
Create Problem Solving Culture • Create binary business processes. • To standardize best practice. • To expose problems. • Coach problem solving at lowest possible level. • Use everyemployee’s full human potential. • “Kaizen mind”—change every 3 – 4 months.
Part Two The Toyota Way
The Toyota Way Wisdom from the Desk of, Chief Officer of Business Development & Purchasing Parts, Toyota Motor Corporation The Toyota Production System, AKA The “Thinking Production System” TPS as a winning strategy for developing g people in the global manufacturing environment.
Minoura’s Lessons from Ohno Early in his career, Minoura worked under Taiichi Ohno, recognized as the creator of the Toyota Production System. Ohno, through tireless trial and error, managed to put into practice a “pull” system that stopped the factory producing unnecessary items. But Minoura observes that it was only by developing this “loose collection of techniques” into a fully-fledged system, dubbed the Toyota Production System or TPS, that they were able to deploy this throughout the company. Taichi Ohno A Modern Toyota Assembly Line
Minoura’s Lessons from Ohno • A “pull” system ask workers to use their heads • “An environment where people have to think brings • with it wisdom, and this wisdom brings kaizen (CI)”. • In TPS, the T also stands for “Thinking” • “I don’t think he was interested in my answer at all/ • I think he was just putting me through some kind • Of training to get me to lean to think.” • To cut lead-time, cut out all the bits that don’t • add value
Minoura’s Lessons from Ohno • The line must stop if there is a problem. Andon Electric Light Board • Deal with defects only when they occur, • and the number of staff you need will drop.
Minoura’s Lessons from Ohno • Ask yourself “Why” five times. • “That way you’ll find the root cause, and if you get rid • of that it’ll” never happen again.” • “However, on-the-spot observation rather than deduction • Is the only correct way to answer a “Why?” question.” Improved die casting machine, developed by Toyota, is customized to reflect the shape of the finished product, cost 5)% less than its predecessor, and has on-third the production lead-timed
Minoura’s Lessons from Ohno • Train people to follow rules and standards • as if second nature • “Human beings are the ones who actually build quality into • a product..” Human Beings Build Quality Into a Product
Minoura’s Lessons from Ohno • Find where part is made cheaply and • use that price as a benchmark. “If we find that there’s a place in the world where they can produce this or that part for this or that price, we should use that price as a benchmark, and pour or efforts into finding a way to make even more cheaply locally.” Using Toyota’s V-Comm digital engineering technology, engineers in Japan and overseas work together to optimize production processes.
Minoura’s Lessons from Ohno • Develop people who can come up; with unique ideas. And here resides the other part of the Toyota DNA. the human behavior system ( The Toyota Way) which complements the process behavior system (The Toyota Production System) Both equally essential in lasting and continued success of Toyotl “
Part Three Ok – What’s Lean, Six Sigma, CI and EI got to do with SCOR ?
SCM and SCOR Model SCM – A Basic Definition and the SCOR Model Definition- Supply Chain Management is the design and management of seamless, value-added processes across organizational boundaries to meet the real needs of the end customer. The development an integration of people and technological resources are critical to successful supply chain integration. The SCOR Model – A most recognized and proven tool that provides unique structure that links business best practices, processes, metrics, and technology to form a unified structure to link and support communication among SC partners and to enhance the effectiveness of SCM and related SC improvement activities.

Part Four A System/Enterprise Aspect of Lean SCM From A Commercial Aircraft Perspective
With the 100th anniversary of manned flight in 2003 let’s take a look at the commercial A/C business • The commercial A/C business… • Aluminum primary structural material for over 60 years • Composites Technology lagging in the US • Commercial jet transports introduced 46 years ago • Mach 3 flight over 40 years ago • First Moon landings over 30 years ago • 747 introduced over 30 years ago; big twins 18 years ago • Space Shuttle in service over 23 years • Stealth aircraft operational over 16 years ago • US supersonic transport research effectively canceled • Sonic Cruiser was a nice dream • But .. The Dream liner is real (Boeing 787)
Lean in the 21st Century.. • Lean is the key to an economically vital, technically innovative Industries early in the 21st Century • Lean addresses the Industry’s fundamental, structural challenges • Lean is a logical extension of some of the Industry’s greatest achievements • Yet strategically valuable Lean still eludes many companies
Historical Development: From lean to mass to mess to... • Early days at Pratt Whitney (circa 1925) demonstrate Lean as natural way of organizing production • Flow manufacturing, cellular-like arrangements • Product-centric layout and organization • European production follows similar patterns • Takt time (concept and term) invented at Folke - Wolf in 1920s
Historical Development: From lean to mass to mess to... • Product performance is primary focus as Industry advances during 1920 & 30s. • Engineering specializes - silos emerge • Production follows specialization pattern - silos emerge as separate capabilities and facilities • As product oriented production fades, “management of complexity” becomes major cost, cycle-times stretch out
Historical Development: From lean to mass to mess to... • World War II drives industry expansion - Lean makes another appearance as enabler of massive, victorious output • Tightly integrated production lines enable heroic output • Takt time synchronization of production lines • Level scheduling, standard work are the norm • Assets are product-focused and fully utilized • WW II production creates huge Industry asset base at Government expense (much of which remains active today)
