Key DefinitionsValue – A capability provided to a customer at the right time at

an appropriate price as defined in each case by the customer.

Product ( or service) features, cost, performance and availability are dimensions of value.

Waste – Any activity that consumes resources but creates no value (waste).

Page 4: Lean Manufacturing A Presentation With Success Stories!!!

What Is Lean Manufacturing?

Lean manufacturing can be defined as “A systematic approach to identifying and eliminating waste (non-value-added activities) through continuous improvement by flowing the product at the pull of the customer in pursuit of perfection.”

Page 5: Lean Manufacturing A Presentation With Success Stories!!!

Over-view of Lean ProductionFocuses on eliminating wastes in

process Is not about eliminating people Is about expanding capacity by reducing

costs and cycle time Is about understanding what is important

to customer

Page 6: Lean Manufacturing A Presentation With Success Stories!!!

Lean = Eliminating Waste

D - DefectsO - OverproductionW - WaitingN - Non (under) utilized peopleT - Transportation I - InventoryM - MotionE - Extra (unnecessary) processing

(Typically 90-95% of Total Lead Time Is Non-Value Added!)

Page 7: Lean Manufacturing A Presentation With Success Stories!!!

Lean Is Not Restricted to Shop-floorLean is not a “point” solution but a

continuos improvement processLean practices & principles are not just

“shop floor” improvements Lean can be deployed in Marketing,

Finance, Design, Procurement and other Administrative areas

Best Companies are migrating lean “beyond shop floor”

Lean Manufacturing: A Brief History FORD

One of the most noteworthy accomplishments in maintaining low price of Ford Products was gradual shortening of their production cycle

“The longer an article is in the process of manufacture and the more it is moved about, the greater is its ultimate cost” – Henry Ford, 1926

Henry Ford identified 5 of the 7 Lean Wastes in the 1920’s

Page 9: Lean Manufacturing A Presentation With Success Stories!!!

Lean Manufacturing: A Brief HistoryTOYOTA

Manufacturer of Trucks and Small Automobiles in the post WW-II Japan

A need declared by Toyota’s President for a new production method that would help to eliminate wastes and catch up with foreign competitors

Chief Engineer studied Henry Ford’s writings and visited Ford plants extensively in the 1950’s

Page 10: Lean Manufacturing A Presentation With Success Stories!!!

Lean Manufacturing: A Brief HistoryTOYOTA

This led to “Toyota Production System (TPS)” which became popular in the 1970’s

The concept introduced by the Japanese was first applied by the factories in America

Later came to be known as

“Lean Manufacturing” Lean Production Strategies were adopted by

most industries around the world in the 1990’s and beyond

Page 11: Lean Manufacturing A Presentation With Success Stories!!!

Lean Enterprise - Definition

Extends lean principles to all business functions including manufacturing, finance, design, planning, human resource and supply chain

Page 18: Lean Manufacturing A Presentation With Success Stories!!!

Lean Vs. Traditional Half the hours of engineering effort Half the product development time Half the investment in machinery,tools and

equipment Half the human efforts in factory Half the defects in output Half the factory space for the same output A tenth or less of in-process inventories

Page 21: Lean Manufacturing A Presentation With Success Stories!!!

Value Stream Mapping

The initial step which must be taken for an organisation to adopt lean strategies

A method of visually mapping the flow of materials and information from the time products come in the back door as raw material, through all manufacturing process steps, and off the loading dock as finished products

Page 22: Lean Manufacturing A Presentation With Success Stories!!!

Value Stream MappingCan be a communication tool, a business

planning tool, and a tool to manage an Organisation’s change process

Visualises the current state of the process activities and guides towards the future desired state

Goal is to identify and eliminate waste (any non-value addition) in the process

Page 23: Lean Manufacturing A Presentation With Success Stories!!!

Benefits of Value Stream Mapping

Helps visualize the production process at the plant level not just the single process level

Helps you see more than waste it helps you see the sources of waste in your value stream

Shows the linkage between the information flow and the material flow

Page 24: Lean Manufacturing A Presentation With Success Stories!!!

Benefits of Value Stream Mapping

Makes decisions about the flow apparent, so you can discuss them

Forms the basis of an implementation planTies together lean concepts and

techniques to enable improvements that show up in your organization's bottom line

Page 25: Lean Manufacturing A Presentation With Success Stories!!!

Value of Time

Henry Ford, 1922, My Life and Work: "If a device would save in time just 10 per cent. or increase results 10 per cent., then its absence is always a 10 per cent tax.

…Save ten steps a day for each of twelve thousand employees and you will have saved fifty miles of wasted motion and misspent energy."

Page 26: Lean Manufacturing A Presentation With Success Stories!!!

Ford on Supplier Development "The man finally consented to try to manufacture

at exactly one half his former price. Then, for the first time in his life, he began to learn how to do business. …he found he could make cost reductions here, there, and everywhere, and the upshot of it was that he made more money out of the low price than he had ever made out of the high price, and his workmen have received a higher wage" (Henry Ford, 1926, Today and Tomorrow).

The supplier had wanted $152 per body. Ford built a model for $50 in labor and materials. The supplier then agreed to accept $72 per body.

Page 27: Lean Manufacturing A Presentation With Success Stories!!!

Waste To ProfitHenry Ford: A wood distillation plant turned scrap wood into methyl

alcohol, charcoal, tar, and fuel gas $12000/day could pay 2000 workers @$6/day (Ford's

relatively high minimum wage) in 1926 Charcoal briquettes from sawmill chips (Kingsford

charcoal) Blast furnace slag cement and paving material A paper plant converted waste paper into binder board

and cardboard Fumes from a coating operation were recovered by

adsorption in charcoal and reused

Keep Your Eye on the Doughnut's Hole

• Doughnut = the product

• Hole = whatever is thrown away

Example: metal sheet with six stamped holes (product)

Workers ask, "What was in those holes?"

Most people saw scrap for remelting and reuse. Ford's workers saw radiator caps. Pressing two disks made a very strong radiator cap.

Page 63: Lean Manufacturing A Presentation With Success Stories!!!

Problem Faced by the Company

Product demand outpaced its production capacity

Considered moving to a larger facility to allow for expansion

Page 64: Lean Manufacturing A Presentation With Success Stories!!!

Solution

General Manager decided to apply lean concepts

Realized his company did not need to move

Could instead improve its process flow

Page 65: Lean Manufacturing A Presentation With Success Stories!!!

ResultsDecreased work in process by 60 percent Reduced space requirements and product

damageStreamlined production processSimplified order entry Improved customer service and flexibility

to manufacture products as per order Avoided expense of moving to larger

facility, while expanding production

Philosophy

Page 70: Lean Manufacturing A Presentation With Success Stories!!!

Lean People Make a Lean Enterprise

An enterprise is a collection of people voluntarily banding together to produce a product or service

To have a lean enterprise, you have to have lean people

People have to get lean before the enterprise can get lean

Page 71: Lean Manufacturing A Presentation With Success Stories!!!

Lean People Have Something

Page 72: Lean Manufacturing A Presentation With Success Stories!!!

Skills

Pre-requisites to applying the knowledge And experience Understanding value Identifying and working in the value

stream Being able to adapt rapidly Leading from below Taking the initiative Innovating: changing things for the better Having a collaborative outlook

Page 73: Lean Manufacturing A Presentation With Success Stories!!!

Obstacles

Resistance to change – An emotional / Behavioural Response to real or imagined work change

Page 74: Lean Manufacturing A Presentation With Success Stories!!!

Main Reasons For Resistance To Change

Culture LimitationsKnowledge LimitationsManagement Limitations

Page 75: Lean Manufacturing A Presentation With Success Stories!!!

Culture LimitationAn individual’s misconception about

changePoor Communication Fear of failureClimate of mistrustTime Pressure

Page 76: Lean Manufacturing A Presentation With Success Stories!!!

Winston Churchill On Change

“To improve is to change; To be perfect is to change often”

Most Companies have “Continuos Improvement” in their Quality Policy but still resist Change

Page 79: Lean Manufacturing A Presentation With Success Stories!!!

Remember… Improvement Requires ChangeChange Requires ExperimentingNo Cookie-Cutter approach to ChangeNo one gets it right the first time, every

time!A Change-friendly culture will use “failure”

as an opportunity to learn and share

Page 80: Lean Manufacturing A Presentation With Success Stories!!!

Become Lean & Attain Innumerable Benefits

Improved customer service

Reduced inventory costs

Increased quality Reduced scrap Improved cash flow Increased

productivity

Decreased down time

Increased flexibility Reduced lead times Growth from within

the organization Better utilization of
