Lean Manufacturing Is a way of life. It is a never ending process Its tools need to tailored to meet XYZ Companys needs. Not a one size fits all method.
Lean Manufacturing DefinedA 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 --The MEP Lean NetworkXYZ CompanyCUSTOMERSUPPLIERWASTEWASTEWASTEWASTE

The Principles of Lean Manufacturing Focus on Value - Your customer determines value. Eliminate Waste - Eliminate all forms of waste. Build only what customer Pulls Quality, Quality, Quality.Jim Womack
What is Waste?Anything that adds Cost to the product without adding ValueValue = ?Ask yourself IS MY CUSTOMER PAYING FOR THIS ?Yes Can I do it faster, better, safer ?No Why am I doing it ?!

7 Forms of WasteLEAN = ELIMINATING THE WASTESValue - AddValue - Add
Overproduction Producing faster than consumption
Defects Variations and complexity
Non-value added processing Lack of standard methods
Waiting Producing slower than consumption
Transportation Disconnected operations
Excess motion Lack of better processes
Excess inventory Long lead times, ..7 Forms of Waste
Bricklaying, through late Nineteenth CenturyThe brick weighs about five pounds (2.3 kg). How much is the worker actually raising and lowering every time he bends over for another brick?Source: Levinson Productivity Systems, P.C.http://www.ct-yankee.com/lean/usa.ppt
Bricklaying, after Frank GilbrethThe joke about the underachievers and the light bulb isn't so funny any more.Lesson: waste can, by long habit ("living with it," "working around it") become built into a job.Source: Levinson Productivity Systems, P.C.http://www.ct-yankee.com/lean/usa.ppt
