It is a comprehensive set of techniques that are used to identification and stady
elimination of wastes,improvement of quality,reduction of production and cost
What is lean
Elimination of waste
Improve of quality
Identification
Reduction cost

TPS Definitions of Waste(7 types)
1. Overproduction2. Waiting, including time in
queue3. Transportation (between
workstations, or between supplier and customer)
4. Non-value-adding activities5. Inventory6. Waste motion7. Cost of poor quality: scrap,
rework, and inspection
“Anything that adds Cost to the product without adding Value”

+ Human
intelligence
A level of human intelligence is transferred into automated machinery
Practice of stopping a manual line or process automatically
Frees the operator from watching the machine

FOOT-PRINT
avoids employees wasting time looking for things
The workplace becomes clean and better organized.
Operation on the shop floor and office become easier and safer
Use colours as a guideline :
Light Blue - Raw parts/material
Black - Finished good/parts
Red - Non-conforming/KIV parts/material
White - Other than parts/material
Yellow – Border of work area
