Mass Production - Characteristics
1. Quantity not quality2. Poorly skilled workers3. Huge Factories4. Non- flexible workers5. Lots of storage space required6. Focus on worker and self not company

Mass Production
Mass Production Developed by Henry Ford in 1913.
Definition- Production of items in large quantities by groups of workers in factories
◦Expensive and lots of machinery◦1880 electrification of factories

Mass Production
Developed in USA , by Ford Motor Co.Only supervisor can stop the assembly
lineMost important quality – amount of items
produced
Poorly skilled workers- only trained in one job

Mass Production
Quality Control depends on accuracy of the machine set up by workers
Jig – holds and guides material as its being processed
Fixture – keeps items being processed in proper position

Mass Production
Mass Production uses high volume shipping methods- 3 months of parts in warehouse
Quick fact- Model T was produced every 10 seconds

Lean Production
Produced and developed by JapaneseDefinition- System which focues on
producing a high number of items with exceptional quality and limited yet efficient workers.
Developed 1930-1940s

Lean Production Characteristics
Just in time Supplies
Quick Change over
Compressed Space
Highly skilled workers
Empowered workers
Flexible workers

Lean Production
Any worker can stop the line
Uses just in time shipping ◦No storage◦Less workers◦cheaper
Go-no-Go Gauge- used to check size / quality of produced product
Kan-ban◦Shipping idealogy◦1 item on line◦1 item ready for line◦1 item being shipped

Lean production- Kaizain
Japanese proverb: small incremental improvements toward a common goal each day
This was the Japanese workers philosophy each day!
Japanese put the company first
