Kaizen (part of lean production) =

• continuous improvement

Just-in-time aims for

• maximum buffer (spare) stock

• zero buffer (spare) stock

• very large infrequent deliveries from supplier

Kaizen ideas come from :

• customers

• workers

• top managers

• local community

Compared to Mass production, Lean production has :

• longer production runs (making the same item before switching)

• shorter production runs (making the same item before switching)

• same length of production runs (making the same item before switching)

Just-in-time may fail due to :

• flexible, motivated workers

• accurate predictions of demand

• unreliable suppliers

Quality assurance =

• inspection at the end of the production process

• checking quality at each stage of the production process

A key indicator of quality :

• uncertain reliability

• numerous defects

• repeat purchases (loyalty)

• very low price
