Q

what is lean manufacturing

A

where you manufacture products just before they are required to help eliminate waste

17
Q

in what ways are waste eliminated by lean manufacturing

A

It eliminates waste from:
overproduction
waiting
transportation
inappropriate processing
excessive inventory
unnecessary motion
defects

18
Q

what is JIT production

A

creating items just before they are demanded

19
Q

what are the advantages of JIT

A

no:
surplus stock
components
finished parts

20
Q

What are the disadvantages of JIT

A

they require regular deliveries that bring what is needed before existing raw materials run out
they need suppliers to be local to reduce lead times and delivery costs
