What is batch production?
Specific number made
How many products are in a batch?
Large products e.g. planes – a few
Small products e.g. baked beans – hundreds of thousands
Advantages of batch production?
Product can be changed to suit market demands; machinery can also be changed to suit market demands

Who introduced JIT?

Small changes can easily be made to production
What are the issues with JIT?
Precise planning and timing is needed
What are the advantages of standardised components?
Company does not need to produce them
More time for designing their product
No space needed to manufacture them
Saves cost as no machines or staff needed
What are the disadvantages of standardized components?
Quality cannot be guaranteed
Dependent on delivery
