These products are identical and produced in small batches, daily, weekly, monthly or when needed. They can range in cost priced. Production normally runs from between 2 - 10k.
What are the connotations of mass production?
These products are produced in very high volumes, 10k +. They are normally products that are in high demand and can range in expense, cars are a good example.
What are the connotations of continuous production?
These items are normally very cheap to but make and could be considered ‘throwaway’. These factories are often found in developing countries where land for factories and equipment are cheaper.
What are the connotations of just in time production(JIT)?
This scale of production relies on the product been manufactured to a time schedule. This allows raw materials to be delivered at an exact time for production and then manufactured and are shipped straight to distribution /retailers. Apple INC uses JIT production.
