4A/B Manufacturing processes and systems

Question 1

What is JIT (just in time)?

Answer 1

• a STOCK-CONTROL system
• ensures fabric and components arrive at the factory just as they are needed to go on the production line
• aims to get products to shops as soon as possible and as they are needed

Question 2

Features (JIT)

Answer 2

• gives information about: the materials/components needed and at what stage of prod. they are needed
• whole process is controlled electronically using barcodes (read by scanners at each stage and information is stored on a central computer system)
• monitors outputs
• little stock is kept in warehouses
• regular deliveries from supplier
• materials/components arrive and are used almost immediately on the production line
• stock is bought in quantities

Question 3

Advantages (JIT)

Answer 3

• tracking product/stock means that up-to-date stock information can be seen
• saves on storage, warehouse and worker costs
• minimises waste/energy: the computerised system controls stock levels
• allows manufacturers to respond quickly when fashions/trends change: flexible working practice

Question 4

Disadvantages (JIT)

Answer 4

A delay in delivery could suspend the production line:
- increased costs (e.g. energy/wages)
- lost revenue (e.g. cancelled orders/ missed deadlines)
