training costs increased to become specialist staff
decentralised storage is…
storing inventory in many locations e.g. smaller warehouses of storage rooms

The product is standardised which means quality is consistent
Reduces chance of human error which decreases wastage
Wage costs are reduced as less staff are required
Machines can do jobs considered dangerous to humans which reduces accidents
