Every organisation has to buy goods and services and this means that Supply Chain people work everywhere from global corporations to market stalls. For many organisations, their biggest cost is the goods and services bought from third parties. This includes all the costs of managing supply including purchasing, expediting, inventory management, delivery and receipt of goods and quality control. Supply chains within and across all other sectors are reliant on the effectiveness of the people who work within them. Apprentices can work as Supply Chain Officers making sure goods are ordered and delivery of them is tracked. Advanced Apprentices may work as Supply Chain Managers, ensuring suppliers are supplying or delivering goods correctly.
