Students should understand what a supply chain is and recognise the…

The idea

A supply chain is the connected network of organisations and activities that transform raw materials into goods and services delivered to customers. It typically includes raw material suppliers, component makers, manufacturers, wholesalers, retailers and logistics providers. Managing it effectively means planning and controlling these links so the right quantity and quality arrive at the right time without excessive cost. Benefits include lower stock-holding costs, fewer delays, better cash flow, consistent quality and happier customers.

For example: A clothing retailer that shares sales data with its manufacturer can reorder popular lines quickly and discount slow sellers before they tie up cash.

What earns the marks

• Defines a supply chain as the network of organisations and activities linking raw materials to the final customer.
• Identifies typical links such as suppliers, manufacturers, wholesalers, retailers and logistics providers.
• Explains that effective management coordinates these links to match supply with demand in terms of time, quantity and quality.
• Recognises cost benefits including reduced stock holding, less waste and improved cash flow.
• Recognises operational and commercial benefits including fewer delays, consistent quality and higher customer satisfaction.
• Explains that a problem in one link, such as a delayed delivery, can disrupt later stages and damage the customer experience.
• Applies understanding to a given business, judging which benefits matter most for that context.

Common mistakes and how to put them right

• Describing only one link, such as the manufacturer, instead of the whole network.

  Put it right: Trace the chain from raw material to customer.

• Listing benefits without linking them to a cause.

  Put it right: Explain how coordination produces each benefit.

• Assuming all chains are identical.

  Put it right: The number and type of links vary by product and industry.

Exam tips

• Sketch the chain for the business in the question before writing, then refer to named links in your answer.
• Use connectives such as 'therefore' and 'which leads to' so each benefit is developed rather than listed.
• When asked to recognise benefits, give a range across cost, operations and customers to show breadth.
