Everything from a smartphone to a packet of biscuits starts as raw materials and ends on a shelf or doorstep. The network of businesses that moves a product along this journey is called a supply chain.

The main stages

  • Sourcing: raw materials and components are obtained from suppliers.
  • Manufacturing: materials are processed and assembled into goods.
  • Warehousing: finished goods are stored and tracked.
  • Distribution: products travel by road, rail, sea or air.
  • Retail or delivery: goods reach shops or customers.

Why it is fragile

Because stages depend on one another, a delay at one point can ripple across the chain. Weather, strikes, shortages of materials, transport bottlenecks or policy changes can all cause disruptions.

How companies build resilience

Businesses may use more than one supplier, hold safety stock, improve forecasting and track goods with software. Close communication with suppliers helps problems surface earlier.

What it means for you

Supply chain problems can influence prices, availability and delivery times. They also show why local manufacturing and diverse sourcing are often discussed in business news.

Takeaway

The next time you buy something, remember the long chain of people and processes behind it.
