Lean Production

An approach to production that aims to use fewer resources, including space, materials, stocks, suppliers, labor, capital, and time.

Just-in-Time (JIT) Production

A production strategy where materials are delivered right when they are needed in the production process.

Advantages of JIT

Improved cash flow, reduced waste, released space, no stock holding costs, stronger supplier links.

Disadvantages of JIT

Higher ordering costs, reliance on suppliers, lost bulk buying advantages, struggles with demand changes, vulnerable to supply breaks.

Study Notes

  • Lean production, developed by Toyota, aims to minimize resource use in production.
  • Lean production reduces space usage, materials, stocks, suppliers, labor, capital, and time.
  • Lean production raises productivity.
  • Lean production reduces costs and lead times.
  • Lean production reduces the number of defective products.
  • Lean production improves reliability and speeds up product design.
  • Lean production reduces waste and improves productivity and quality through various practices.
  • Holding stock ties up money, making it unproductive; for instance, US$1 million in stock means that US$1 million is unusable.
  • Just-in-time (JIT) production helps businesses overcome holding stock.
  • JIT means that suppliers deliver resources directly to the production line at regular intervals, even multiple times a day.
  • JIT means goods are produced only when ordered, avoiding the need to hold finished goods stock.

Advantages of JIT

  • Improved cash flow.
  • No waste, out-of-date, or damaged stock.
  • Released space.
  • No stock holding costs.
  • Stronger links with suppliers.
  • Fewer suppliers.
