118 JUST-IN-TIME PRODUCTION Just-in-Time (JIT) production is a manufacturing and management approach that aims to produce goods only when they are needed and in the exact quantities required by the customer. JIT focuses on reducing inventory levels and eliminating waste throughout the production process. Instead of storing large amounts of raw materials or finished products, companies using JIT rely on precise planning, accurate demand forecasting, and close coordination with suppliers. This approach helps organisations lower storage costs, reduce the risk of overproduction, and quickly identify problems in the production flow. Key principles and benefits of JIT The principles of just-in-time production include smooth workflow, reliable processes, and strong communication across the supply chain. Materials and components are delivered to the production line exactly when they are required, which encourages companies to improve process reliability and quality. Because there is little excess inventory to hide mistakes, problems such as equipment failure or defects become immediately visible and can be solved 4 dashboard: cruscotto lead times: tempi di consegna supply chain: catena di approvvigionamento 5 quickly. JIT also promotes flexibility, allowing organisations to adjust production levels in response to changes in demand. As a result, companies can reduce lead times, improve product quality, and increase efficiency. However, successful JIT implementation requires disciplined planning, well-trained employees, and reliable suppliers, since delays or disruptions can quickly affect production. Real-world applications A well-known example of just-intime production can be found in the automotive industry. Toyota, for instance, uses JIT to coordinate its assembly lines with suppliers. Instead of keeping large warehouses full of parts, Toyota receives components such as seats, dashboards, and engines shortly before they are needed on the production line. If customer demand changes toward a different car model, production can be adjusted without leaving large amounts of unused inventory. This system reduces costs and increases efficiency, supporting high quality standards. Besides automotive manufacturing, JIT is also used in industries such as electronics and healthcare.
