Overview of just-in-time management
The Just-in-Time method, symbolized by the acronym JIT and also known as “lean production,” revolutionizes traditional inventory management by synchronizing supply with actual demand. Companies using this system only replenish stock once provisional or fixed orders have been placed. When an order is confirmed, the company immediately orders the necessary raw materials, components, or goods required, with delivery occurring with limited or non-existent storage time.
Historical origins and modern applications
Originally, this method was developed in very small Japanese shops that lacked the physical space to store multiple products simultaneously, requiring several deliveries per day. Today, retail pharmacies exemplify JIT methodology perfectly, receiving daily deliveries from dispatchers to maintain minimal on-site inventory while ensuring product availability.
Key requirements for successful implementation
To work efficiently with customers and suppliers, just-in-time stock management requires strict compliance with essential rules:
- Draw up provisional needs in terms of goods or production
- Minimize transport fees and bulk breaking times by focusing on local sourcing
- Ensure absolute certainty in delivering unaltered goods on time
- Favor flexible delivery hours
- Maintain utmost proficiency in ordering processes and quantities
Operating systems
Just-in-time or lean production can be operated in two different ways:
Push or Kanban System: Used when production is based on provisional random sales and forecasted demand
Pull System: Implemented when production is based on effective, confirmed orders from customers
Benefits and strategic value
Though stock represents a main source of revenue, it also generates substantial fees. The JIT method addresses this by reducing costs across multiple areas. Reduced stock requires less warehouse space, handling, transport, disposal, and depreciation, while minimizing cash disbursements. The just-in-time method encourages greater flexibility regarding deliveries, enhanced responsiveness to market changes, and improved overall competitiveness in the logistics chain.
