What does Just-in-Sequence mean?
The term Just in Sequence (JIS) describes a delivery method in procurement logistics. The JIS process is a further development of just-in-time (JIT) delivery. The delivery of necessary materials for production is delivered in quantity and type as well as in sequence at the exact time required for production.
In order to realize a smooth procurement according to Just in Sequence, to determine the demand and to minimize the effort in the supply chain, an electronic data interchange (EDI systems) and the communication between buyer and supplier is indispensable. A typical application area is the automotive industry. Automobile manufacturers operate this delivery method to perfection.
The delivery of the parts is both timely and in the correct sequence and position to the assembly line. There, the final assembly of the components to the existing construction takes place immediately.
Just-in-sequence production is oriented to the production cycle. This form of procurement logistics is only made possible by excellent transportation planning. The task of transport planning is to keep inventory and transport costs as low as possible. Elementary features here are the determination of the optimum quantity and calculation of the correct time of delivery so as not to interrupt continuous production.
Advantages of procurement logistics - Just in Sequence
- no inventory costs at the recipient
- no stock at the consignee
- Delivery of the modules to the assembly line
- Minimum space requirement at the assembly
- Production-synchronous variants for final assembly
Disadvantages of procurement logistics - Just in Sequence
- High communication effort between buyer and supplier
- High dependence on the supplier
- in the event of complications, risk of production stoppage
When implemented consistently, the advantages for companies outweigh the disadvantages. The process minimizes capital commitment, warehousing is almost completely eliminated and the goods are delivered at the right time to supply the vehicles in the pearl necklace with the right modules. No notification is made in the process.
