Just-in-Sequence

How does the optimal JIS process work?

Just-in-sequence (JIS) is an extension of the just-in-time principle. JIS describes a delivery and provisioning strategy in which materials or components not only arrive at the assembly line on time, but also in the exact sequence required.


JIS is particularly important in the automotive industry, where vehicles are customised. It enables the direct provision of specific components - such as seats, bumpers or fittings - in the vehicle assembly sequence. The aim here is to minimise stock levels and increase production efficiency.

The success of JIS depends on a high degree of integration between production planning, logistics and IT systems. Any deviation in the sequence can lead to interruptions or incorrect installations. Therefore, precise data flows, real-time communication and flexible control are essential.


The nemetris JIS solutions enable seamless sequence control by linking planning, material flow and production in real time and ensuring that the sequence specifications are precisely adhered to - a decisive advantage for car manufacturers who require maximum variant diversity and stable processes at the same time.

Principles and special features of JIS

  • Exact sequence: the components arrive in the order in which they are installed
  • High level of synchronisation: delivery is precisely coordinated with the production process
  • Reduced warehousing: Storage costs are reduced as less material has to be stored temporarily
  • High demands on the supply chain: Strong dependence on precise planning and reliable suppliers

Example of just-in-sequence in the automotive industry:

In a vehicle production facility, different door panels are required for different vehicle models. Instead of keeping all variants in stock, the supplier delivers the door panels in the exact order in which the vehicles are produced.
