Just-in-Sequence delivery (JIS) is a supply strategy in which components are not only delivered at the right time, but in exactly the sequence of the production line. A sequence error leads directly to a standstill on the assembly line.
Key facts
- Just-in-Sequence extends Just-in-Time by adding the dimension of correct sequence: parts must not only arrive on time, but in the exact order in which they are to be installed.
- Sequence errors can immediately trigger a production stoppage, which is why the error tolerance in the JIS concept is extremely low.
- Transmitting the production sequence via EDI or API is a critical process step that demands high data quality and low latency.
- Buffers are only permissible to a very limited extent in the JIS concept, as any buffer can jeopardize the sequence.
- JIS requires stable planning, unique labeling of load carriers, and functioning escalation processes in the event of deviations.
What is Just-in-Sequence delivery?
Just-in-Sequence (JIS) is an extension of the Just-in-Time principle. While Just-in-Time ensures that material arrives at the right place at the right time, JIS adds a further dimension: the correct sequence. Components are provided so that they arrive at the assembly line in exactly the order in which the products being manufactured pass through it. Typical areas of application include automotive manufacturing, mechanical engineering, and other industries with high-variant series production, where each vehicle or product carries an individual configuration.
How does JIS work in practice?
The process begins with the transmission of the production sequence to the supplier or the upstream sequencing operation. This sequence information is frequently transmitted via EDI or API from the ERP or production control system. The supplier or a service provider then assembles the load carriers in the specified sequence, labels each container with a unique identifier, and delivers it within a tight time window.
The stability of planning is critical here: if the production sequence changes at short notice, the sequence information must be corrected in real time and communicated to all parties involved. Buffers are only provided to a very limited extent in the JIS concept, as any buffer can potentially disrupt the sequence. Faulty or swapped parts cannot simply be skipped — they block the production cycle.
- Sequence information is transmitted with sufficient lead time to allow the supplier to respond.
- Load carriers and containers bear a unique, scannable label that documents the position in the sequence.
- Deviations are detected and escalated via automated scanning and verification processes.
- Transport itself is closely timed and frequently linked to fixed milkrun routes.
What matters when selecting and designing a JIS setup?
Three aspects take center stage when planning a JIS supply chain. First, data integration: the quality of the sequence information determines everything. Transmission channels, formats, and latency times must be clearly defined and contractually secured. Second, disruption management: clear escalation processes and defined response times are needed to handle production changes, vehicle dropouts, or supplementary deliveries. Third, consequential error regulations: since sequence errors can cause line stoppages, the potential costs are high. Contracts with JIS suppliers therefore frequently include specific SLA clauses and penalty provisions, which vary from vendor to vendor. Determining which buffers between the sequencing point and the point of installation are permissible without jeopardizing the sequence is one of the key dimensioning questions when building a JIS concept.
