Just-in-sequence

Concept from procurement logistics with the objective of delivering the right quantity of the right products in the right order (in sequence). Further development of the just-in-time principle in order to provide the delivered product or material synchronously with the production order.

Just-in-time

Organization principle and procurement strategy with the objective of waste-free realization of overlapping processes tailored to the specific needs. The right products should be procured at the right time and in the right quantity and provided for further processing. If this parts flows is practiced everywhere, the warehouse stock can approach zero. Today this principle is being further developed through just-in-sequence.
