Just-in-time refers to a production system in which the parts used are delivered by the suppliers exactly when they are needed for production according to precise planning. This allows the provision of materials to be optimized (largely eliminating stocks and thus reducing capital commitment). The just-in-time principle is used, for example, in the automotive industry and production-oriented companies, but it can easily be generalized as a general principle (e.g. also for the provision of information).
