The reduction of inventory along the added value chain as well as short lead times in combination with low costs are among the main goals of globally-operating automobile manufacturers and their suppliers in order to satisfy the increasing individualization of customer orders. An effective means for meeting these requirements is the just-in-time delivery and provision of high-quality parts at the mounting cycle of the production line.

In just-in-time delivery (JIT), parts are provided to the customer at the exact place and time of requirement without previous storage, in just-in-sequence delivery (JIS) the required sequence is met as well.

JIS/JIT provision entails stricter requirements regarding the parts flow from the supplier to the customer and requires a continuous information flow across all added value steps. The uninterrupted information flow forms the basis for the production time of parts at the supplier, the determination of delivery date and sequence as well as the financial transactions. Thus, precise planning of the material and information flow is the decisive factor in successfully introducing JIT/JIS delivery. This includes designing both transport concepts from the supplier to the mounting point and container cycles. The configuration of the information flow comprises defining the required information as well as the manner and sequence of its transmission between all parties involved in the process. This results in a complex requirement profile for IT systems.

 

Methods

For switching existing delivery concepts to the JIT/JIS strategy as well as for integrating new products into existing JIS/JIS delivery concepts, we rely on value stream mapping for analyzing the material flow processes. In line with the lean philosophy, we capture the entire supply chain from supplier to customer together with process experts from all added value steps, analyze them and define a desired process together. For an uninterrupted design of the corresponding information flow, we particularly utilize flow and context charts.

In order to structure and document the requirements regarding the future desired process (e.g. container concepts, IT systems, etc.) we use among other things requirement catalogs. The requirements lay the groundwork for implementation and are generally stipulated in specification documents. They also form the basis for a test phase and later acceptance test.

The implementation and test phase of a planned JIS process is particularly important, since JIT/JIS processes require a high degree of process stability. To ensure this stability, we also support to our customers in the implementation of the planned measures.

Continuous project coordination and supplier management are the prerequisites for successful realization. For this purpose, our consultants closely cooperate in interdisciplinary teams with your staff and the people responsible for planning at the suppliers' end.
