Value stream engl.

The traditional value stream is about making waste visible in two key areas. In this case it is important that first the control and information levels are captured, as these are the starting point for all process-related change. In the next step, the processes that are required to produce the products are captured. So as to not get bogged down in the details when processing the numbers, data, and facts, it is helpful to first clearly formulate hypotheses on the basis of knowledge gained to this point. These hypotheses are then proved and disproved using targeted analyses.

The decimal when calculating process times or the like is not important. What is important here is to remember that the value stream can change at any moment. Buffers, inventory, even process times and cycle times change, because different variants always arise, including disruptions, breaks and other obstacles. The value stream achieves transparency and shows where there is waste and what is being wasted.

The processing time is worked out via visualization with the value stream methodology
Bildbeschreibung

Lead time is the time taken from the start of processing to the completion of a product *. It includes added value time (time in which added value is created for the customer) and waste time (time in which no added value is created for the customer)
