A major influence on the cost of a product is the time it takes to make this product. Traditional cost accounting can grasp part of this relation, but misses many critical aspects of having a faster time to the customer. Rajan Suri analyzed this relation empirically. Based on a data set with industrial data he determined an empirical mathematical relation between the turnaround time to the customer (or replenishment time) and the product cost for the entire value stream. This paper modifies the approach by Suri to be applied also to segments of the value stream, creating a relation between the cost within of a segment of a value stream and the time it takes for a part to pass through this segment of a value stream. This allows the estimation of the improvement in cost and the reduction in turnaround time also for sub-segments of the value stream, helping decision makers to better understand the impact of their decisions.
