Illustration of a bottleneck in manufacturing, where the material is jammed upstream of the bottleneck and is missing afterwards. A bottleneck in process C leads to blocking of products and processes before the bottleneck and starving of products and processes after the bottleneck. The products (green balls) are piling up before the bottleneck process C, and are missing afterwards.
