German purchasing departments measure their suppliers by Liefertreue, delivery fidelity. The business glossary Welt der BWL gives the formula: orders delivered on schedule divided by all orders. A delivery counts as on schedule only if it comes nicht verspätet oder verfrüht, neither late nor early. Liefertreue can also decide supplier awards. In 2013 the machine builder Zahoransky gave its Business Partner Award to suppliers that had proved especially reliable, insbesondere hinsichtlich Qualität, Liefertreue, Innovationskraft und Preisverhalten, especially in quality, delivery fidelity, innovation and pricing.
