How have performance metrics, such as facing fill or network fill rates, developed over the past two decades?

There is little question that service levels have increased significantly for OEM parts distribution. As such, carmakers set performance objectives that are today much higher than 20 years ago. For example, most carmakers in the US consider the benchmark ‘facing fill rate’ – the percentage of dealer orders that can be served by standard order from its nearest regional parts centre – to be around 95%. For ‘system fill’, which is the ratio of orders that can be filled from across a given network (including rush orders), the ratio is now around 98%.
