Depending on the product you produce, the sector you are in, and the customer base you are addressing, the length and shortness of the delivery time are important.
Especially those who manufacture for sectors such as automotive know well that the punctual delivery rate followed as KPI (Key process indicator) is recalculated and monitored in each shipment. It is a parameter that is calculated and sent to you by the main customer every 3 months at worst, and is queried if you fail to meet the targets (95% and above).
On-time delivery is important, but not so easy.
I have tried to briefly discuss some issues that prevent you from delivering on time with a fishbone below.
