If you are employed as the procurement manager of a company, you bear
the responsibility of managing the supply of goods in a way that will benefit the company.
Hence you are the point of contact between the company and it suppliers and held accountable for these major (3) issues:

1) Delay in the delivery time, even though the supplier is to blame.
(This could mean profit or loss).

2) Shortage in agreed quantity, irrespective of the cause.

3) Data management; as a mistake here could cost the company a lot of money.
An example is, puling out of the wrong price of previous purchase to be used in planning a new purchase.


THE EASY WAY OUT.

1) Take the bridge: Since you desire to minimise these costly problems, use the
Services of a "Supply chain and Logistics company". Do not leave that decision for your supplier to make.

*"Timely delivery and The delivery of agreed quantity of goods" are too valuable to leave for your suppliers.

2) Extension: In linking up with your suppliers you need to see the "Supply chain and Logistics company",
as an extension of your company. Without this perception, you would be unwilling to use their services.

* Buyers feel the effect of delayed delivery (10x) more than the suppliers.

3) Result: Observe how you are exempted from the pressure and delays other face at work.
