You need to choose suppliers and partners in this way: apply the "QCDS" development standard, which is also the basic standard for selecting suppliers.

The four letters "Q, C, D and S" in the basic principles of supplier development stand for quality, cost, delivery and service respectively, and they are juxtaposed and equally important.

First of all, product quality is the foundation, and suppliers should have a stable and effective quality assurance system, as well as equipment and technology needed for specific production.

Secondly, "cost and price", enterprises should have a set of rigorous cost analysis methods for the products involved, and the cost savings should not only include their own costs, but also take into account the costs of suppliers, so as to achieve a win-win situation.

In terms of delivery, it is necessary to determine whether the supplier has sufficient production capacity, whether the human resources are fully equipped, and whether there is potential for further release of production capacity.

In addition, we should pay attention to the service ability of suppliers, that is, pre-sales service and after-sales service.
