Coordination between purchasing department and production department: In order to ensure the stability of raw material supply, purchasing department and production control department need to exchange information frequently. The production control department should inform the purchasing department of the product production plan and material demand plan as soon as possible, so that the purchasing department has sufficient time to find the source of goods and negotiate with suppliers. The purchasing department must also inform the production control department of the required procurement and delivery time and the possible changes after ordering. If there is any change in the quantity or schedule in the production plan or procurement plan, both parties shall notify each other in time so as to make appropriate adjustments and cooperation in time.
Coordination between purchasing and quality control departments: basically, purchasing personnel must be familiar with relevant quality standards in order to buy suitable things from suppliers. Because of direct contact with suppliers, the purchasing staff can help the quality control department to establish a set of inspection standards that suppliers can cooperate with. The quality control department shall also inform the buyer of the inspection results so as to evaluate the suppliers.
Coordination between purchasing department and manufacturing department: purchasing department provides materials needed by manufacturing department, which are closely related, but have different status. Usually, the manufacturing department hopes that materials can be supplied quickly to avoid material downtime; The purchasing department hopes to have enough time for negotiations to reduce costs. Therefore, we must respect each other, fully coordinate and not be impulsive in the time of purchase and delivery. In addition, the positions and opinions of the manufacturing department and the purchasing department may be different about the decision of "self-made" or "outsourced". At this time, we should consider the factors according to the cost analysis results and strategies, and negotiate with each other objectively.
Coordination between purchasing department and technical department: when designing material specifications, technical department should not overemphasize the pursuit of ideals and ignore price and market factors; Moreover, the purchasing department should not overemphasize the price factor and ignore the quality requirements. Therefore, the technical department should consult the purchasing department, and the purchasing department should also suggest appropriate specifications and standards according to market information. In short, the two must work closely together. Procurement can proceed smoothly in the future. In addition, in order to establish standardization and collect the benefits of large-scale procurement, the technical department should consult the procurement department before design to minimize the types of materials. The two should cooperate closely to form a good interactive relationship. In addition, in the design of new products, the purchasing department should provide the latest information about material specifications, properties and prices at any time for the technical department's reference. However, at present, the use of materials should not only meet the requirements of consumer protection, but also meet the standards of environmental protection and occupational safety and health, which makes the design of engineering specifications more stringent, thus limiting the opportunities for procurement personnel to use alternative materials or products. Therefore, the engineering and procurement departments must strengthen contact so as not to violate public safety and interests.
