Hockey phenomenon in the hottest supply chain mana

The "hockey phenomenon" of supply chain management

in supply chain management, there is a kind of hockey phenomenon, that is, in a fixed cycle (month, quarter or year), the sales volume in the early stage is very low, and there will be a sudden increase in sales volume at the end of the period. Moreover, in a continuous cycle, this phenomenon will recur, and the shape of its demand curve is similar to hockey sticks, so it is called Hockey (hockey**-stick) phenomenon. In many companies, this phenomenon is very obvious, and their managers even think that this is the biggest problem facing their supply chain

the existence of hockey has brought many negative effects to the company's supply chain operation, mainly manifested in uneven busy and idle. At the beginning of the period, there were few orders, and the personnel and equipment were idle. At the end of the period, there were many orders, and the personnel and equipment worked overtime. They also had to seek external resources. The error rate increased and the service level decreased. In order to meet the demand for the next experiment, the production capacity and storage capacity of the enterprise need to be designed according to the maximum demand rather than the average demand, which will cause waste

the reason for this phenomenon should be in all links of the supply chain. Most consumers will not increase consumption at the end of the month (weekends may have an impact on consumer consumption). The main reason for this phenomenon is assessment: generally, according to the monthly assessment, the salesperson always tries to reach the final goal at the end of the month; Some assessment indicators are set and calculated according to the month when the running direction of the motor should be consistent with the direction 1 indicated by the arrow on the pulley cover. For example, the demand satisfaction rate of a fast-moving consumer goods enterprise: it is based on the rate of orders received in the current month and completed in the current month. Their order information itself has no time requirements, as long as it is completed in the current month, so they are always busy with orders by the end of the month. There are also some business operation factors: for example, the closing of financial accounts. After the implementation of ERP, the financial department will report the financial results on a monthly basis, and the accounts need to be closed once a month, causing the business department to rush to deal with the business before closing the accounts; Inventory counting may also be a reason for this phenomenon

hockey phenomenon occurs not only in long cycles, such as years, seasons and months, but also in smaller time cycles, such as weeks and days. Generally, I am busy at weekends. Generally, weekends are small peak sales; The logistics department is busy after 4 p.m. every day, because it is stipulated that the orders of the day must be processed on the same day. The orders of the day are the orders received from 4 p.m. to 4 p.m. yesterday. Many sales departments often send orders at the moment before the deadline. The logistics department finished processing the orders before work, and the logistics company sent the goods out in the evening

The hockey phenomenon with a long cycle is harmful to the supply chain and should be eliminated as far as possible. After exceeding the yield load, this is logically consistent with the demand equilibrium emphasized by Toyota production mode. However, for the short-term hockey phenomenon, it is beneficial to the optimization of the supply chain. The operation rhythm is formed by artificially setting some policies with poor weather resistance: for example, as mentioned above, the order is processed on the same day, and logistics generally does not process the order in the morning; P & G requires dealers to place orders every three days rather than at any time. This is an artificial short cycle hockey phenomenon, which is beneficial to the optimization of the supply chain. (end)
