In today's rapidly changing business landscape, the competition among modern enterprises has evolved into an all - round battle of supply chain strength. More and more insightful people have acutely realized that supply chain competition is the core of enterprise competition. The efficiency and effectiveness of its management are like the lifeline of enterprise development, profoundly influencing a company's competitiveness in the market and even directly determining its survival and prosperity. This is no longer a concept that requires excessive elaboration but a truth deeply understood by numerous enterprises through arduous exploration.
In the grand landscape of supply chain management, how to achieve efficient collaboration between suppliers and the company itself is undoubtedly a major topic that demands in - depth exploration. Among them, quality collaboration, a specific area, is gradually emerging from the shadows and attracting increasing attention from more and more enterprises. It is like a gold mine hidden deep within the enterprise, long overlooked but containing huge potential value. Quality collaboration encompasses every aspect of supplier quality management, from the source control of raw materials, to quality monitoring during the production process, and finally to the inspection and release of the final products. Every link is closely connected and interlocked.
Today, we will focus on an important aspect of quality collaboration - suppliers' shipment reports, uncovering the intricate problems and opportunities behind them.
In the actual operation of the supply chain, there is a rather interesting but thought - provoking phenomenon. For each batch of materials, suppliers will provide shipment reports, and without exception, all the reports indicate that the products are qualified, as if everything is going smoothly without any flaws. However, the reality is far from being so rosy. Most customers, even when holding seemingly flawless shipment reports from suppliers, still conduct incoming material inspections meticulously before the materials are stored in the warehouse or fed into the production line. What's more serious is that unqualified products are frequently discovered during the inspection process, and in some cases, entire batches of materials are found to be unqualified. As a result, production stoppages due to lack of materials are not uncommon. This inevitably makes people ponder deeply: Why do customers still insist on inspecting the goods despite having seemingly impeccable shipment reports? What exactly are they worried about? And what signals does this phenomenon convey to us?
To ensure the receipt of qualified materials, SQE (Supplier Quality Engineer) in enterprises has painstakingly invested a great deal of effort and employed a variety of management methods to comprehensively control suppliers. The shipment report, as an important management tool among them, is intended to prompt suppliers to earnestly fulfill their inspection responsibilities and guarantee that the delivered goods are of qualified quality. However, the actual effect has fallen short of expectations. In the eyes of some suppliers, providing a shipment report seems to be nothing more than a routine process, lacking the necessary rigor and earnestness.
So, before delving into how to improve this situation, let's first conduct an in - depth analysis of the problems that suppliers may encounter in the shipment report process.
Firstly, when the product data is unsatisfactory or the products themselves are unqualified, some supplier management teams may instruct inspectors to falsify data, attempting to deceive customers through such improper means and cover up product quality issues. Secondly, some supplier inspectors are not serious about their work and are lazy. They fill in data randomly. It should be noted that the management teams of such suppliers may not have the subjective intention to deceive customers, but the improper behavior of inspectors still poses potential risks to quality control. Thirdly, the inspection standards and methods adopted by suppliers may differ from those required by customers, which can lead to significantly different judgments on product quality between the two parties. Fourthly, the inspection methods used by suppliers may be incorrect, which will undoubtedly render the inspection results untrue and unreliable. Of course, in addition to these, there are also some other reasons that may cause problems in the shipment report.
Next, let's narrow down the scope of our discussion. Regarding the inspection of most dimensions and appearances, if you have more than 10 years of rich experience in supplier management, based on your intuitive industry sense, which of the above problems do you think is more likely to occur?
In fact, due to the different characteristics of industries, the varying scales of enterprises, and the diverse management methods of enterprises, these factors can lead to significant differences in the probability of problems occurring. However, in most cases, the second problem, that is, the phenomenon of supplier inspectors randomly filling out shipment reports, has a relatively high probability of occurrence.
After clearly identifying the root causes of the problems, we can then take targeted measures to crack this quality control problem.
Currently, an effective solution is gradually emerging, which is for customers to implement QMS (Quality Management System) software. With the help of this advanced software platform, suppliers can conveniently enter inspection data and then automatically generate shipment inspection reports. More importantly, the customer side can view suppliers' shipment reports in real - time, without having to wait until the goods are delivered to obtain relevant information. Moreover, customers can also flexibly decide whether to display their own inspection results to suppliers according to their management needs, thus realizing real - time interaction of inspection reports and building a bridge for quality information communication between both parties.
What tangible benefits can this real - time viewing of suppliers' shipment inspection reports bring to enterprises?
For measured values, we can directly compare the measurement results of suppliers with those of customers. If the measurement results provided by suppliers are almost perfect, while the customer's inspection results show significant fluctuations, then the problem is self - evident. In this case, the data provided by suppliers is very likely to be problematic, probably falsified or the measurement process has serious errors.
The same is true for counted values. Usually, suppliers conduct shipment inspections first, and then customers conduct incoming material inspections. Theoretically, after a certain period of accumulation, the total proportion of defective items counted by suppliers should be greater than that counted by customers. If the number of defective items counted by customers is greater than that of suppliers, there must be something wrong. It should be noted that suppliers' shipment reports often appear to be flawless, without any records of defective items. Suppliers may argue that they have removed the unqualified products discovered during the inspection, so there are naturally no unqualified items in the report. However, if this is a full inspection operation, such a practice may be understandable, but if it is a sampling inspection, this behavior is undoubtedly data fraud.
In addition to the above comparison methods, we can also judge the authenticity of data by observing the pp value (Process Performance Index) of suppliers. For products such as injection - molded and stamping parts, the production process is relatively stable, and the pp value usually remains within a relatively stable range. We can select some key data indicators for continuous monitoring. If we find that the pp value of suppliers fluctuates abnormally, jumping up and down, then it is basically certain that the supplier inspectors did not take the data filling seriously and are likely to have fabricated the data randomly.
Furthermore, comparing the pp and ppk values (Process Capability Index) of suppliers and customers is also an effective method. If the difference between the two is large, it indicates that there is a problem with at least one party's data. Considering the actual situation, since suppliers often have an impulse to falsify data in order to ensure the smooth shipment of goods, more often than not, it is the suppliers' data that is problematic.
Whether it is a supplier inspector or a customer inspector, forging perfect false data is no easy task. Firstly, the forger must possess certain mathematical knowledge to fabricate seemingly reasonable data. Secondly, the workload of forging data far exceeds that of actual measurement. Therefore, the key to the problem is that if data fraud can be detected in a timely manner at a relatively low cost, this kind of bad behavior can be effectively curbed to a certain extent.
When suppliers clearly know that customers can conveniently compare various data, they will surely restrain their behavior and will no longer act recklessly and wantonly as they did before.
However, in the actual operation of enterprises, there are often numerous suppliers, a wide variety of purchased materials, and a large number of key items. Even though the QMS software has achieved more convenient data comparison than ever before, in the actual operation process, the efficiency still seems to need improvement. To address this issue, we can further optimize the management process through system settings. Once the system detects a significant difference between suppliers' data and customers' data, it will automatically trigger an early warning mechanism and promptly notify quality management personnel. In this way, quality management personnel no longer need to spend a great deal of time and energy comparing data one by one, and their work efficiency has been greatly improved.
Is the function of real - time viewing of suppliers' shipment inspection reports only limited to this? Certainly not.
For assembled matching parts, such as the fitting problem between shafts and bushings, it has always been a difficult point in the production process. The fit between the two is either too loose, resulting in product instability, or too tight, affecting the assembly efficiency and disrupting the normal production rhythm. Suppose there are 3 suppliers for shafts and 2 suppliers for bushings. Once a fitting problem occurs, suppliers tend to shift blame onto each other. At this time, as the "judge," the customer, due to the lack of comprehensive and accurate data support, finds it difficult to determine whose responsibility it is. However, if all suppliers' inspection data can be comprehensively compared with the customer's own inspection data, it will be clear at a glance which supplier's data is perfunctory and randomly filled, and which supplier's data quality is poor, and the root cause of the problem will also be exposed.
Similarly, in managing the dimensional changes of suppliers' injection - molded parts, especially the precise control of multi - cavity dimensions, real - time viewing of shipment inspection reports also has significant advantages. By comparing the data from all parties, enterprises can not only clearly understand whether suppliers are seriously recording data but also quickly identify the cavity with the largest dimensional change, and take corresponding preventive measures in advance to effectively avoid production stoppages and other problems caused by dimensional issues in the subsequent production process.
