I. Cause: "Formula suspicion" of product abnormality
Last week, we received an abnormal feedback from the Quality Department: the weather resistance test of a certain batch of Model B precision plastic parts failed to meet the standard. The original requirement was that the color difference ΔE ≤ 1.5 after 72 hours of UV lamp irradiation, but this batch of products reached 2.8 in only 48 hours, far exceeding the standard. More importantly, the component spectral analysis showed that the content of the anti-UV additive (Model: UV-327) was 18% lower than the reference value. Considering the small-batch fluctuations in the supplier's deliveries over the past three months (for example, the raw material batch numbers did not match the contract 3 times), we concluded that it was highly likely that the supplier had modified the formula and replaced the originally specified German BASF raw materials with low-cost domestic additives. To confirm our speculation, we urgently arranged this on-site audit.
II. Morning review: Key information deliberately "diluted"
My boss and I didn't arrive at the other company's factory until nearly 11 a.m. The night before, the reception staff of the other side repeatedly emphasized that "there will be a video conference with the Japanese headquarters in the morning. It is recommended to arrive half an hour later." The first stop of our on - site inspection was the assembly workshop. The equipment was running normally. However, when we asked to check the production records of Model B for that day, the production supervisor immediately waved his hand and said, "Today, we are producing auto parts for Customer C. Model B hasn't been put into production this week." Then we asked, "Can we go to the formula workshop to see the raw material ratio?" The response from the other side was even more straightforward: "The formula area is the core of the technology. According to the regulations of the headquarters, only Japanese engineers can enter. We just signed a confidentiality agreement last month."
It was already half past twelve. The "Japanese coordinator" beside us (later I learned that he was a Chinese who had worked in a Japanese company for six years and could speak fluent Japanese) began to glance at his watch frequently. "It's already 40 minutes past 12. The food in the canteen will get cold soon. Let's go for lunch first and conduct a detailed inspection this afternoon." The urge in his tone was hard to hide. It was less an invitation to lunch than an attempt to disrupt our rhythm of checking the records.
III. Breakthrough after lunch: The truth exposed by the "low - level fakes"
After a simple standardized meal (two vegetarian dishes and one meat dish, tasting like the "big-pot cooking" in a factory canteen), we returned to the meeting room at two o'clock and directly opened the formula record folder provided by the other party - this was what they called the "complete record for nearly a month".
The first folder has 50 pages, with dates ranging from the 1st to the 15th. All are printed electronic records in a neat format, with electronic signatures of the operator and quality assurance personnel. However, when I turned to the page of the 10th, I suddenly paused: this page was handwritten, and there were obvious creases on the edge of the paper, as if it was inserted later. Moreover, the handwritten "raw material batch number" (such as "UV - 327 - 230518") was inconsistent with the font of the printed pages before and after - the printed pages used the Song font, while the handwritten page used the Kai font. Then I turned to the second folder (from the 16th to the 30th), and the same situation occurred: the record on the 22nd was also handwritten, and the signature columns of the two handwritten pages were exactly the same - even the position of the pauses in the signature of "Wang Qiang" didn't change, obviously the same person traced it twice.
The boss put the record on the table, his voice tinged with a bit of helplessness. "This forged document is so half - hearted. If they really wanted to hide it, they should at least have someone else sign it, right?" I scraped the ink on the hand - written page with my fingernail and found that it wasn't completely dry yet, which meant it had been filled in in the last couple of days.
IV. The other party's concealment: Unconcealable "signs of nervousness"
When we pointed to the record and asked, "Is this handwritten part on the page an addition?" the production supervisor of the other side immediately changed his complexion. He nudged the quality assurance supervisor beside him with his arm and said, "Regarding this issue... the quality assurance department knows better. Let him explain it to you." But the quality assurance supervisor just stared down at the tips of his shoes and couldn't say a word for a long time - even the tips of his ears turned red.
When I asked again, "Why isn't there a seal from the raw material supplier in the records of Model B?", the other party's answer was even more vague: "Maybe the supplier forgot to send it. We'll make it up later." But I noticed that while saying this, his fingers kept tugging at the corner of his clothes - a typical "nervous when lying" reaction. Even more interesting is that when we proposed to "check the incoming goods ledger of the raw material warehouse", the other party suddenly said, "The warehouse keeper is on leave today, and the key is with him" - clearly not wanting us to conduct the check.
V. Results: An Obvious "Rectification Opinion"
At the end of the review, we put forward three "written opinions":
1. Provide the complete formula records of Model B products for the past month within 3 days (including the original data of electronic records, the approval process of handwritten records, and the stamped confirmation letters from raw material suppliers).
2. Submit the headquarters document regarding "access rights to the formula workshop" and explain why we, as core customers, are unable to enter.
3. Issue a written explanation regarding the "handwritten supplementary entry" issue and submit a rectification plan (including how to prevent similar situations from happening again).
When the receptionist on the other side took the suggestion form, their hand trembled a little. They said, "We'll implement the suggestions as soon as possible," but kept avoiding our eyes all the time. Obviously, they knew better than anyone what the subtext behind these "suggestions" was: We've already got the evidence that you changed the formula; we just didn't expose it to your face.
VI. The only affirmation: The eye - catching "logo management"
However, the other party's logo management is truly worthy of praise. All the raw material barrels in the workshop are pasted with labels containing QR codes. By scanning the codes, one can view the place of origin, batch number, and in-factory inspection reports (such as the import customs declaration for UV - 327). The turnover boxes for semi - finished products use colors to distinguish their status: red indicates pending inspection, green means qualified, and blue represents rework. Even the markings on the ground are made with reflective paint. Even when the lights are turned off at night, one can clearly see the boundaries of the raw material area, production area, and finished product area. The signs for the fire exits are even more considerate: not only do they have a fluorescent coating, but there are also arrows marked "Emergency Exit →" beside them, which is much more professional than the "ambiguous signs" in many factories.
Later, I asked the administrative director of the other party, "How did you make your signs so standardized?" He replied, "It's a requirement from the Japanese headquarters. Every label must be 'traceable and identifiable'. Even the trash cans have to be labeled with 'Recyclable' and 'Non-recyclable'." — I have to say that Japanese companies' obsession with details is really something.
During this review, we didn't have an open confrontation on the spot, but the other party knows well in their heart: next, they either need to present evidence that "the formula hasn't been changed", or accept our demand for a deduction or a replacement of the supplier. As for those records of "low - level fakes"? They are just a laughable attempt to hide something by making a show of concealing it.
