17 years of quality work have cultivated an "intuition for problems" deeply ingrained in one's actions
In the 17 - year daily life of a quality control person, there is no slogan - like "Quality First". It's all about being "persistent" in specific scenarios: When the smell of machine oil still lingers in the workshop in the early morning, I'm already standing in the incoming material area with a vernier caliper, measuring the diameter of each batch of stainless - steel parts to an accuracy of 0.01 millimeters. Even a slight deviation means sending the parts back to the supplier for re - work. Under the desk lamp in the office late at night, I look at the microscopic photos of failed parts, circle the crack sources with a red pen, and then dig out the process records from three months ago to check one by one if "the heat - treatment temperature was not well - controlled". I even squat beside the production line with the team leader, using a stopwatch to time each step of the operation, just to figure out "why the defective rate of this workstation is 1% higher than that of the adjacent one". These fragmented experiences are not burdens. They are my most practical understanding of "quality": It's not the "99.9% pass rate" on the report. It's the instinct of "asking one more 'why'" in every link and the obsession of "blocking errors before the customer receives the product".
The expectation for transferring to the technical department is a value leap from "finding problems" to "creating a problem - free situation"
The urge to join the technical department stems precisely from this obsession with the idea of "taking one more step forward". In the past, when I was involved in quality control, my role was that of a "problem hunter" – when customer complaints came in, I would investigate the causes; when there were piles of defective products, I would find out who was responsible. It was like a firefighter waiting for the fire alarm to ring. Now, I'm supposed to be a "problem architect": cross out the risk items in the DFMEA one by one during the design phase, and set the strictest tolerances for assembly clearances during Prototype verification, so that "it won't go wrong" replaces "it mustn't go wrong". For example, in the past, when I saw customer feedback saying that "the product shell is prone to cracking", I could only check the temperature of the injection molding process. Now, during the design stage, I can increase the wall thickness of the shell from 2 mm to 2.5 mm and change the fillet radius from R1 to R2, thus solving the problem at the root. This transformation from "making up for problems afterwards" to "creating solutions beforehand" is like attaching a "design knife" to the "quality ruler" in my hand. In the past, I could only measure the problems; now, I can personally prevent them from occurring before the products leave the factory. The sense of value brought by this "active creation" makes me more eager than any promotion.
The uneasiness in the heart stems from the attachment to the comfort zone and the unease about the new battlefield
But when I put aside my familiar quality work, I can't help but feel a little sad inside. It's not that I'm reluctant to leave the position, but rather the habit of "doing things without thinking." For example, when I tidied up my workstation yesterday, I found that box of gauges I've used for five years. The metal jaws still retained the warmth of my palm, and I recalled the way my thumb used to press habitually every time I measured with it. Another example is during the weekly meetings with the quality team. When the words "batch rejection" were mentioned, everyone would instinctively look towards the warehouse – that's the place where we handled three large - scale batch rejections together. Even the process of handling customer complaints, I can name every single step with my eyes closed: first, check the historical records in the OA system; then, review the production line surveillance footage; finally, ask the supplier for the material report. These "muscle memories" are like an old sweater in winter. They're warm and reassuring, and they make me can't help but wonder: will it be a bit cold if I take it off and put on a new one?
There is also the uneasiness brought by the strangeness of the technical department. In the past, when looking at design drawings, I only focused on whether they meet the quality standards — for example, whether the dimensional tolerance exceeded the limit and whether the material grade was correct. Now, when I have to draw the drawings myself, I need to consider whether this structure will be difficult to process and whether that hole position will affect the assembly. In the past, when reviewing DFMEA, I only pointed out incomplete risk identification and unimplemented preventive measures. Now, when I have to write the DFMEA myself, I need to predict from the design stage whether the product will be dropped during customer use and whether it will deform when the ambient temperature is high. In the past, when communicating with the technical department, I often said There is a problem with your design. Now, I have to say with them How can we make the design right. These areas that need to be learned and need to be changed are like the newly sprouted thorns in spring, pricking my heart with a bit of itchiness and a bit of panic — I'm afraid that I can't keep up with the pace, that my previous experience won't be useful, and that I can't shed the label of quality person.
Both expectations and sorrows are the footnotes of growth
But thinking deeper, this "expectation" and this "unease" are actually the same thing: We have expectations because we see broader values, and we feel uneasy because we care about our own growth. The "intuition about problems" developed through 17 years of quality work is exactly what the technical department needs the most - being able to foresee risks in advance during the design phase and accurately identify loopholes during the verification phase. This is my unique advantage; and that bit of "unease" just shows that I'm not numb yet and still want to step out of my comfort zone. Just like when dealing with quality issues in the past, the happiest moment was not finding the cause, but seeing the improved products leave the factory smoothly. Now, I want to transform this happiness from "solving existing problems" to "creating designs without problems."
I'm going to report to the Technical Department next month. There are still sticky notes on my desk that my colleagues from the Quality Department gave me. It says, "We're relieved that you're going with the 'quality radar'." —Yeah, I haven't let go of the past. Instead, I'm taking the accumulation from the past to explore broader horizons. There are more expectations than melancholy in my heart because I know that so - called growth means turning the "familiar" into confidence and the "strange" into a new kind of familiarity.
