After leaving the electronics industry, I joined the metal and woodworking furniture industry.
This company's products include iron component manufacturing processes, which overlapped with my previous four years of experience as a production control staff in the steel industry. My supervisor openly told me that it was precisely because of my background in steel industry production control that they hoped I would join the team.
After going through nine months of immersion in the electronics industry, I felt as if I had returned to a familiar sector.
However, only after truly starting work did I realize that "related industry" and "familiar job" are actually two different things.
Although both are related to metal, every company's products differ, manufacturing processes differ, and production methods differ; even the materials, equipment, and scheduling logic are all different. For production control, the most important thing has never been memorizing a set of processes, but rather re-understanding the production model behind each product.
Production control is a role that requires accumulation. In addition to familiarizing oneself with product processes, work hours, and production methods, one must also understand every BOM sheet, every type of material, every usage quantity, and the supply-demand relationships between different processes. Often, simply knowing how a product is made is not enough; what matters more is understanding why it is arranged this way and what impacts changing the sequence would have downstream.
Therefore, even with relevant background, I still had to start over.
Now, every day I study the scheduling tables left by my predecessor in production control—not just following them, but trying to understand his thought process: Why was this job done first? Why was another delayed? How is balance achieved between materials and capacity? Behind every decision lies its own rationale.
What I truly need to learn is not operations, but thinking. Experience has indeed helped me avoid some detours; I don't need to start from zero with many material names, processing methods, or even the language used when communicating with on-site staff. But it is more like a foundation rather than a fully built house—the remaining floors still need to be constructed by myself.
In the past, I always thought that the more work experience one has, the easier job changes would be. Now I feel instead that the greatest value of experience is not sparing you from learning, but helping you understand how to learn—because you know which areas are key, what questions to ask, and where to begin dissecting when you hit a roadblock.
Every time you switch companies, it's like opening a new textbook; the chapters may be similar, and the language may share some common points, but the content is never exactly the same.
So now, I no longer rush to prove that I know everything. Instead, I remind myself to steadily build the foundation step by step, gradually understanding the products, familiarizing myself with the processes, and establishing my own scheduling logic.
I believe that true professionalism is not about immediately taking over in a new environment, but about having the ability to turn the unfamiliar into the familiar step by step even when starting over. This is my greatest challenge right now, and also the one thing I most look forward to accomplishing after enduring the pressure.
