As someone involved in factory sales person, is it necessary to understand drawings? I think it’s still important to learn a bit, as this allows for a quick understanding of customer needs and assessment of whether there will be any issues during subsequent processing. Knowing a bit of technical information can also help in providing quicker responses to customer inquiries during communication. I remember a colleague in the past who was excellent in interpersonal skills but couldn’t understand drawings, so he didn’t know whether we could produce certain items or if they would be easy to make. Every time he communicated with customers, he either had to take an engineer with him or send the drawings back to the company to consult with the engineering team. If it was a non-engineer interacting, it wasn’t too bad, and it didn’t give off an unprofessional vibe. But if it was an engineer, discussing details would require contacting external personnel, making the communication fragmented.In general, if a customer just needs a simple lining with a hole or a groove, it essentially doesn’t require technical knowledge; a basic blueprint can be understood by those who have had a high school education. However, if dealing with irregular products, a certain level of understanding of technology and manufacturing processes is necessary; being able to assess from the drawings whether the product can be made, if it’s difficult to make, and how to proceed is important… Knowing this provides assurance, enabling smoother communication thereafter. Of course, for non-technical personnel, a general understanding is enough; for instance, being able to open drawings with software and knowing how to measure is sufficient. As non-technical personnel, the main focus should still be on business rather than technology. As long as the quality of the goods delivered to customers is good and the service provided is satisfactory, that’s enough. Professional matters should be left to professionals; let the technical and production teams handle the foam linings more effectively, while maintaining enough foundational knowledge to engage with customers and answer their queries properly. Understanding some basic drawings is still very necessary to ensure smooth order and production processes.
