Why User Experience Is Harder Than Engineering [Podcast]

July 17 , 2026

A product can meet every specification, pass every technical test, and still disappoint customers.

That is because users do not experience specifications, engineering reports, or phase-gate approvals. They experience how quickly the product responds, whether its controls make sense, whether it feels comfortable and safe, and whether they can set it up without becoming frustrated.

In this episode of China Manufacturing Decoded, Adrian speaks with Paul Adams, Sofeast’s Head of New Product Development, about why user experience is often more difficult to validate than engineering performance.

Paul shares several real product-development examples and explains how early prototypes, independent user feedback, and prolonged real-world use can uncover experience problems before tooling and mass production make them expensive to correct.

You’ll learn:

* Why technical compliance does not guarantee a good user experience
* How packaging and button behavior can make a working product appear faulty
* Why safety limits and customer comfort are not always the same
* Which timing, feedback, accessibility, and setup problems to test
* Why engineers and product owners should not be the only testers
* How to incorporate usability feedback earlier in the NPI process
