A startup customer approached SCM Solution to support the product development process. Our client is an early-stage startup focused on smart home solutions for urban households. Their flagship product, a smart lock, is designed to integrate seamlessly with Wi-Fi and Bluetooth, allowing users to control door access remotely through a mobile app. With limited in-house hardware development resources, they relied on overseas manufacturing partners and needed strong support to manage the product testing and quality assurance process.
While the initial product concept was strong, the customer faced challenges in testing the electronic functions and ensuring reliability before mass production. That’s where we stepped in.

Our Client’s Challenges
While the startup had a clear product vision, they faced several challenges:
- Unclear product requirements that led to inconsistent factory understanding
- Lack of internal testing expertise, especially for functional hardware testing
- Communication gaps with the factory regarding test expectations and pass/fail standards
- Difficulty in identifying issues in the PCBA due to limited lab and diagnostic tools
- Concern about launching without thoroughly verifying real-world functionality
They needed a partner who could bridge the gap between engineering and manufacturing, someone who could define a testing process and guide the factory to execute it properly.
How Do We Help?
SCM Solution partnered with the customer and their factory to:
- Write clear product requirements and test plans in parallel
- Collaborate with engineers and the factory to conduct functional testing
- Identify and troubleshoot multiple issues in the PCBA (Printed Circuit Board Assembly)
- Provide continuous feedback and updates before mass production begins
Key Actions Taken
| Task | Description |
| Defined Requirements | Translated customer expectations into detailed product requirements that could be tested. |
| Built a Functional Test Plan | Designed test cases for Wi-Fi, Bluetooth, locking mechanism, LED indicators, battery response, and mobile app connectivity. |
| Detected PCBA Errors | Found signal issues and firmware bugs during Wi-Fi/Bluetooth switching under real-world conditions. |
| Iterated Rapidly | Worked closely with the factory to fix issues and re-test multiple prototypes. |
| Pre-Mass Production Validation | Ensured the product met functionality and reliability targets before the final build. |
Key Learnings
- Writing the test plan alongside product requirements helped prevent vague or incomplete design specs.
- Early and repeated function testing of PCBA helped identify critical design flaws that could have been costly if discovered after production.
- Close coordination with the factory’s engineering team was key to fast iteration and successful problem resolution.
Outcome
Thanks to the proactive testing strategy, the smart lock passed all functional tests before production. The customer was able to confidently launch a reliable product, minimize warranty risks, and meet go-to-market timelines.
