Product Integration: Why Working Subsystems Fail When Assembled

Your electronics work. The firmware runs correctly. The mechanical components fit, and every subsystem has passed its individual tests. Then everything is installed inside the final enclosure, and entirely new problems begin to appear. In episode 335 of China Manufacturing Decoded, Adrian is joined again by Paul Adams from the group's contract manufacturer, Agilian Technology, to explore one of the most difficult stages of hardware development: product integration.   Show Sections 00:21 – When Individually Working Parts Fail Together 02:28 – Why Everything Works During Bench Testing 07:40 – What Changes When Integration Begins 08:39 – Designing the Product So It Can Be Debugged 10:16 – Integrating One Subsystem at a Time 13:45 – A Technically Working Product Can Still Fail 15:00 – The Hidden Impact of Heat Buildup 20:19 – The First Complete Build Is Only a Mini Milestone 21:39 – Solving an Enclosure Airflow Problem 23:53 – Paul’s Product-Integration Playbook 24:07 – Step 1: Integrate in Stages 24:52 – Step 2: Test Important Risks Early 26:16 – Step 3: Keep Debugging Access Available 27:18 – Step 4: Test the Way the Customer Will Use It 28:20 – Step 5: Treat the Enclosure as Part of the System 29:29 – Final Lessons From the Integration Process   Related content How Many Prototypes Are Needed Before We Get ‘Perfection?’ Transitioning to Manufacturing from Product Development | 2 Options Why does new product development take so long?
