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.
