Many companies actively push for second-source adoption, and the reasons go far beyond cost control. Supply stability and flexibility are just as important. But if the benefits are so clear, why does implementation often run into trouble? Based on real-world experience in electronics manufacturing, this article looks at the benefits, the challenges, and practical strategies to help companies create a win-win outcome.
