This is a well written article which is accurate.  Typical supply chain strategy often includes low cost, flexibility, global, NPI, technology, cycle time, etc.  This is not enough, the strategy needs to align and support the overall business strategy.  Hence, there needs to be a clear business strategy (not always present).
"An effective supply chain strategy must focus on aligning the business and supply chain strategies, designing the differentiators to build advantage, and pursuing a coherent technology strategy to support them—we call this supply chain nirvana."
