Analyst Insight: The critical value-add of a manufacturing supply chain comes from constantly asking, "Can we make what we sell and sell what we make?" This is sales and operations planning (S&OP): a process of constant vigilance to meet customer commitments, while optimizing scarce working capital. Supply-chain optimization efforts can benefit from approaching projects as a hybrid of S&OP and supply chain. This places the focus on value creation over functional excellence. - Jon Kirkegaard, President, DCRA Inc.
