The Granddaddy of al mistakes

Michael Porter: The granddaddy of all mistakes is competing to be the best, going down the same path as everybody else and thinking that somehow you can achieve better results. This is a hard race to win. So many managers confuse operational effectiveness with strategy. Another common mistake is confusing marketing with strategy. It's natural for strategy to arise from a focus on customers and their needs. So in many companies, strategy is built around the value proposition, which is the demand side of the equation. But a robust strategy requires a tailored value chain—it's about the supply side as well, the unique configuration of activities that delivers value. Strategy links choices on the demand side with the unique choices about the value chain (the supply side). You can't have competitive advantage without both.
