Operational Excellence targets are typically changing every year for an organization based on changing dynamics of their marketplace, increased demands from customers, more intensive competition, etc. So even if you are a market leader today, companies cannot rest on their quest for Operational Excellence. It’s a continuous journey with new dimensions of excellence and new targets as the journey progresses.
