In an organization with strong culture where certain values are widely shared, if the organization decides to adopt a different set of values, unlearning the old values and learning the new ones will be a challenge because employees will need to adopt new ways of thinking and behaving. For example, Home Depot had a decentralized, autonomous culture where many business decisions were made using “gut feeling” while ignoring the available data. When Robert Nardelli became CEO of the company in 2000, he decided to change its culture starting with centralizing many of the decisions that were previously left to individual stores. This initiative met with substantial resistance, and many high level employees left during Nardelli’s first year (Charan, 2006).
