Changing an entire large organization is never easy; only about a third of all such transformations succeed. One problem many organizations run into as they implement a change program is faltering momentum because employees just don’t change the way they work. Sometimes they don’t want to, and sometimes the reason is a poorly structured plan that makes change harder. Our recent experience at a European retail bank shows the benefits of starting to implement change by focusing on the employees who have the most influence over the daily work that needs to change. This approach can ensure that a successful transformation happens faster and that employees remain engaged in the long term.
