One of the most visible and essential elements of your job as a leader is to create an exciting, unified vision of the longer-term future for your company or unit. (We discuss this imperative in more detail in Ron’s book The Harvard Business Review Leader’s Handbook and in earlier articles.) This is difficult enough, but even once a vision is in place, many leaders fail to execute on it over the many years that it may require. For example, a 2018 study by McKinsey found that only 16% of companies that were committed to a multi-year process of digital transformation reported sustainable performance improvement.
