There are seven CEOs working for your organization today

You have a relatively new CEO. Fifty-seven years young. Became CEO a year and a half ago at 56. Doing well. Came from inside. Consensus choice. Replaced a great decade long CEO. She has confided in the board that she will step down as CEO when she is 62. Assuming her party wins the election, she has plans for public service and is slated for a post as ambassador in the country she and her family love and want to retire in. That means that you, she and the board have five years to find and prepare her replacement. A replacement that will face a tougher, more competitive world with global challenges and increasingly complex issues. Why might this be difficult?
