CEO Succession Planning: How to Manage an Emergency CEO Transition and Appoint an Interim CEO
An emergency CEO succession plan helps the board respond quickly when a CEO departs unexpectedly or becomes unable to serve. This guide focuses on interim CEO selection, decision rights, communications, and transition readiness so the company can preserve stability during a sudden leadership event.
A well-defined CEO succession plan is one of the most critical safeguards an organization can have. While succession planning is often viewed as a long-term strategic exercise, its true value is realized during moments of uncertainty—especially in an unexpected or emergency CEO transition.
Whether due to sudden departure, incapacity, or other unforeseen events, organizations must be prepared to act quickly. The ability to execute a structured CEO transition can determine whether the business maintains stability or faces disruption.
