John Kotter uses his fable of a melting iceberg and its impact on a community of penguins to underscore the steps we can take to enact change within our own groups.

Sometimes, change seems impossible. You might notice something that poses a risk to your group, community, or organization, but the idea of taking action to address it can be overwhelming.

The fable of Fred the penguin, who alerts his community to the risk of their home iceberg melting and breaking apart, helps illustrate the steps it takes to enact change within a group.

Harvard Business School Professor Emeritus John Kotter is a leading expert in change management.

Originally published in 2006, Kotter's New York Times bestselling book, Our Iceberg is Melting: Changing and Succeeding Under Any Conditions, illustrates powerful steps to drive change in any organization.
