Introduction The book ‘Our Iceberg Is Melting: Changing and Succeeding Under Any Conditions’ by John Kotter entails an analysis of the importance of leadership as one of the management practices that individuals and organizations should incorporate. The book uses a simple metaphor ‘Our iceberg is melting’ to illustrate the fact that one can perform well in a dynamic environment. The story relates to colony of penguins within the Antarctica region. The penguins had been living together peacefully for a long period and did not perceive the need to change. One day, a curious penguin by the name Fred identified a shocking phenomenon that would threaten their existence. The iceberg which was their home was melting. Despite warning the other penguins of the eminent danger, no one took him seriously. Considering the fact that Fred did not have any authority within the colony, he realized the need to initiate change. To achieve this, he approached another penguin by the name Alice who was more open-minded and flexible (Kotter, 1996, p.5). The fable is used to illustrate how people react to change. The tale depicts a number of elements which include confusion, insight, a heroism and resistance to change. Additionally, the story also illustrates the challenges that are encountered on a daily basis in an effort to implement change and how to deal with them. Through the fable, the author shows that penguins are more effective in dealing with real challenges compared to human beings. He achieves this by illustrating the steps that the penguins took in order to resolve the dilemma. These included effective problem identification, realization of the need to resolve the problem urgently, integration of teamwork, and thinking outside the box. In an effort to resolve the problem, the penguins experienced a number of problems such as skepticism. However, the penguins were able to adapt to a new way of life through effective selection of choices.
