Leaders talk about change, but are not very good at it. The track record of the world’s top firms show that most fall by the wayside within one generation: from global domination to oblivion in 25 years. They do not fail because the leaders become dumb. They fail because they are unable to change with a changing world: new technology, new business models, new competitors come in and change the rules of the game. The giants find it hard to abandon the success formula that had served them so well in their growth phase. Their success formula turns to poison: first the formula fails to work and then it kills them.
