In *Good Strategy/Bad Strategy*, Richard Rumelt clarifies the distinction between effective and ineffective strategies. He argues that a good strategy is a specific and coherent response to overcoming obstacles, harnessing power where it will have the greatest effect. Rumelt debunks elements of 'bad strategy' such as equating goals, motivational slogans, and financial targets with actual strategy. He introduces the 'kernel' of strategy, which includes a diagnosis of the challenge, a guiding policy, and coherent action. The book uses diverse examples from business, nonprofit, and military contexts to illustrate these concepts and emphasizes the importance of analytical rigor and focused effort in strategy development.

In this influential business book, Clayton Christensen shows how even the most outstanding companies can lose market leadership when they fail to adapt to disruptive innovations.

The book uses examples from various industries, including the disk drive, mechanical excavator, steel, and computer industries, to illustrate trends that lead to success or failure in the face of disruptive technologies.
