What potential obstacles might companies face when implementing the strategies from "Good Strategy, Bad Strategy" and how can they overcome them?

'Good Strategy, Bad Strategy' by Richard Rumelt has significantly influenced corporate strategies and business models by emphasizing the importance of clear, coherent strategies over vague objectives. It has taught businesses to focus on overcoming key challenges and leveraging unique advantages, rather than pursuing multiple conflicting goals. The book has also highlighted the dangers of 'bad strategy', such as fluff, failure to face the challenge, over-specification of goals, and designating goals as strategies, which has led many businesses to reassess and refine their strategies.

One of the most innovative ideas presented in Good Strategy, Bad Strategy is the concept of 'kernel' of a strategy, which includes a diagnosis, guiding policy, and coherent action. Another surprising idea is the emphasis on the importance of good strategic objectives, which should be an action that addresses the obstacles identified in the diagnosis. The book also highlights the importance of focusing on strategic advantages and leveraging them effectively. Lastly, the idea of 'bad strategy' is also innovative, where it discusses how strategies often fail due to fluff, failure to face the challenge, mistaking goals for strategy, and bad strategic objectives.
