How can a startup apply the kernel of good strategy to its business model?

A small business can use the key topics or framework covered in the book "Good Strategy, Bad Strategy" to grow by applying the three core elements of a good strategy: diagnosis, guiding policy, and coherent action. Firstly, the business needs to diagnose the problem or challenge it is facing. This could be anything from lack of market share to poor customer retention. Secondly, the business needs to develop a guiding policy to address the diagnosed problem. This policy should aim to create or leverage advantages. Lastly, the business needs to define coherent actions to implement the guiding policy. These actions should be specific, actionable, and directly linked to the guiding policy and diagnosis.

Some examples of companies that have successfully implemented the principles of good strategy as outlined in Richard Rumelt's book 'Good Strategy, Bad Strategy' include Apple, Amazon, and Google. Apple's clear diagnosis of the problem of complicated technology, their guiding policy of creating user-friendly devices, and their coherent actions in product development and marketing align with Rumelt's principles. Amazon's strategy of becoming the 'Earth's most customer-centric company' and their actions to achieve this also align with these principles. Google's strategy of organizing the world's information and making it universally accessible and useful, and their actions in developing search algorithms and other technologies, also demonstrate the principles of good strategy.
