Having a clear "why" helps to ensure that everyone involved in the strategy is aligned and working towards the same purpose. It also helps to guide decision-making and can serve as a source of motivation and inspiration for employees.

For example, a company's goal might be to increase revenue by 20% within the next year. But why is that goal important? Is it because the company wants to expand its operations and enter new markets? Or is it because it wants to increase its profitability and provide better returns for shareholders? Whatever the reason, it's important to have a clear understanding of the "why" behind the goal, so that everyone can work towards achieving it.

In addition, having a clear "why" can also help to create a sense of purpose and meaning among employees. When employees understand the purpose behind their work, they are more likely to be engaged and motivated, which can lead to better performance and outcomes.

Overall, I believe that having a clear "why" is an important aspect of a good strategy, as it helps to ensure that everyone is aligned and working towards the same purpose.
