Some years ago, Richard Rumelt wrote about good and bad strategy. A bad strategy is coming in different shapes and sizes. Examples he provides are:
A good strategy, on the other hand, is based on a sound diagnosis, a general guiding policy and a coherent package of measures.
He does not say what these look like and for how long the strategy is a good and valid strategy. Certainly this is something that needs to be adapted to the concrete context.
When I look at these points, they are solid, well-founded and based on good arguments. The situation is not overly complicated by academic frameworks or models that only cover a limited number of aspects. Frameworks or models such as Porter's 5 Forces, SWOT and Business Model Canvas can help to reach a conclusion, but they are no substitute for the diagnosis, the formulation of the guideline and the package of measures.
The way to the result is to ask questions. Questions about your value proposition, your stakeholders, your unique insights and the inner logic of your arguments. The questions capture the essence of the playing field and lead to the conclusion of how you will win, what capabilities and processes you need to win.
So why not ask more good questions?
