These academic questions that assume all organizations work the same are a waste of your time. For example, the "strategic mindset" needed for an army's battlefield strategy is infinitely different from a marketing strategy at a doughnut shop, coaching a baseball team or a strategy for earning badges in a Boy Scout Troop.
Developing strategy is a combination of both learned and innate traits. It depends on learning the history and makeup of the organization, it's goals, the resources available to achieve them plus the intensity of any competition. That will come easy for a person that's a natural competitor but will be difficult for someone that is innately passive and noncompetitive.
