There are various definitions of strategy, but I will define it as "strategy = winning the competition." In order to win the competition, you need to know the battlefield (the market), know your enemy (the competition), know your own strength (your company), and then formulate an appropriate strategy and start fighting (execute). Theories and methods of strategy support this series of actions. In this lecture, we will cultivate the logical thinking skills that are the basis for "thinking and communicating" in market analysis, planning proposals, and presentations. In addition, while learning the basics of theories and methods in strategy, students will form two groups, one friend and one foe, and acquire "strategic thinking and ideas" through simulated competitive situations.
