Strategy is a plan of action designed to achieve a long-term goal or aim. It is an art of planning operations and movements involving tactics. It is not a plan, and the goal is not the strategy, strategy is how we achieve the goal. It is allocation of resources, organisational design, portfolio management and trade-offs. These operate on 3 levels: corporate, business and functional. Each flow to the next, are interdependent, this why communication between all levels is critical for effective leadership. Strategy improves decision making as the vison and direction are clear.
