Before you start developing your BSC, you need to have a clear and shared understanding of your organization's strategy and vision. Your strategy is the plan of action that guides your decisions and actions to achieve your desired outcomes. Your vision is the long-term aspiration that inspires and motivates your organization. You can use tools such as SWOT analysis, PEST analysis, Porter's five forces, or value proposition canvas to identify your strengths, weaknesses, opportunities, threats, external factors, competitive advantages, and customer needs. You can also use tools such as vision statement, mission statement, or strategic themes to articulate your strategy and vision in a concise and compelling way.
