Good strategy is characterized by clarity and impact because it provides a clear direction and outlines how actions will lead to desired outcomes. A clear strategy is easy to understand and communicate, ensuring everyone is aligned. An impactful strategy focuses on actions that will genuinely move the needle towards objectives. "Big numbers" alone don't define good strategy; they might be goals, but not the strategic approach itself. "Lots of details" can be overwhelming and obscure the core strategic direction, making it difficult to execute effectively. While details are important for implementation, the strategy itself should be concise and focused on the 'what' and 'why,' not exhaustive 'how-to' specifics.
