This document discusses strategy and its execution using "flight levels" as a framework. It defines three levels - operational, coordination, and strategic. Five activities are outlined for effective strategy execution: visualizing the situation, creating focus, establishing agile interactions, measuring progress, and implementing improvements. Several definitions of strategy are provided. Strategy execution is depicted as an ongoing process of defining work and outcomes, measuring outcomes, refining based on learnings, and ensuring alignment between short, mid, and long-term goals. Common pitfalls like lack of formalization and communication are noted.
