The document discusses the challenges of strategy implementation and why it often fails. It notes that leaders are typically trained in strategic planning but not execution. Some of the top reasons for implementation failure include underestimating the challenge, not aligning the organization to take the right actions, and failing to communicate the strategy effectively.
