Why is Strategy important to business growth?
You can read books about strategic planning, about the strategic planning process, or about the benefits of getting alignment on your organization till you're blue in the face.
From a practical application: What if you're part of an organization and things aren't going the way you want them to? How do you bring the issue up with your team?
What if you're the CEO and you aren't sure if the company should continue it's profitable path or look to grow and expand?
What if you're someone on the leadership team with less authoritative power, but you need something to change?
