This book is a great resource for start ups, growth companies and managers. One purpose of this book is to help accelerate transitions that can be so painful and impact both the leaders, the players, the organization and business in many ways.

The author lays out a clear process for these 90 days that moves from getting clear on your strategy, what the leader needs to learn, creating credibility and setting priorities based on the business situation. It looks at how to get everyone on board-including your boss.

The underlying point is that there is logic to organizational alignment. Changing the structure before figuring out the strategy is unlikely to be productive. Also you cannot assess the fitness of your existing crew until you have a handle on your "destination, route, and boat."

One passage talks of Designing Organizational Architecture 
Strategy: The core approach the organization will use to accomplish its goals
Structure: How people are situated in units and how their work is coordinated 
Systems: The processes used to add value
Skills: The capabilities of the various groups of people in the organization
Culture: The values, norms, and assumptions that shape behavior

"Certainly, you need a focused strategy to move forward effectively. But misalignments among any of these five elements can make even the best strategy useless. Strategy drives the other elements"
