The cellular structure of any truly great organization is the well-led unit, for this is where great things get done. Great leadership at the top doesn’t amount to very much without exceptional leadership at the unit level. If you want to build a truly great company or social-sector enterprise, you need to cultivate legions of unit leaders who, in turn, create unit cohesion in pursuit of audacious objectives. If you want to scale your culture, if you want to make the journey from great company to enduring great company, you must invest in building a pipeline of the right unit leaders.

Leadership is a quality rather than a job. We are all leaders and followers at different points in our lives. Many aspects of this book should be useful to those looking to grow as leaders as well as managers, and great managers should cultivate leadership not just in themselves but also within their teams.

This is an important distinction because while the role of a manager can be given to someone (or taken away), leadership is not something that can be bestowed. It must be earned. People must want to follow you.

Rather than attempting to acquire your way into a more attractive position, you can set a better goal for your company. The real goal should be to create an internal discipline of strategic thinking that enables a more thoughtful approach to the current game, regardless of industry, and connects to possible different futures and opportunities.

The goal was to create a culture of inquiry that would surface productive tensions to inform smarter choices. The explicit goal was to create strategists at all levels of the organization. Over the course of a career, P&G leaders gain practice designing strategy for brands and products lines, categories, channels, customer relationships, countries and regions, and functions and technologies. The idea is to build up strategy muscles over time, in different contexts, so that as managers rise in the organization, they are well prepared for the next strategic task.

Culture isn’t just one aspect of the game - it is the game,” Gerstner says. “In the end, an organization is nothing more than the collective capacity of its people to create value. Vision, strategy, marketing, financial management - any management system, in fact - can set you on the right path and can carry you for a while. But no enterprise - whether in business, government, education, health care, or any area of human endeavor - will succeed over the long haul if those elements aren’t parts of its DNA.”

Chris Lofgren, chief executive of Schneider National, the large transportation and logistics company believes that “culture is a foundation upon which you build your long-term strategy. If you build a strategy that isn’t consistent with the culture, it isn’t going to work.
