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.

But there’s also a hopeful story to tell. Companies can sustain greatness for decades, even if only a few do so. What this means is that you never get to the “end” of The Map. You’re never done with the journey. You’re never done with the need for disciplined people who engage in disciplined thought and take disciplined action. You’re never done renewing the company so that it might be built to last. You’re never done preparing for bad luck and capitalizing on good luck, getting a higher return on luck than others. Greatness is an inherently dynamic process, not an end point.

The Map doesn’t guarantee a great outcome. But those who adhere to its principles—and who do so with joyful intensity—have much better odds of building a great company that can endure than those who don’t. Along the way, perhaps as more of a by-product than a goal, they just might find the daily happiness that comes from doing meaningful work with people they truly like and deeply respect. And it’s hard to have a better life than that.

Your company is a maximization machine—it wants to make the best use of its finite resources—so it is greatly interested in identifying precisely who to invest in, and how.

The problem with this stems from the way your company executes on these good intentions. Why, for example, does it assume that it will net a good return only from certain people? Surely, the cliché that “Our people are our greatest asset” applies to all of the people in the company. As we’ve seen, every human brain retains its ability to learn and grow throughout adulthood. For sure, each brain grows at a different speed and in a different way, but this implies only that each person learns differently, not that—categorically—some people do and some don’t. Therefore, the best course of action for any maximization machine worth its salt would be to figure out where and how each brain can grow the most, rather than zeroing in on only a select few brains and casting aside the others.

But more often the real shock of growth is that over time you’ll bring on people who are just okay. Relative to the amazing people you brought in early, they’ll seem unimpressive. Mostly fine, good team players, get the job done.

And that’s not the end of the world. As the company expands, you need all kinds of people at all kinds of levels.

You can’t wait for the perfect A+ candidate to appear for every single empty slot. You need to hire. The best of the best don’t always want to join a big team, or they’re tied up in another job, or you can’t afford them or give them the titles or responsibilities they want.

And sometimes the people you don’t expect to be amazing—the ones you thought were Bs and B+s—turn out to completely rock your world. They hold your team together by being dependable and flexible and great mentors and teammates. They’re modest and kind and just quietly do good work. They’re a different type of “rock star.”

By far the hardest part of growth is finding the best people—in all their different incarnations—trusting your team to hire them, then making sure they’re happy and thriving.

In summary, growing a business is a dynamic process as the leadership team navigates the evolutions and revolutions of growth. And like the growth stages of a child, they are predictable and unavoidable. To deal with these challenges, the company must grow the capabilities of the leadership team throughout the organization; install scalable infrastructure to manage the increasing complexities that come with growth; and stay on top of the

market dynamics that affect the business.

To do this, there are 4 Decisions that leaders must address: People, Strategy,

Execution, and Cash.
