There are so many good ideas in the world; So many booming businesses with excellent performance and products that are changing the world. But, how can we spread these behaviors and products to people in different areas? Or even, just these good practices into other parts of the workplace?
In “Scaling Up Excellence” Sutton and Rao help readers to understand the struggles in sharing replicated practices and behaviors with different people and in different places.
“Scaling is akin to running a long race where you don’t know the right path, often what seems like the right path turns out to be the wrong one, and you don’t know how long the race will last, where or how it will end, or where the finish line is located. Yet it is one of the fundamental challenges that every organization faces, whether it’s small or large, new or old, or somewhere in between.” - Robert I. Sutton & Huggy Rao
They discuss the steps it takes to successfully scaling a company. And, tells you exactly what will hinder the process.
With this information, backed by research, you will be able to tackle your own scaling challenges.
Scaling is the practice of spreading and introducing superb performance to more people and places.
Scaling is often referred to as “the problem of more” because it is a challenge for leaders to spread these positive performances.
The act of scaling can come in many different forms. For example, it could mean opening a new coffee shop in a different city or it could be growing the number of company employees. Or, even improving productivity and lowering mistakes in the workplace.
“It means constantly seeking and implementing better ways of thinking and acting across old and new corners of the system.”- Robert I. Sutton & Huggy Rao
There are two parts to scaling:
These go hand-in-hand. So, the “problem of more” also is the “problem of better” for the leaders in charge.
Scaling requires companies to be innovative by always developing new strategies and organizational structures in the workplace.
There is no easy recipe to follow to successfully scale a workplace to excellence.
When you are working on scaling your company, be prepared to be in it for the long-haul. Scaling takes time, effort, and most of all, persistence.
There will be a lot of unforeseen roadblocks and bumps along the way, but you must have the mental endurance to keep going or else your scaling efforts will fail.
Before you begin, you must have the right amount of resources and manpower to fight through the scaling process.
For example, Mark Zuckerburg, the founder of Facebook made sure that everyone on his team was fully on board with his vision of this new platform.
He made every single employee go through a six-week test that consisted of them working with a mentor and proving that they fully understood the vision of the company.
By spending the time to fully train and…

Scaling Up Excellence is a seminal work co-authored by Robert I. Sutton, a distinguished professor of management science at Stanford University, and Huggy Rao. Sutton’s academic rigor and practical insights into evidence-based management underpin this book, which addresses one of the most pervasive challenges in organizational leadership: how to effectively spread best practices and superior performance across diverse teams and locations. The book’s significance lies in its synthesis of empirical research and real-world case studies, offering a nuanced roadmap for leaders seeking to scale excellence without diluting quality or organizational culture.
The central argument of Scaling Up Excellence is that scaling is fundamentally a complex, iterative process akin to running an uncertain, long-distance race. Success in scaling depends not merely on replication of best practices but also on continuous improvement and adaptation to local contexts. Sutton and Rao emphasize that scaling is simultaneously “the problem of more” and “the problem of better,” requiring leaders to balance standardization with local variation, persist through setbacks, and cultivate the right people and culture to sustain excellence. The authors argue that scaling is less about finding a fixed formula and more about embracing a mindset of persistence, adaptability, and collective responsibility.
Scaling Up Excellence is essential reading for senior executives, organizational development professionals, and entrepreneurs who grapple with the challenges of growth and replication in complex environments. It is particularly valuable for those who appreciate a research-informed yet pragmatic approach to leadership. Additionally, scholars and students of organizational behavior and management will find Sutton and Rao’s synthesis a rich resource for understanding the interplay between culture, strategy, and human dynamics in scaling. However, readers seeking a one-size-fits-all manual or those working in highly specialized or non-commercial sectors may need to supplement this book with more context-specific literature.

Scaling Up Excellence by Robert I. Sutton and Huggy Rao is about the art and science of spreading excellent practices, behaviors, and performance across more people and places in an organization. The book provides research-backed frameworks for leaders facing the "problem of more"—how to grow while maintaining quality, culture, and excellence. It addresses both replicating best practices and improving performance simultaneously as organizations expand.
Scaling Up Excellence is ideal for business leaders, entrepreneurs, managers, and executives who are growing their organizations or expanding into new markets and departments. It's particularly valuable for anyone struggling to maintain excellence and culture during rapid expansion, franchise owners opening new locations, or leaders managing significant increases in team size. The book applies to organizations of any size navigating the complexities of sustainable growth.
The main takeaways include: scaling requires both replicating best practices and improving performance; persistence and adequate resources are essential for success; leaders must balance standardization with local adaptation; the right people and accountability systems are critical; one toxic person can damage team productivity significantly; and deep connections and diversity help spread excellence naturally. Ultimately, Scaling Up Excellence emphasizes that successful growth demands strategic vision, strong team cohesion, and unwavering commitment to maintaining high standards.
Successful scaling requires identifying which core standards and values are non-negotiable across all locations or departments, then allowing flexibility in how those standards are implemented locally. For example, McDonald's maintains consistent operational quality standards globally while adapting menu items to local tastes and preferences. Leaders must consciously decide which practices are universal requirements and which can be customized to respect local cultures and contexts without compromising excellence.
One toxic or underperforming employee can decrease team productivity by 30-40 percent by damaging morale and diverting focus away from work. When organizations scale, they amplify what already exists—both excellence and dysfunction. Removing negative influences before expanding ensures that as the company grows, it spreads excellence rather than spreading negativity, toxicity, or poor practices across the entire expanded organization.
This principle emphasizes that successful scaling focuses on moving large groups forward incrementally and collectively rather than trying to dramatically transform individual performance. Instead of concentrating resources on making one person exceptional, leaders should focus on advancing the entire team's capabilities gradually. This collective approach builds stronger, more cohesive organizations where everyone improves together rather than creating isolated high performers.
Both approaches can work, but leaders must consciously choose which strategy aligns with their organization's culture. Some argue that changing beliefs first drives behavior change, while others find that changing behavior first leads to belief shifts. The key is understanding your organization's dynamics and deliberately selecting whether to motivate through belief or behavior, then executing that chosen strategy consistently throughout the scaling process.
