资料：Keeping the Zeal of a Startup as You Scale
There are many reasons that founder-led companies are so good at disrupting industries and making life miserable for slow-moving incumbents. But perhaps the most powerful is that founders create great insurgencies. They ignore established industry rules and boundaries. They create better ways to solve old problems. They disdain anything that blurs their focus on the front line. From top to bottom, they are at war against the industry leaders on behalf of undeserved customers.
Our research on what we call the “founder’s mentality” shows that maintaining a strong insurgent mission is critical to long-term, sustainable growth. But to compete long term, insurgent companies also need to develop scale and scope, which very often dulls their insurgent’s zeal. In many ways, this is because their perspective on the future slowly changes. Insurgents see the days ahead—both long and short term—as ripe with opportunity. They embrace change and chaos. They invest in whatever it takes to innovate new solutions for customers. Incumbents, on the other hand, very often see the future as a threat. As leaders invested heavily in the status quo, innovation and disruption are not good for them. Turbulence erodes profitability; innovation marginalizes their current product offerings. The future is not better.
The companies that find a way to achieve scale without losing their insurgent mission---we call them “Scale Insurgents”--remain acutely alert to this difference in perspective. They actively fight back against the very natural tendency to retreat behind the castle walls to avoid future change and turbulence. Instead, they do what in some companies might seem like heresy---they commit to disrupting their own insurgency. They know that acquiring the benefits of scale requires ruthless focus on a well-defined core business and a commitment to building the systems and processes to support it. But they aren’t wedded to their business model—they are wedded to what will serve their customers best. Rather than erecting defenses against the future, they embrace the notion of limitless horizons—the idea that a company can intelligently extend the boundaries of its core ever outward.

B.An insurgent company prefers chaos to stability
C.An insurgent company loves challenging the incumbent companies

Book Review of Anne Narazaki's
New Century, New Business
Reviewed by John Gilliam
Anne Narazaki's recent book, New Century, New Business, seeks to examine the new tech-nologies that are critical for global business and how they affect today's corporate transactions. Ms.Narazaki argues that while economic transactions of one kind or another have taken place for thou-sands of years, the impact of changing technology on business has become obvious only recently. In　fact, as new technologies have grown more prevalent, Ms. Narazaki observes, international busi-nesses have increased in size and number. At the same time, the time required to conduct each　business transaction has decreased.
Mr. Narazaki illustrates her observations with detailed examples of recent business transac-tions. Citing the merger of Poynter Technologies and Carce Company, which created the largest fi-nancial services company in the world, Ms. Narazaki explains the effect technology has on the val-uation of a company, on communication between the managements of different companies, and on　stock and funds trading.
Those of us who take an interest in the interaction between business and technology will find　Ms. Narazaki's ideas persuasive. The view that business cannot survive without keep~ing up with　new technology has become today's corporate reality.
