Friedman defines ten "flatteners" that he sees as leveling the global playing field:

• #1: Collapse of Berlin Wall--11/'89: The event not only symbolized the end of the Cold war, it allowed people from other side of the wall to join the economic mainstream. (11/09/1989)
• #2: Netscape: Netscape and the Web broadened the audience for the Internet from its roots as a communications medium used primarily by 'early adopters and geeks' to something that made the Internet accessible to everyone from five-year-olds to ninety-five-year olds. (8/9/1995). The digitization that took place meant that everyday occurrences such as words, files, films, music and pictures could be accessed and manipulated on a computer screen by all people across the world.
• #3: Workflow software: The ability of machines to talk to other machines with no humans involved. Friedman believes these first three forces have become a “crude foundation of a whole new global platform for collaboration.”
• #4: Open sourcing: Communities uploading and collaborating on online projects. Examples include open source software, blogs, and Wikipedia. Friedman considers the phenomenon "the most disruptive force of all."
• #5: Outsourcing: Friedman argues that outsourcing has allowed companies to split service and manufacturing activities into components which can be subcontracted and performed in the most efficient, cost-effective way.
• #6: Offshoring: The internal relocation of a company's manufacturing or other processes to a foreign land in order to take advantage of less costly operations there.
• #7: Supply chaining: Friedman compares the modern retail supply chain to a river, and points to Wal-Mart as the best example of a company using technology to streamline item sales, distribution, and shipping.
• #8: Insourcing: Friedman uses UPS as a prime example for insourcing, in which the company's employees perform services--beyond shipping--for another company. For example, UPS repairs Toshiba computers on behalf of Toshiba. The work is done at the UPS hub, by UPS employees.
• #9: In-forming: Google and other search engines are the prime example. "Never before in the history of the planet have so many people-on their own-had the ability to find so much information about so many things and about so many other people", writes Friedman. The growth of search engines is tremendous; for example take Google, in which Friedman states that it is "now processing roughly one billion searches per day, up from 150 million just three years ago".
• #10: "The Steroids": Personal digital devices like mobile phones, iPods, personal digital assistants, instant messaging, and voice over Internet Protocol (VoIP).
