The document discusses five factors that contributed to flattening the world as described in Thomas Friedman's book "The World Is Flat": 1) The fall of the Berlin Wall in 1989 which opened up Europe. 2) The release of the Netscape web browser in 1994 which helped drive the commercialization of the internet. 3) Workflow software which helps manage business processes. 4) Open source software which allows software code to be shared and built upon publicly. 5) Supply chain networks which connect retailers, suppliers and partners globally.
