In a pathbreaking 1989 essay, “Computer and Dynamo: The Modern Productivity Paradox in a Not-Too Distant Mirror,” the economic historian Paul A. David explained such a lag by pointing to a historical precedent. He noted that while the lightbulb was invented in 1879, it took several decades for electrification to kick in and have a big economic and productivity impact. Why? Because it was not enough just to install electric motors and scrap the old technology-steam engines. The whole way of doing manufacturing had to be reconfigured. In the case of electricity, David pointed out, the key breakthrough was in how buildings, and assembly lines, were redesigned and managed. Factories in the steam age tended to be heavy, costly multistory buildings designed to brace the weighty belts and other big transmission devices needed to drive steam-powered systems. Once small, powerful electric motors were introduced, everyone hoped for a quick productivity boost. It took time, though. To get all the savings, you needed to redesign enough buildings. You needed to have long, low, cheaper-to-build single-story factories, with small electric motors powering machines of all sizes. Only when there was a critical mass of experienced factory architects and electrical engineers and managers, who understood the complementarities among the electric motor, the redesign of the factory, and the redesign of the production line, did electrification really deliver the productivity breakthrough in manufacturing, David wrote.
The same thing is happening today with the flattening of the world. Many of the ten flatteners have been around for years. But for the full flattening effects to be felt, we needed not only the ten flatteners to converge but also something else. We needed the emergence of a large cadre of managers, innovators, business consultants, business schools, designers, IT specialists, CEOs, and workers to get comfortable with, and develop, the sorts of horizontal collaboration and value-creation processes and habits that could take advantage of this new, flatter playing field. In short, the convergence of the ten flatteners begat the convergence of a set of business practices and skills that would get the most out of the flat world. And then the two began to mutually reinforce each other.
“When people asked, 'Why didn't the IT revolution lead to more productivity right away?' it was because you needed more than just new computers,” said Romer. “You needed new business processes and new types of skills to go with them. The new way of doing things makes the information technologies more valuable, and the new and better information technologies make the new ways of doing things more possible.”
Globalization 2.0 was really the era of mainframe computing, which was very vertical-command-and-control oriented, with companies and their individual departments tending to be organized in vertical silos. Globalization 3.0, which is built around the convergence of the ten flatteners, and particularly the combination of the PC, the microprocessor, the Internet, and fiber optics, flipped the playing field from largely top-down to more side to side. And this naturally fostered and demanded new business practices, which were less about command and control and more about connecting and collaborating horizontally.
“We have gone from a vertical chain of command for value creation to a much more horizontal chain of command for value creation,” explained Carly Fiorina. Innovations in companies like HP, she said, now come more and more often from horizontal collaboration among different departments and teams spread all across the globe. For instance, HP, Cisco, and Nokia recently collaborated on the development of a camera/ cell phone that beams its digitized pictures to an HP printer, which quickly prints them out. Each company had developed a very sophisticated technological specialty, but it could add value only when its specialty was horizontally combined with the specialties of the other two companies.
“How you collaborate horizontally and manage horizontally requires a totally different set of skills” from traditional top-down approaches, Fiorina added.
Let me offer just a few examples. In the past five years, HP has gone from a company that had eighty-seven different supply chains-each managed vertically and independently, with its own hierarchy of managers and back-office support-to a company with just five supply chains that manage $50 billion in business, and where functions like accounting, billing, and human resources are handled through a companywide system.
