How Information Gives
You Competitive Advantage
Michael E. Porter and Victor E. Millar


he information revolution is sweeping
through our economy. No company can escape its effects. Dramatic reductions in thecost of obtaining, processing, and transmitting information are changing the way we do business.
Most general managers know that the revolution is
under way, and few dispute its importance. As
more and more of their time and investment capital is absorbed in information technology and its
effects, executives have a growing awareness that
the technology can no longer be the exclusive territoryof EDP or IS departments. As they see their rivals
use information for competitive advantage, these executives recognize the need to become directly involved in the management of the new technology. In
the face of rapid change, however, they don’t know
This article aims to help general managers respond
to the challenges of the information revolution. How
will advances in informationtechnology affect competition and the sources of competitive advantage?
What strategies should a company pursue to exploit
the technology? What are the implications of actions
that competitors may already have taken? Of the
many opportunities for investment in information
technology, which are the most urgent?
To answer these questions, managers must first
understand that informationtechnology is more than

It creates competitive advantage by giving companies new ways to outperform their rivals.
It spawns whole new businesses,often from
within a company’s existing operations.
We discuss the reasons why information technology has acquired strategic significance and how it is
affecting all businesses. We then describe how the
new technology changes the nature of competition
and how astute companies have exploited this. Finally, we outline a procedure managers can use to
assess the role of information technology intheir
business and to help define investment priorities to
turn the technology to their competitive advantage.

Information technology is changing the way companies operate. It is affecting the entire process by
which companies create their products. Furthermore,

of physical goods, services, and information...
