"Vertigo--that dizzy, confused state of mind where your surroundings whirl about you--is disastrous for pilots who suffer disorientation and lose control of their aircraft," says Harvard Business School professor Richard Nolan, "and it is no less catastrophic for businesses and their investors who are now plunging headlong into an increasingly unpredictable economic landscape." In Dot Vertigo, Nolan proposes an antidote based on the way leading bricks-and-mortar firms and Web companies (including IBM, Merrill Lynch, drugstore.com, and Amazon.com) are successfully using the technological advances causing this frenetic confusion among others to meet the challenges of the new "permeable" or less rigid corporate world. The core of the solution is something he dubs the I-Net, which is sort of a combined Internet-Intranet that thoroughly and seamlessly integrates all internal and external functions of a given company.

The first part of the book examines this vertigo or business disorientation and relates it to the need for permeability that Nolan marks as key to future success. The second completely outlines the I-Net infrastructure, including financial benchmarks and metrics necessary for building one that is fully attuned to a company's specific financial and operational realities. The third draws upon Nolan's extensive case studies of the above-mentioned firms and others to show how successful planning and implementation can be achieved. One of a growing wave of management books to reach beyond the technomarket meltdown for associated best practices that remain viable for spurring long-term strategic improvement, this will be welcomed by anyone who recognizes that technology is not the total solution but rather one critical piece of an evolving puzzle whose impacts (both good and bad) are here to stay. --Howard Rothman Harvard Business School's leading technology expert reveals a bold new concept: the permeable-and highly profitable-business Richard Nolan is one of the most influential voices in Silicon Valley today. A Harvard Business School professor and an advisor to business leaders such as Cisco and Charles Schwab, Nolan's reputation as a thought leader in high-tech is unparalleled. In Dot Vertigo, Professor Nolan explores the ways in which both blue chip brick-and-mortar and first-generation Web companies are responding to an onslaught of new competitors; and how, in some cases, they have adapted to meet these competitors head-on. Introducing the concept of "permeability," as the number-one indicator of long-term growth and profitability, Nolan shows why it is so important for a company to make the transformation into a completely networked organization. Nolan warns that the first sign of serious trouble is "dot vertigo," when companies, like pilots, lose sight of their reference points and can't adapt to a changing landscape. Nolan illustrates how to beat dot vertigo by building a permeable business using the I-Net-the next generation of the Internet in which an organization's intranet is seamlessly merged with the Internet.
