Quite soon, the world's information infrastructure is going to reach a level of scale and complexity that will force scientists and engineers to approach it in an entirely new way. The familiar notions of command and control are being thwarted by realities of a faster, denser world of communication where choice, variety, and indeterminism rule. The myth of the machine that does exactly what we tell it has come to an end. What makes us think we can rely on all this technology? What keeps it together today, and how might it work tomorrow? Will we know how to build the next generation-or will we be lulled into a stupor of dependence brought about by its conveniences? In this book, Mark Burgess focuses on the impact of computers and information on our modern infrastructure by taking you from the roots of science to the principles behind system operation and design. To shape the future of technology, we need to understand how it works-or else what we don't understand will end up shaping us. This book explores this subject in three parts: Part I, Stability: describes the fundamentals of predictability, and why we have to give up the idea of control in its classical meaning Part II, Certainty: describes the science of what we can know, when we don't control everything, and how we make the best of life with only imperfect information Part III, Promises: explains how the concepts of stability and certainty may be combined to approach information infrastructure as a new kind of virtual material, restoring a continuity to human-computer systems so that society can rely on them.

What people are saying about The New How "How are you going to get rid of your Air Sandwich if you don't even know what it is? Provocative and practical at the same time." --Seth Godin, author of Linchpin "The New How is informative and provides exciting insights because the suggestions are practical and doable. Merchant gets the new reality--leadership fails not so much from flawed strategy as it does from failed processes of engagement from those responsible for implementing the strategy. In high-performing organizations, everyone acts like a leader, and they own the strategy and take actions to ensure its success. If you care about making a difference, read this book." --Barry Posner, author of The Leadership Challenge "Collaboration is a powerful, competitive weapon: this book shows you how to use it to win markets." --Mark Interrante, VP Content Products, Yahoo, Inc. "In a world in which the pace of change is ever quickening, collaboration, not control, is the route to a successful organization. This book tells you how to make your organization collaborative. And Nilofer Merchant's writing is a model of clarity." --Barry Schwartz, author of The Paradox of Choice: Why More Is Less "Want to transform your organization into a collaborative enterprise? Nilofer Merchant provides insightful and practical strategies in The New How." --Padmasree Warrior, CTO, Cisco Systems, Inc. "Merchant's book is a practical guide for the journey from strategy to implementation. The collaborative tools described here can help companies reach strategic success--and avoid pitfalls along the way." --Tom Kelley, General Manager, IDEO, and author of Ten Faces of Innovation Once in a generation, a book comes along that transforms the business landscape. For today's business leaders, The New How redefines the way companies create strategies and win new markets. Management gurus have always said "people matter." But those same gurus still relegate strategy to an elite set of executives who focus on frameworks, long presentations, and hierarchical approaches. Business strategy typically has been planned by corporate chiefs in annual meetings, and then dictated to managers to carry out. The New How turns that notion on its head. After many years of working with Apple, Adobe, HP, and many other companies, Nilofer Merchant discovered the secret sauce: the best way to create a winning strategy is to include employees at all levels, helping to create strategy they not only believe in, but are also equipped to implement. In The New How, Nilofer shows today's corporate directors, executives, and managers how they can transform their traditional, top-down approach to strategy planning and execution into collaborative "stratecution" that has proven to be significantly more effective. Enhance performance and outcomes by deflating the "air sandwich" between executives in the boardroom and employees Recognize that strategy and execution are thoroughly intertwined Understand how successful strategy is founded in effective idea selection-a pile of good ideas doesn't necessarily build good strategy Create company strategy and link it to targeted execution, using the practical models and techniques provided
