    Whether it's improving customer experiences, trying out new business models, or developing new products, even the most experienced managers often get it wrong. This is especially true in the online world, where predicting customer behavior is virtually impossible.Managers can, however, discover whether a new product, service, or business model will fail or succeed--by subjecting it to rigorous experimentation. Think about it. A pharmaceutical company would never introduce a new drug without first conducting a round of experiments based on established scientific protocols. Yet that's essentially what many companies do when they roll out new products and services.As Harvard Business School professor Stefan Thomke shows in this eye-opening and essential book, the "best guess" approach to innovation is changing fast. There are now leading companies that conduct more than ten thousand online controlled experiments annually, engaging millions of users. These organizations have discovered that an "experiment with everything" approach has a big payoff, giving them a considerable competitive advantage.How can you do this at your company? Leaders and managers need to create an "experimentation organization" that masters the science of testing and puts the discipline of experimentation at the center of the innovation process. It used to take companies years to build the infrastructure and develop the expertise to run hundreds of experiments each day. But Thomke shows how, with advances in technology, these capabilities are at the fingertips of almost any business professional. By combining the power of software and the rigor of controlled experiments, today's managers can make better decisions, create better customer experiences, and generate huge financial returns.Filled with engaging and instructive stories of leading experimentation organizations, Experimentation Works will be your guidebook to a truly new way of thinking and innovating.

    In my view, there isn't higher praise than that."--Brian Keene, author of The Rising Meet Delphine, Simone, and Zarina. Together they are the Sisters of the Endless Night. For centuries the coven has traveled the width and breadth of the country, unable to call any one place home for very long.

    With profound empathy and meticulous research, Shaili Jain, M.D.—a practicing psychiatrist and PTSD specialist at one of America’s top VA hospitals, trauma scientist at the National Center for PTSD, and a Stanford Professor—shines a long-overdue light on the PTSD epidemic affecting today’s fractured world.Post-Traumatic Stress Disorder goes far beyond the horrors of war and is an inescapable part of all our lives. At any given moment, more than six million Americans are suffering with PTSD. Dr. Jain’s groundbreaking work demonstrates the ways this disorder cuts to the heart of life, interfering with one’s capacity to love, create, and work—incapacity brought on by a complex interplay between biology, genetics, and environment. Beyond the struggles of individuals, PTSD has a tangible imprint on our cultures and societies around the world.Since 9/11 and the wars in Iraq and Afghanistan, there has been a huge growth in the science of PTSD, a body of evidence that continues to grow exponentially. With this new knowledge have come dramatic advances in the effective treatment of this condition. Jain draws on a decade of her own clinical innovation and research and argues for a paradigm shift in how PTSD should be approached in the new millennium. She highlights the myriads of ways PTSD care is being transformed to make it more accessible, acceptable, and available to sufferers via integrated care models, use of peer support programs, and technology. By identifying those among us who are most vulnerable to developing PTSD, cutting edge medical interventions that hold the promise of preventing the onset of PTSD are becoming more of a reality than ever before.Combining vividly recounted patient stories, interviews with some of the world’s top trauma scientists, and her professional expertise from working on the frontlines of PTSD, The Unspeakable Mind offers a textured portrait of this invisible illness that is unrivaled in scope and lays bare PTSD's roots, inner workings, and paths to healing. This book is essential reading for understanding how humans can recover from unspeakable trauma. The Unspeakable Mind stands as the definitive guide to PTSD and offers lasting hope to sufferers, their loved ones, and health care providers everywhere.
