This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience.

    Gerard, PhD, its chief learning officer, candidly describe the triumphs and stumbles of a seven-year journey to lean healthcare, an effort that continues today and that has slashed medical errors, improved patient outcomes, raised staff morale, and saved $27 million dollars in costs without layoffs. Find out:> How lean techniques of value-stream-mapping and rapid improvement events cut the average “door-to-balloon” time for heart attack patients at two hospitals from 90 minutes to 37.> What ThedaCare leaders did to replace medicine’s “shame and blame” culture with a lean culture based on continuous improvement and respect for people.> How the lean principle of “building in quality at the source” broke down divisions among medical specialties allowing teams to develop patient care plans faster.> Why traditional modern management is the single biggest impediment to lean healthcare.> How the plan-do-study-act cycle coupled with rapid improvement events cut the wait time at a robotic radiosurgery unit from 26 days to six.> How the lean concept of “one piece flow” saved time in treating ischemic stroke patients, increasing the number of patients receiving a CT scan within 25 minutes from 51% to 89%.> How senior leaders at other healthcare organizations can begin their own lean transformations using a nine-step action plan based on what ThedaCare did — and what it would do differently.Toussaint and Gerard prove that lean healthcare does not mean less care. On the Mend shows that when care is truly re-designed around patients, waste and errors are eliminated, quality improves, costs come down, and healthcare professionals have more time to spend with patients, who get even better care.

    Kai-Fu Lee—one of the world’s most respected experts on AI and China—reveals that China has suddenly caught up to the US at an astonishingly rapid and unexpected pace.In AI Superpowers, Kai-Fu Lee argues powerfully that because of these unprecedented developments in AI, dramatic changes will be happening much sooner than many of us expected. Indeed, as the US-Sino AI competition begins to heat up, Lee urges the US and China to both accept and to embrace the great responsibilities that come with significant technological power.Most experts already say that AI will have a devastating impact on blue-collar jobs. But Lee predicts that Chinese and American AI will have a strong impact on white-collar jobs as well. Is universal basic income the solution? In Lee’s opinion, probably not.  But he provides a clear description of which jobs will be affected and how soon, which jobs can be enhanced with AI, and most importantly, how we can provide solutions to some of the most profound changes in human history that are coming soon.

    Porter's Competitive Advantage explores the underpinnings of competitive advantage in the individual firm.Competitive Advantage introduces a whole new way of understanding what a firm does. Porter's groundbreaking concept of the value chain disaggregates a company into "activities," or the discrete functions or processes that represent the elemental building blocks of competitive advantage. Now an essential part of international business thinking, Competitive Advantage takes strategy from broad vision to an internally consistent configuration of activities. Its powerful framework provides the tools to understand the drivers of cost and a company's relative cost position. Porter's value chain enables managers to isolate the underlying sources of buyer value that will command a premium price, and the reasons why one product or service substitutes for another. He shows how competitive advantage lies not only in activities themselves but in the way activities relate to each other, to supplier activities, and to customer activities. Competitive Advantage also provides for the first time the tools to strategically segment an industry and rigorously assess the competitive logic of diversification. That the phrases "competitive advantage" and "sustainable competitive advantage" have become commonplace is testimony to the power of Porter's ideas. Competitive Advantage has guided countless companies, business school students, and scholars in understanding the roots of competition. Porter's work captures the extraordinary complexity of competition in a way that makes strategy both concrete and actionable.

    Digital technologies—with hardware, software, and networks at their core—will in the near future diagnose diseases more accurately than doctors can, apply enormous data sets to transform retailing, and accomplish many tasks once considered uniquely human.In The Second Machine Age MIT’s Erik Brynjolfsson and Andrew McAfee—two thinkers at the forefront of their field—reveal the forces driving the reinvention of our lives and our economy. As the full impact of digital technologies is felt, we will realize immense bounty in the form of dazzling personal technology, advanced infrastructure, and near-boundless access to the cultural items that enrich our lives.Amid this bounty will also be wrenching change. Professions of all kinds—from lawyers to truck drivers—will be forever upended. Companies will be forced to transform or die. Recent economic indicators reflect this shift: fewer people are working, and wages are falling even as productivity and profits soar.Drawing on years of research and up-to-the-minute trends, Brynjolfsson and McAfee identify the best strategies for survival and offer a new path to prosperity. These include revamping education so that it prepares people for the next economy instead of the last one, designing new collaborations that pair brute processing power with human ingenuity, and embracing policies that make sense in a radically transformed landscape.A fundamentally optimistic book, The Second Machine Age alters how we think about issues of technological, societal, and economic progress.
