Loonshots by Safi Bahcall

KShs3,000.00 KShs2,890.00
Loonshots: How to Nurture the Crazy Ideas That Win Wars, Cure Diseases, and Transform Industries. Why do good teams kill great ideas? Loonshots reveals a surprising new way of thinking about the mysteries of group behavior that challenges everything we thought we knew about nurturing radical breakthroughs. Bahcall, a physicist and entrepreneur, shows why teams, companies, or any group with a mission will suddenly change from embracing new ideas to rejecting them, just as flowing water will suddenly change into brittle ice. Mountains of print have been written about culture. Loonshots identifies the small shifts in structure that control this transition, the same way that temperature controls the change from water to ice. Using examples that range from the spread of fires in forests to the hunt for terrorists online, and stories of thieves and geniuses and kings, Bahcall shows how a new kind of science can help us become the initiators, rather than the victims, of innovative surprise. Over the past decade, researchers have been applying the tools and techniques of this new science? the science of phase transitions?to understand how birds flock, fish swim, brains work, people vote, diseases erupt, and ecosystems collapse. Loonshots is the first to apply this science to the spread of breakthrough ideas. Bahcall distills these insights into practical lessons creatives, entrepreneurs, and visionaries can use to change our world. Along the way, readers will learn how chickens saved millions of lives, what James Bond and Lipitor have in common, what the movie Imitation Game got wrong about WWII, and what really killed Pan Am, Polaroid, and the Qing Dynasty.  

The Partnership The Making of Goldman...

KShs3,000.00 KShs2,700.00
Despite financial turmoil, Goldman Sachs remain the leading investment bank in their field. They are notorious for their unique management culture, unorthodox recruiting techniques - and for their secrecy. In The Partnership Charles Ellis reveals their story. With unparalleled access to the leadership of this famously close-knit firm, Ellis investigates the brilliant individuals who turned a marginal family business into a global powerhouse, weathering recession, scandal and disaster on the way. Among them are high school dropout and financial genius Sidney Weinberg, maverick reinventor John Whitehead, former US treasury secretary Hank Paulson and working-class New Yorker turned current CEO, Lloyd Blankfein. The Partnership reveals the shared values of intensive recruitment, discipline and talent that have tied Goldman Sachs's people together - and made it a survivor.

When Genius Failed by Roger Lowenstein

KShs1,499.00 KShs1,425.00
Brief Summary When Genius Failed: The Rise and Fall of Long-Term Capital Management. In this business classic—now with a new Afterword in which the author draws parallels to the recent financial crisis—Roger Lowenstein captures the gripping roller-coaster ride of Long-Term Capital Management. Drawing on confidential internal memos and interviews with dozens of key players, Lowenstein explains not just how the fund made and lost its money but also how the personalities of Long-Term’s partners, the arrogance of their mathematical certainties, and the culture of Wall Street itself contributed to both their rise and their fall. When it was founded in 1993, Long-Term was hailed as the most impressive hedge fund in history. But after four years in which the firm dazzled Wall Street as a $100 billion moneymaking juggernaut, it suddenly suffered catastrophic losses that jeopardized not only the biggest banks on Wall Street but the stability of the financial system itself. The dramatic story of Long-Term’s fall is now a chilling harbinger of the crisis that would strike all of Wall Street, from Lehman Brothers to AIG, a decade later. In his new Afterword, Lowenstein shows that LTCM’s implosion should be seen not as a one-off drama but as a template for market meltdowns in an age of instability—and as a wake-up call that Wall Street and government alike tragically ignored.

Rogue Trader by Nick Leeson

KShs1,499.00 KShs1,425.00
Brief Summary When Leeson was arrested in 1995 for bringing Barings Bank to its knees, it initially seemed as if he had single-handedly crushed the company. Indeed, it was he alone who found himself in the dark confines of a Singapore jail, from where he wrote Rogue Trader. Now updated for the twentieth anniversary of the collapse of Barings, this is his story of a broken system; of a cast of characters blind to anything but profits - whatever the cost. Leeson's tale of boom and bust is an important reminder of the immense power the banking system held and, worryingly, still holds. ISBN:9780751563399 Author:Nick Leeson

Lights Out : Pride, Delusion, and the...

KShs3,990.00 KShs3,490.00
How could General Electric—perhaps America’s most iconic corporation—suffer such a swift and sudden fall from grace? This is the definitive history of General Electric’s epic decline, as told by the two Wall Street Journal reporters who covered its fall. Since its founding in 1892, GE has been more than just a corporation. For generations, it was job security, a solidly safe investment, and an elite business education for top managers. GE electrified America, powering everything from lightbulbs to turbines, and became fully integrated into the American societal mindset as few companies ever had. And after two decades of leadership under legendary CEO Jack Welch, GE entered the twenty-first century as America’s most valuable corporation. Yet, fewer than two decades later, the GE of old was gone. ?Lights Out examines how Welch’s handpicked successor, Jeff Immelt, tried to fix flaws in Welch’s profit machine, while stumbling headlong into mistakes of his own. In the end, GE’s traditional win-at-all-costs driven culture seemed to lose its direction, which ultimately caused the company’s decline on both a personal and organizational scale. Lights Out details how one of America’s all-time great companies has been reduced to a cautionary tale for our times. ISBN:9780358250418 Author:Ted Mann and Thomas Gryta

Kleptopia How Dirty Money Is Conqueri...

KShs2,799.00 KShs1,799.00
"A must-read for anyone wanting to better understand what has already happened here in America and what lies ahead if Trump is reelected in November…. A magisterial account of the money and violence behind the world’s most powerful dictatorships.” –Washington Post In this shocking, meticulously reported work of narrative nonfiction, an award-winning investigative journalist exposes "capitalism’s monster”—global kleptocracy—and reveals how it is corrupting the world around us. They are everywhere, the thieves and their people. Masters of secrecy. Until now we have detected their presence only by what they leave behind. A body in a burned-out Audi. Workers riddled with bullets in the Kazakh Desert. A rigged election in Zimbabwe. A British banker silenced and humiliated for trying to expose the truth about the City of London. They have amassed more money than most countries. But what they are really stealing is power. In this real-life thriller packed with jaw-dropping revelations, award-winning investigative journalist Tom Burgis weaves together four stories that reveal a terrifying global web of corruption: the troublemaker from Basingstoke who stumbles on the secrets of a Swiss bank, the ex-Soviet billionaire constructing a private empire, the righteous Canadian lawyer with a mysterious client, and the Brooklyn crook protected by the CIA. Glimpses of this shadowy world have emerged over the years. In Kleptopia, Burgis connects the dots. He follows the dirty money that is flooding the global economy, emboldening dictators, and poisoning democracies. From the Kremlin to Beijing, Harare to Riyadh, Paris to the White House, the trail shows something even more sinister: the thieves are uniting. And the human cost will be great.

Contagious by Jonah Berger

KShs2,000.00 KShs1,790.00
Brief Summary Contagious: Why Things Catch On. What makes things popular? Why do people talk about certain products and ideas more than others? Why are some stories and rumors more infectious? And what makes online content go viral? If you said advertising, think again. People don't listen to advertisements, they listen to their peers. But why do people talk about certain products and ideas more than others? Why are some stories and rumors more infectious? And what makes online content go viral? Wharton marketing professor Jonah Berger has spent the last decade answering these questions. He's studied why New York Times articles make the paper's own Most E-mailed List, why products get word of mouth, and how social influence shapes everything from the cars we buy to the clothes we wear to the names we give our children. In this book, Berger reveals the secret science behind word-of-mouth and social transmission. Discover how six basic principles drive all sorts of things to become contagious, from consumer products and policy initiatives to workplace rumors and YouTube videos. Contagious combines groundbreaking research with powerful stories. Learn how a luxury steakhouse found popularity through the lowly cheese-steak, why anti-drug commercials might have actually increased drug use, and why more than 200 million consumers shared a video about one of the seemingly most boring products there is: a blender. If you've wondered why certain stories get shared, e-mails get forwarded, or videos go viral, Contagious explains why, and shows how to leverage these concepts to craft contagious content. This book provides a set of specific, actionable techniques for helping information spread - for designing messages, advertisements, and information that people will share. Whether you're a manager at a big company, a small business owner trying to boost awareness, a politician running for office, or a health official trying to get the word out, Contagious will show you how to make your product or idea catch on.

Whether at work, in relationships, or in shaping the world around you, The Laws of Human Nature offers brilliant tactics for success, self-improvement, and self-defense.

Extreme Economies by Richard Davies

KShs2,799.00 KShs2,190.00
Brief Summary To understand how humans react and adapt to economic change we need to study people who live in harsh environments. From war zones, natural disasters and failed states, to aging societies and the challenges of technological advancement, every life in this book has been hit by a seismic shock, violently broken or changed in some way. People living in these odd and marginal places are ignored by number crunching economists and political pollsters alike. Science suggests this is a mistake. This book tells the personal stories of humans living in extreme situations, and of the financial infrastructure they create. Here, economies are not concerned with the familiar stock market crashes, housing crises, or banking scandals of the financial pages. In his quest for a purer view of how economies succeed and fail, Richard Davies takes the reader off the beaten path to places where part of the economy has been repressed, removed, destroyed or turbocharged. By travelling to each of them and discovering what life is really like, Extreme Economies tells small stories that shed light on today’s biggest economic questions, with vital lessons for our future.

The Founders Mentality by Chris Zook ...

KShs3,699.00 KShs3,515.00
Brief Summary The Founder’s Mentality: How to Overcome the Predictable Crises of Growth. Three Principles for Managing—and Avoiding—the Problems of Growth Why is profitable growth so hard to achieve and sustain? Most executives manage their companies as if the solution to that problem lies in the external environment: find an attractive market, formulate the right strategy, win new customers. But when Bain & Company’s Chris Zook and James Allen, authors of the bestselling Profit from the Core, researched this question, they found that when companies fail to achieve their growth targets, 90 percent of the time the root causes are internal, not external—increasing distance from the front lines, loss of accountability, proliferating processes and bureaucracy, to name only a few. What’s more, companies experience a set of predictable internal crises, at predictable stages, as they grow. Even for healthy companies, these crises, if not managed properly, stifle the ability to grow further—and can actively lead to decline. The key insight from Zook and Allen’s research is that managing these choke points requires a "founder’s mentality”—behaviors typically embodied by a bold, ambitious founder—to restore speed, focus, and connection to customers: • An insurgent’s clear mission and purpose • An unambiguous owner mindset • A relentless obsession with the front line Based on the authors’ decade-long study of companies in more than forty countries, The Founder’s Mentality demonstrates the strong relationship between these three traits in companies of all kinds—not just start-ups—and their ability to sustain performance. Through rich analysis and inspiring examples, this book shows how any leader—not only a founder—can instill and leverage a founder’s mentality throughout their organization and find lasting, profitable growth.

Friction by Roger Dooley

KShs3,499.00 KShs3,325.00
Brief Summary Annually, $4.6 trillion of merchandise is left in abandoned e-commerce shopping carts. Every year, the U.S. economy loses $3 trillion dollars in productivity due to excess bureaucracy. Red tape and over-complicated licenses have contributed to China's GDP exceeding India's by $82 trillion over the span of just three decades. If you're a business leader, these statistics should give you nightmares. According to science-based marketing and business expert Roger Dooley, they illustrate the real and growing threat of "friction," which he defines as the unnecessary expenditure of time, effort, or money in performing a task. In today's high-speed, customer-empowered world, the levels of swiftness and efficiency of business transactions will determine ultimate success or failure. In this groundbreaking guide, Dooley helps you spot the inevitable points of friction in your organization, and he provides the tools and insight you need to eliminate them. By truly understanding the impact friction can have, you'll be able to establish positive habits and eliminate negative ones--all with the end result of building a company that's the envy of your industry. Friction takes you step-by-step through the process of: Empowering frank conversations Guiding individual and team behaviors Getting ahead of friction Optimizing the customer experience Building a frictionless corporate culture Combining scientific research with real-life examples of leaders who have conquered business friction, Dooley teaches you how to identify roadblocks, alter them for the benefit of both business and customer, and create positive, lasting change. If you're in a leadership position, now is the time to declare war on friction--before your competitors do. Stamp out ridiculous rules, pointless procedures, and meaningless meetings. Become a relentless advocate for the customer and for minimizing customer effort. Lubricate every point of friction and make your company run like a well-oiled machine. Friction provides the know-how you need to lead your company to industry dominance ISBN:9781260135695 Author:Roger Dooley

Capital and Ideology by Thomas Piketty

KShs10,000.00 KShs9,290.00
The epic successor to one of the most important books of the century: at once a retelling of global history, a scathing critique of contemporary politics, and a bold proposal for a new and fairer economic system. Thomas Piketty's bestselling Capital in the Twenty-First Century galvanized global debate about inequality. In this audacious follow-up, Piketty challenges us to revolutionize how we think about politics, ideology, and history. He exposes the ideas that have sustained inequality for the past millennium, reveals why the shallow politics of right and left are failing us today, and outlines the structure of a fairer economic system. Our economy, Piketty observes, is not a natural fact. Markets, profits, and capital are all historical constructs that depend on choices. Piketty explores the material and ideological interactions of conflicting social groups that have given us slavery, serfdom, colonialism, communism, and hypercapitalism, shaping the lives of billions. He concludes that the great driver of human progress over the centuries has been the struggle for equality and education and not, as often argued, the assertion of property rights or the pursuit of stability. The new era of extreme inequality that has derailed that progress since the 1980s, he shows, is partly a reaction against communism, but it is also the fruit of ignorance, intellectual specialization, and our drift toward the dead-end politics of identity. Once we understand this, we can begin to envision a more balanced approach to economics and politics. Piketty argues for a new "participatory" socialism, a system founded on an ideology of equality, social property, education, and the sharing of knowledge and power. Capital and Ideology is destined to be one of the indispensable books of our time, a work that will not only help us understand the world, but that will change it.

Brief Summary You aspire to lead with greater impact. The problem is you’re busy executing on today’s demands. You know you have to carve out time from your day job to build your leadership skills, but it’s easy to let immediate problems and old mind-sets get in the way. Herminia Ibarra—an expert on professional leadership and development and a renowned professor at INSEAD, a leading international business school—shows how managers and executives at all levels can step up to leadership by making small but crucial changes in their jobs, their networks, and themselves. In Act Like a Leader, Think Like a Leader, she offers advice to help you: Redefine your job in order to make more strategic contributions Diversify your network so that you connect to, and learn from, a bigger range of stakeholders Become more playful with your self-concept, allowing your familiar—and possibly outdated—leadership style to evolve Ibarra turns the usual "think first and then act” philosophy on its head by arguing that doing these three things will help you learn through action and will increase what she calls your outsight—the valuable external perspective you gain from direct experiences and experimentation. As opposed to insight, outsight will then help change the way you think as a leader: about what kind of work is important; how you should invest your time; why and which relationships matter in informing and supporting your leadership; and, ultimately, who you want to become. Packed with self-assessments and practical advice to help define your most pressing leadership challenges, this book will help you devise a plan of action to become a better leader and move your career to the next level. It’s time to learn by doing. ISBN:9781422184127 Author:Herminia Ibarra

Six Simple Rules by Peter Tollman and...

KShs3,799.00 KShs3,610.00
Brief Summary Six Simple Rules: How to Manage Complexity without Getting Complicated. New tools for managing complexity Does your organization manage complexity by making things more complicated? If so, you are not alone. According to The Boston Consulting Group’s fascinating Complexity Index, business complexity has increased sixfold during the past sixty years. And, all the while, organizational complicatedness—that is, the number of structures, processes, committees, decision-making forums, and systems—has increased by a whopping factor of thirty-five. In their attempt to respond to the increasingly complex performance requirements they face, company leaders have created an organizational labyrinth that makes it more and more difficult to improve productivity and to pursue innovation. It also disengages and demotivates the workforce. Clearly it’s time for leaders to stop trying to manage complexity with their traditional tools and instead better leverage employees' intelligence. This book shows you how and explains the implications for designing and leading organizations. The way to manage complexity, the authors argue, is neither with the hard solutions of another era nor with the soft solutions—such as team building and feel-good "people initiatives”—that often follow in their wake. Based on social sciences (notably economics, game theory, and organizational sociology) and The Boston Consulting Group’s work with more than five hundred companies in more than forty countries and in various industries, authors Yves Morieux and Peter Tollman recommend six simple rules to manage complexity without getting complicated. Showing why the rules work and how to put them into practice, Morieux and Tollman give managers a much-needed tool to reinvigorate people in the face of seemingly endless complexity. Included are detailed examples from companies that have achieved a multiplicative effect on performance by using them. It’s time to manage complexity better. Employ these six simple rules to foster autonomy and cooperation and to effectively handle business complexity. As a result, you will improve productivity, innovate more, reengage your workforce, and seize opportunities to create competitive advantage. ISBN:9781422190555 Author:Peter Tollman and Yves Morieux
