Single Point Of Failure

Over the past decade organizations have faced relentless customer demand for better value at less cost, individual customization, greater choice, faster delivery, higher quality, exceptional service, and more recently – increased environmental and social consciousness. The organization’s weapon of choice to address this increasing demand has been the supply chain. However, as the supply chain footprint changed (e.g. outsourcing, off-shoring and customer/vendor empowerment) so did the organization’s exposure to uncertainty. Organizations were taken by surprise since this exposure was unanticipated, complex and beyond their ability to manage. As customers become more demanding and change occurs at an even greater pace, supply chain risk continues to propagate like a parasite. Organizations and societies are at much greater risk of systemic failure because of the massive interdependency throughout global supply chains. The priority now is two-fold; play catch-up and address these massive gaps while deploying more intelligent and integrated strategies (i.e. social aware, instinctive, dynamic and predictive) for dealing with continuous change. Single Point of Failure: The 10 Essential Laws of Supply Chain Risk Management uses analogies and dozens of case histories to describe the risk parasite that infects all supply chains while revealing methods to neutralize that parasite. The book addresses the questions: What are the "single points of failure"? How exposed are customers, investors, other stakeholders and ultimately the organization? What is the measurable impact (i.e. brand, financial, strategic, and non-compliance)? Who establishes the "risk paradigm"? How does the organization efficiently and effectively allocate precious resources - time, people, management attention, and capital? How is success measured? This book is both technically powerful and effectively realistic, based on today's complex global economy.

Winner of the 2019 National Business Book Award A groundbreaking take on how complexity causes failure in all kinds of modern systems—from social media to air travel—this practical and entertaining book reveals how we can prevent meltdowns in business and life. A crash on the Washington, D.C. metro system. An accidental overdose in a state-of-the-art hospital. An overcooked holiday meal. At first glance, these disasters seem to have little in common. But surprising new research shows that all these events—and the myriad failures that dominate headlines every day—share similar causes. By understanding what lies behind these failures, we can design better systems, make our teams more productive, and transform how we make decisions at work and at home. Weaving together cutting-edge social science with riveting stories that take us from the frontlines of the Volkswagen scandal to backstage at the Oscars, and from deep beneath the Gulf of Mexico to the top of Mount Everest, Chris Clearfield and András Tilcsik explain how the increasing complexity of our systems creates conditions ripe for failure and why our brains and teams can't keep up. They highlight the paradox of progress: Though modern systems have given us new capabilities, they've become vulnerable to surprising meltdowns—and even to corruption and misconduct. But Meltdown isn't just about failure; it's about solutions—whether you're managing a team or the chaos of your family's morning routine. It reveals why ugly designs make us safer, how a five-minute exercise can prevent billion-dollar catastrophes, why teams with fewer experts are better at managing risk, and why diversity is one of our best safeguards against failure. The result is an eye-opening, empowering, and entirely original book—one that will change the way you see our complex world and your own place in it.

This is the comprehensive guide to Linux on the mainframe straight from the IBM Linux experts. The book covers virtualization, security, systems management, and more.

If you want your startup to succeed, you need to understand why startups fail. “Whether you’re a first-time founder or looking to bring innovation into a corporate environment, Why Startups Fail is essential reading.”—Eric Ries, founder and CEO, LTSE, and New York Times bestselling author of The Lean Startup and The Startup Way Why do startups fail? That question caught Harvard Business School professor Tom Eisenmann by surprise when he realized he couldn’t answer it. So he launched a multiyear research project to find out. In Why Startups Fail, Eisenmann reveals his findings: six distinct patterns that account for the vast majority of startup failures. • Bad Bedfellows. Startup success is thought to rest largely on the founder’s talents and instincts. But the wrong team, investors, or partners can sink a venture just as quickly. • False Starts. In following the oft-cited advice to “fail fast” and to “launch before you’re ready,” founders risk wasting time and capital on the wrong solutions. • False Promises. Success with early adopters can be misleading and give founders unwarranted confidence to expand. • Speed Traps. Despite the pressure to “get big fast,” hypergrowth can spell disaster for even the most promising ventures. • Help Wanted. Rapidly scaling startups need lots of capital and talent, but they can make mistakes that leave them suddenly in short supply of both. • Cascading Miracles. Silicon Valley exhorts entrepreneurs to dream big. But the bigger the vision, the more things that can go wrong. Drawing on fascinating stories of ventures that failed to fulfill their early promise—from a home-furnishings retailer to a concierge dog-walking service, from a dating app to the inventor of a sophisticated social robot, from a fashion brand to a startup deploying a vast network of charging stations for electric vehicles—Eisenmann offers frameworks for detecting when a venture is vulnerable to these patterns, along with a wealth of strategies and tactics for avoiding them. A must-read for founders at any stage of their entrepreneurial journey, Why Startups Fail is not merely a guide to preventing failure but also a roadmap charting the path to startup success.
