Adapt: Why Success Always Starts with Failure


Tim Harford - 2011
    People can use economics and they can use statistics and numbers to get at the truth and there is a real appetite for doing so. This is such a BBC thing to say--there’s almost a public service mission to be fulfilled in educating people about economics. When I wrote The Undercover Economist, it was all about my pure enthusiasm for the subject; the book is full of stuff I wanted to say and that is always the thing with the books: they are always such fun to write. Do you think that people these days are generally more economically literate? People are now aware of economics for various reasons. There are the problems with the economy--there is always more interest in economics when it is all going wrong. Where is the border line in your new book between economics and sociology? I don’t draw a border line, and particularly not with the new book. The Undercover Economist was basically all the cool economics I could think of and The Logic of Life was me investigating a particular part of economics. All of the references in The Logic of Life were academic economics papers that I had related--and hopefully made more fun. This new book, Adapt, is very different. I have started by asking what is wrong with the world, what needs fixing, how does it work--and if economics can tell us something about that (which it can) then I have used it. And if economics is not the tool that you need--if you need to turn to sociology or engineering or biology or psychology--I have, in fact, turned to all of them in this book. If that’s what you need, then that’s where I have gone. So I have written this book in a different way: I started with a problem and tried to figure out how to solve it. What specific subjects do you tackle? To be a bit more specific, the book is about how difficult problems get solved and I look at quick change; the banking crisis; poverty; innovation, as I think there is an innovation slow-down; and the war in Iraq. Also, I look at both problems in business and in everyday life. Those are the big problems that I look at--and my conclusion is that these sorts of problems only ever get solved by trial and error, so when they are being solved, they are being solved through experimentation, which is often a bottom-up process. When they are not being solved it is because we are not willing to experiment, or to use trial and error. Do you think companies will change to be much more experimental, with more decisions placed in the hands of employees? I don’t think that is necessarily a trend, and the reason is that the market itself is highly experimental, so if your company isn’t experimental it may just happen to have a really great, successful idea--and that’s fine; if it doesn’t, it will go bankrupt. But that said, it is very interesting to look at the range of companies who have got very into experimentation--they range from the key-cutting chain Timpson’s to Google; you can’t get more different than those two firms, but actually the language is very similar; the recruitment policies are similar; the way the employees get paid is similar. The “strap line” of the book is that “Success always starts with failure.” You are a successful author… so what was the failure that set you up for success? I was working on a book before The Undercover Economist… it was going to be a sort of Adrian Mole/Bridget Jones’ Diary-styled fictional comedy, in which the hero was this economist and through the hilarious things that happened to him, all these economic principles would be explained--which is a great idea--but the trouble is that I am not actually funny. Another example would be my first job as a management consultant… and I was a terrible management consultant. I crashed out after a few months. Much better that, than to stick with the job for two or three years-- a lot of people say you have got to do that to “show your commitment.” Taking the job was a mistake--why would I need to show my commitment to a mistake? Better to realise you made a mistake, stop and do something else, which I did. That idea that “failure breeds success” is central to most entrepreneurs. Do you think we need more of it in the UK? I think that the real problem is not failure rates in business; the problem is failure rates in politics. We need a much higher failure rate in politics. What actually happens is politicians--and this is true of all political parties--have got some project and they’ll say, “Right, we are going to do this thing,” and it is quite likely that idea is a bad idea--because most ideas fail; the world is complicated and while I don’t have the numbers for this, most ideas are, as it turns out, not good ideas. But they never collect the data, or whatever it is they need to measure, to find out where their idea is failing. So they have this bad idea, roll this bad idea out and the bad idea sticks, costs the country hundreds, millions, or billions of pounds, and then the bad idea is finally reversed by the next party on purely ideological grounds and you never find out whether it really worked or not. So we have this very, very low willingness to collect the data that would be necessary to demonstrate failure, which is the bit we actually need. To give a brief example: Ken Livingstone, as Mayor of London, came along and introduced these long, bendy buses. Boris Johnson came along and said, “If you elect me, I am going to get rid of those big bendy buses and replace them with double-decker buses.” He was elected and he did it, so… which one of them is right? I don’t know. I mean, isn’t that crazy? I know democracy is a wonderful thing and we voted for Ken Livingstone and we voted for Boris Johnson, but it would be nice to actually have the data on passenger injury rates, how quickly people can get on and off these buses, whether disabled people are using these buses… the sort of basic evidence you would want to collect. Based on that, are you a supporter of David Cameron’s “Big Society”, which in a sense favours local experimentation over central government planning? Well, I have some sympathy for the idea of local experimentation, but what worries me is that we have to have some mechanism that is going to tell you what is working and what is not--and there is no proposal for that. Cameron’s Tories seem to have the view that ‘if it is local then it will work.’ In my book, I have all kinds of interesting case studies of situations where localism really would have worked incredibly well, as in, say, the US Army in Iraq. But I have also got examples of where localism did not work well at all--such as a corruption-fighting drive in Indonesia. Is the new book, Adapt, your movement away from economic rationalist to management guru? Are you going to cast your eye over bigger problems? The two changes in Adapt are that I have tried to start with the problem, rather than saying, “I have got a hammer--I’m going to look for a nail.” I started with a nail and said, “Ok, look, I need to get this hammered in.” So I have started with the problem and then looked anywhere for solutions. And the second thing is that I have tried to do is write with more of a narrative. This is not a Malcolm Gladwell book, but I really admire the way that people like Gladwell get quite complex ideas across because they get you interested in the story; that is something that I have tried to do more of here. I am not too worried about it, because I know that I am never going to turn into Malcolm Gladwell--I am always going to be Tim Harford--but it doesn’t hurt to nudge in a certain direction. On Amazon, we recommend new book ideas to people: “If you like Tim Harford you may like…”, but what does Tim Harford also like? I read a lot of books, mostly non-fiction and in two categories: people who I think write a lot better than I do, and people who think about economics more deeply than I do. In the first category I am reading people like Michael Lewis, Kathryn Schulz (I loved her first book, Being Wrong), Malcolm Gladwell and Alain de Botton. In the second category, I read lots of technical economics books, but I enjoy Steven Landsburg, Edward Glaeser (who has a book out now which looks good), Bill Easterly… I don’t necessarily agree with all of these people! When I am not reading non-fiction, I am reading comic books or 1980s fantasy authors like Jack Vance.

Tribes: We Need You to Lead Us


Seth Godin - 2008
    For millions of years, humans have been seeking out tribes, be they religious, ethnic, economic, political, or even musical (think of the Deadheads). It's our nature.Now the Internet has eliminated the barriers of geography, cost, and time. All those blogs and social networking sites are helping existing tribes get bigger. But more important, they're enabling countless new tribes to be born—groups of ten or ten thousand or ten million who care about their iPhones, or a political campaign, or a new way to fight global warming. And so the key question: Who is going to lead us?The Web can do amazing things, but it can't provide leadership. That still has to come from individuals—people just like you who have passion about something. The explosion in tribes means that anyone who wants to make a difference now has the tools at her fingertips.If you think leadership is for other people, think again—leaders come in surprising packages. Consider Joel Spolsky and his international tribe of scary-smart software engineers. Or Gary Vaynerhuck, a wine expert with a devoted following of enthusiasts. Chris Sharma leads a tribe of rock climbers up impossible cliff faces, while Mich Mathews, a VP at Microsoft, runs her internal tribe of marketers from her cube in Seattle. All they have in common is the desire to change things, the ability to connect a tribe, and the willingness to lead.If you ignore this opportunity, you risk turning into a "sheepwalker"—someone who fights to protect the status quo at all costs, never asking if obedience is doing you (or your organization) any good. Sheepwalkers don't do very well these days.Tribes will make you think (really think) about the opportunities in leading your fellow employees, customers, investors, believers, hobbyists, or readers. . . . It's not easy, but it's easier than you think.

Alchemy: The Surprising Power of Ideas That Don't Make Sense


Rory Sutherland - 2019
    Wonderfully applicable to everything in life, and funny as hell.’ Nassim Nicholas TalebTo be brilliant, you have to be irrationalWhy is Red Bull so popular – even though everyone hates the taste? Why do countdown boards on platforms take away the pain of train delays? And why do we prefer stripy toothpaste?We think we are rational creatures. Economics and business rely on the assumption that we make logical decisions based on evidence.But we aren’t, and we don’t.In many crucial areas of our lives, reason plays a vanishingly small part. Instead we are driven by unconscious desires, which is why placebos are so powerful. We are drawn to the beautiful, the extravagant and the absurd – from lavish wedding invitations to tiny bottles of the latest fragrance. So if you want to influence people’s choices you have to bypass reason. The best ideas don’t make rational sense: they make you feel more than they make you think.Rory Sutherland is the Ogilvy advertising legend whose TED Talks have been viewed nearly 7 million times. In his first book he blends cutting-edge behavioural science, jaw-dropping stories and a touch of branding magic, on his mission to turn us all into idea alchemists. The big problems we face every day, whether as an individual or in society, could very well be solved by letting go of logic and embracing the irrational.

Scaling Up: How a Few Companies Make It...and Why the Rest Don't (Rockefeller Habits 2.0)


Verne Harnish - 2014
    Scaling Up: How a Few Companies Make It...and Why the Rest Don't is the first major revision of this business classic. In Scaling Up, Harnish and his team share practical tools and techniques for building an industry-dominating business. These approaches have been honed from over three decades of advising tens of thousands of CEOs and executives and helping them navigate the increasing complexities (and weight) that come with scaling up a venture. This book is written so everyone -- from frontline employees to senior executives -- can get aligned in contributing to the growth of a firm. There's no reason to do it alone, yet many top leaders feel like they are the ones dragging the rest of the organization up the S-curve of growth. The goal of this book is to help you turn what feels like an anchor into wind at your back -- creating a company where the team is engaged; the customers are doing your marketing; and everyone is making money. To accomplish this, Scaling Up focuses on the four major decision areas every company must get right: People, Strategy, Execution, and Cash. The book includes a series of new one-page tools including the updated One-Page Strategic Plan and the Rockefeller Habits ChecklistTM, which more than 40,000 firms around the globe have used to scale their companies successfully -- many to $1 billion and beyond. Running a business is ultimately about freedom. Scaling Up shows business leaders how to get their organizations moving in sync to create something significant and enjoy the ride.

The Starfish and the Spider: The Unstoppable Power of Leaderless Organizations


Ori Brafman - 2006
    But if you cut off a starfish’s leg it grows a new one, and the old leg can grow into an entirely new starfish.What’s the hidden power behind the success of Wikipedia, Craigslist, and Skype? What do eBay and General Electric have in common with the abolitionist and women’s rights movements? What fundamental choice put General Motors and Toyota on vastly different paths? How could winning a Supreme Court case be the biggest mistake MGM could have made?After five years of ground-breaking research, Ori Brafman and Rod Beckstrom share some unexpected answers, gripping stories, and a tapestry of unlikely connections. The Starfish and the Spider argues that organizations fall into two categories: traditional “spiders,” which have a rigid hierarchy and top-down leadership, and revolutionary “starfish,” which rely on the power of peer relationships.The Starfish and the Spider explores what happens when starfish take on spiders (such as the music industry vs. Napster, Kazaa, and the P2P services that followed). It reveals how established companies and institutions, from IBM to Intuit to the US government, are also learning how to incorporate starfish principles to achieve success. The book explores:* How the Apaches fended off the powerful Spanish army for 200 years* The power of a simple circle* The importance of catalysts who have an uncanny ability to bring people together * How the Internet has become a breeding ground for leaderless organizations* How Alcoholics Anonymous has reached untold millions with only a shared ideology and without a leaderThe Starfish and the Spider is the rare book that will change how you understand the world around you.

Who Says Elephants Can't Dance?: Inside IBM's Historic Turnaround


Louis V. Gerstner Jr. - 2002
    By 1993, the computer industry had changed so rapidly the company was on its way to losing $16 billion and IBM was on a watch list for extinction -- victimized by its own lumbering size, an insular corporate culture, and the PC era IBM had itself helped invent.Then Lou Gerstner was brought in to run IBM. Almost everyone watching the rapid demise of this American icon presumed Gerstner had joined IBM to preside over its continued dissolution into a confederation of autonomous business units. This strategy, well underway when he arrived, would have effectively eliminated the corporation that had invented many of the industry's most important technologies.Instead, Gerstner took hold of the company and demanded the managers work together to re-establish IBM's mission as a customer-focused provider of computing solutions. Moving ahead of his critics, Gerstner made the hold decision to keep the company together, slash prices on his core product to keep the company competitive, and almost defiantly announced, "The last thing IBM needs right now is a vision."Who Says Elephants Can't Dance? tells the story of IBM's competitive and cultural transformation. In his own words, Gerstner offers a blow-by-blow account of his arrival at the company and his campaign to rebuild the leadership team and give the workforce a renewed sense of purpose. In the process, Gerstner defined a strategy for the computing giant and remade the ossified culture bred by the company's own success.The first-hand story of an extraordinary turnaround, a unique case study in managing a crisis, and a thoughtful reflection on the computer industry and the principles of leadership, Who Says Elephants Can't Dance? sums up Lou Gerstner's historic business achievement. Taking readers deep into the world of IBM's CEO, Gerstner recounts the high-level meetings and explains the pressure-filled, no-turning-back decisions that had to be made. He also offers his hard-won conclusions about the essence of what makes a great company run.In the history of modern business, many companies have gone from being industry leaders to the verge of extinction. Through the heroic efforts of a new management team, some of those companies have even succeeded in resuscitating themselves and living on in the shadow of their former stature. But only one company has been at the pinnacle of an industry, fallen to near collapse, and then, beyond anyone's expectations, returned to set the agenda. That company is IBM.Lou Gerstener, Jr., served as chairman and chief executive officer of IBM from April 1993 to March 2002, when he retired as CEO. He remained chairman of the board through the end of 2002. Before joining IBM, Mr. Gerstner served for four years as chairman and CEO of RJR Nabisco, Inc. This was preceded by an eleven-year career at the American Express Company, where he was president of the parent company and chairman and CEO of its largest subsidiary. Prior to that, Mr. Gerstner was a director of the management consulting firm of McKinsey & Co., Inc. He received a bachelor's degree in engineering from Dartmouth College and an MBA from Harvard Business School.

Lean Thinking: Banish Waste and Create Wealth in Your Corporation


James P. Womack - 1996
    It is based on the Toyota (lean) model, which combines operational excellence with value-based strategies to produce steady growth through a wide range of economic conditions. In contrast with the crash-and-burn performance of companies trumpeted by business gurus in the 1990s, the firms profiled in Lean Thinking -- from tiny Lantech to midsized Wiremold to niche producer Porsche to gigantic Pratt & Whitney -- have kept on keeping on, largely unnoticed, along a steady upward path through the market turbulence and crushed dreams of the early twenty-first century. Meanwhile, the leader in lean thinking -- Toyota -- has set its sights on leadership of the global motor vehicle industry in this decade. Instead of constantly reinventing business models, lean thinkers go back to basics by asking what the customer really perceives as value. (It's often not at all what existing organizations and assets would suggest.) The next step is to line up value-creating activities for a specific product along a value stream while eliminating activities (usually the majority) that don't add value. Then the lean thinker creates a flow condition in which the design and the product advance smoothly and rapidly at the pull of the customer (rather than the push of the producer). Finally, as flow and pull are implemented, the lean thinker speeds up the cycle of improvement in pursuit of perfection. The first part of this book describes each of these concepts and makes them come alive with striking examples. Lean Thinking clearly demonstrates that these simple ideas can breathe new life into any company in any industry in any country. But most managers need guidance on how to make the lean leap in their firm. Part II provides a step-by-step action plan, based on in-depth studies of more than fifty lean companies in a wide range of industries across the world. Even those readers who believe they have embraced lean thinking will discover in Part III that another dramatic leap is possible by creating an extended lean enterprise for each of their product families that tightly links value-creating activities from raw materials to customer. In Part IV, an epilogue to the original edition, the story of lean thinking is brought up-to-date with an enhanced action plan based on the experiences of a range of lean firms since the original publication of Lean Thinking. Lean Thinking does not provide a new management "program" for the one-minute manager. Instead, it offers a new method of thinking, of being, and, above all, of doing for the serious long-term manager -- a method that is changing the world.

Nine Lies About Work: A Freethinking Leader’s Guide to the Real World


Marcus Buckingham - 2019
    Strategic planning is essential. People's competencies should be measured and their weaknesses shored up. People crave feedback.These may sound like basic truths of our work lives today. But actually, they're lies. As strengths guru and bestselling author Marcus Buckingham and Cisco Leadership and Team Intelligence head Ashley Goodall show in this provocative, inspiring book, there are some big lies--distortions, faulty assumptions, wrong thinking--running through our organizational lives. Nine lies, to be exact. They cause dysfunction and frustration and ultimately result in a strange feeling of unreality that pervades our workplaces.But there are those who can get past the lies and discover what's real. These are freethinking leaders who recognize the power and beauty of our individual uniqueness, who know that emergent patterns are more valuable than received wisdom, and that evidence is more powerful than dogma. With engaging stories and incisive analysis, the authors reveal the essential truths that such freethinking leaders will recognize immediately: that it is the strength and cohesiveness of your team, not your company's culture, that matters most; that we need less focus on top-down planning and more on giving our people reliable, real-time intelligence; that rather than trying to align people's goals we should strive to align people's sense of purpose and meaning; that people don't want constant feedback, they want helpful attention. This is the real world of work.If you embrace each person's uniqueness and see this as key for all healthy organizations; if you reject dogma and engage with the real world; if you seek out emergent patterns and put your faith in evidence, not philosophy; if you thrill to the power of teams--if you do all of these, then you are a freethinking leader, and this book is for you.

The Back of the Napkin: Solving Problems and Selling Ideas with Pictures


Dan Roam - 2008
    Three dots to represent Dallas, Houston, and San Antonio. Three arrows to show direct flights. Problem solved, and the picture made it easy to sell Southwest Airlines to investors and customers. Used properly, a simple drawing on a humble napkin is more powerful than Excel or PowerPoint. It can help crystallize ideas, think outside the box, and communicate in a way that people simply “get”. In this book Dan Roam argues that everyone is born with a talent for visual thinking, even those who swear they can’t draw. Drawing on twenty years of visual problem solving combined with the recent discoveries of vision science, this book shows anyone how to clarify a problem or sell an idea by visually breaking it down using a simple set of visual thinking tools – tools that take advantage of everyone’s innate ability to look, see, imagine, and show. THE BACK OF THE NAPKIN proves that thinking with pictures can help anyone discover and develop new ideas, solve problems in unexpected ways, and dramatically improve their ability to share their insights. This book will help readers literally see the world in a new way.

Getting to Yes: Negotiating Agreement Without Giving In


Roger Fisher - 1981
    One of the primary business texts of the modern era, it is based on the work of the Harvard Negotiation Project, a group that deals with all levels of negotiation and conflict resolution. Getting to Yes offers a proven, step-by-step strategy for coming to mutually acceptable agreements in every sort of conflict. Thoroughly updated and revised, it offers readers a straight- forward, universally applicable method for negotiating personal and professional disputes without getting angry-or getting taken.This is by far the best thing I`ve ever read about negotiation. It is equally relevant for the individual who would like to keep his friends, property, and income and the statesman who would like to keep the peace." --John Kenneth Galbraith"

The Myths of Innovation


Scott Berkun - 2007
    We depend more than we realize on wishful thinking and romanticized ideas of history. In the new paperback edition of this fascinating book, a book that has appeared on MSNBC, CNBC, Slashdot.org, Lifehacker.com and in The New York Times, bestselling author Scott Berkun pulls the best lessons from the history of innovation, including the recent software and web age, to reveal powerful and suprising truths about how ideas become successful innovations -- truths people can easily apply to the challenges of today. Through his entertaining and insightful explanations of the inherent patterns in how Einstein’s discovered E=mc2 or Tim Berner Lee’s developed the idea of the world wide web, you will see how to develop existing knowledge into new innovations.Each entertaining chapter centers on breaking apart a powerful myth, popular in the business world despite it's lack of substance. Through Berkun's extensive research into the truth about innovations in technology, business and science, you’ll learn lessons from the expensive failures and dramatic successes of innovations past, and understand how innovators achieved what they did -- and what you need to do to be an innovator yourself. You'll discover:Why problems are more important than solutionsHow the good innovation is the enemy of the greatWhy children are more creative than your co-workersWhy epiphanies and breakthroughs always take timeHow all stories of innovations are distorted by the history effectHow to overcome people’s resistance to new ideasWhy the best idea doesn’t often winThe paperback edition includes four new chapters, focused on appling the lessons from the original book, and helping you develop your skills in creative thinking, pitching ideas, and staying motivated."For centuries before Google, MIT, and IDEO, modern hotbeds of innovation, we struggled to explain any kind of creation, from the universe itself to the multitudes of ideas around us. While we can make atomic bombs, and dry-clean silk ties, we still don’t have satisfying answers for simple questions like: Where do songs come from? Are there an infinite variety of possible kinds of cheese? How did Shakespeare and Stephen King invent so much, while we’re satisfied watching sitcom reruns? Our popular answers have been unconvincing, enabling misleading, fantasy-laden myths to grow strong." -- Scott Berkun, from the text"Berkun sets us free to change the world." -- Guy Kawasaki, author of Art of the StartScott was a manager at Microsoft from 1994-2003, on projects including v1-5 (not 6) of Internet Explorer.
