    However, large-scale agile development is difficult, and publicly available case studies have been scarce. Now, three agile pioneers at Hewlett-Packard present a candid, start-to-finish insider's look at how they've succeeded with agile in one of the company's most mission-critical software environments: firmware for HP LaserJet printers.This book tells the story of an extraordinary experiment and journey. Could agile principles be applied to re-architect an enormous legacy code base? Could agile enable both timely delivery and ongoing innovation? Could it really be applied to 400+ developers distributed across four states, three continents, and four business units? Could it go beyond delivering incremental gains, to meet the stretch goal of 10x developer productivity improvements?It could, and it did--but getting there was not easy.Writing for both managers and technologists, the authors candidly discuss both their successes and failures, presenting actionable lessons for other development organizations, as well as approaches that have proven themselves repeatedly in HP's challenging environment. They not only illuminate the potential benefits of agile in large-scale development, they also systematically show how these benefits can actually be achieved.Coverage includes: - Tightly linking agile methods and enterprise architecture with business objectives- Focusing agile practices on your worst development pain points to get the most bang for your buck- Abandoning classic agile methods that don't work at the largest scale- Employing agile methods to establish a new architecture- Using metrics as a "conversation starter" around agile process improvements- Leveraging continuous integration and quality systems to reduce costs, accelerate schedules, and automate the delivery pipeline- Taming the planning beast with "light-touch" agile planning and lightweight long-range forecasting- Implementing effective project management and ensuring accountability in large agile projects- Managing tradeoffs associated with key decisions about organizational structure- Overcoming U.S./India cultural differences that can complicate offshore development- Selecting tools to support quantum leaps in productivity in your organization- Using change management disciplines to support greater enterprise agility

    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.

    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.

    Creativity, Inc. is a book for managers who want to lead their employees to new heights, a manual for anyone who strives for originality, and the first-ever, all-access trip into the nerve center of Pixar Animation—into the meetings, postmortems, and “Braintrust” sessions where some of the most successful films in history are made. It is, at heart, a book about how to build a creative culture—but it is also, as Pixar co-founder and president Ed Catmull writes, “an expression of the ideas that I believe make the best in us possible.” For nearly twenty years, Pixar has dominated the world of animation, producing such beloved films as the Toy Story trilogy, Monsters, Inc., Finding Nemo, The Incredibles, Up, and WALL-E, which have gone on to set box-office records and garner thirty Academy Awards. The joyousness of the storytelling, the inventive plots, the emotional authenticity: In some ways, Pixar movies are an object lesson in what creativity really is. Here, in this book, Catmull reveals the ideals and techniques that have made Pixar so widely admired—and so profitable.   As a young man, Ed Catmull had a dream: to make the first computer-animated movie. He nurtured that dream as a Ph.D. student at the University of Utah, where many computer science pioneers got their start, and then forged a partnership with George Lucas that led, indirectly, to his founding Pixar with Steve Jobs and John Lasseter in 1986. Nine years later, Toy Story was released, changing animation forever. The essential ingredient in that movie’s success—and in the thirteen movies that followed—was the unique environment that Catmull and his colleagues built at Pixar, based on philosophies that protect the creative process and defy convention, such as:   • Give a good idea to a mediocre team, and they will screw it up. But give a mediocre idea to a great team, and they will either fix it or come up with something better. • If you don’t strive to uncover what is unseen and understand its nature, you will be ill prepared to lead. • It’s not the manager’s job to prevent risks. It’s the manager’s job to make it safe for others to take them. • The cost of preventing errors is often far greater than the cost of fixing them. • A company’s communication structure should not mirror its organizational structure. Everybody should be able to talk to anybody. • Do not assume that general agreement will lead to change—it takes substantial energy to move a group, even when all are on board.
