The Lean Startup movement is very promising, but for many teams it ends up translating into an important question: ”Yeah, but what to build ?” “In ThoughtWorks, our response has been a process called an inception. We gather together a good sample of the people who will be affected by the product and have an intensive session to set an initial direction, using a series of exercises focusing on collaboration and the capture of broad goals. We don't attempt a detailed specification, as that is exactly the kind of thing that becomes out of date as soon as code hits production. But we do want to understand what kind of outcomes we are hoping for, the features that we think will drive these outcomes, and how to assess the effectiveness of our product. With The Lean Inception, Paulo has captured his experience in running these inceptions over the last decade. In particular it's focused on his work to boil the inception down to its essence, concentrating the activity on a single, if very intensive, week of work. Paulo shares how he makes this work, through writing a product vision, capturing personas, understanding the user journeys, and developing high-level features. The result isn't a detailed plan of work, which we find quickly rots into irrelevance. It is a guiding set of goals to set us off in the right direction. It doesn't plan out a final product, with all the features that our users will need, instead it focuses on an initial product that we can release and learn from - the Minimum Viable Product. “ – Martin Fowler, Chief Cientist at ThoughtWorks

    Our increasingly complex world demands that we continuously learn from failures (and successes) in order to survive and thrive. And yet, our learning is too often undermined. We construct biased but comfortable stories, which often feature a simple, single "root cause"--a villain, someone to take the blame. Having done that, we short-circuit the possibility of developing any deeper understanding of the complex systems we work with. With this common approach, our systems will become more fragile and drift into failure. In this concise and entertaining book, I.T. veteran Dave Zwieback describes an incident that threatens the very existence of a large financial institution, and the counterintuitive steps its leadership took to stop the downward spiral. Their novel approach is grounded in proven concepts from complexity science, resilience engineering, human factors, cognitive science, and organizational psychology. It allows us to identify the underlying conditions for failure, and make our systems (and organizations) safer and more resilient.- Get a clear understanding of the downside of blame- Learn how to identify (and counteract) cognitive biases in groups- See how organizations can determine the real root cause of problems- Establish real accountability with your organization- Use the Learning Review Framework to fully learn from failures of complex systems- Find practical insights and tips for moving beyond blame in your own organization

    More than any other language, Python was created with the philosophy of simplicity and parsimony. Now 25 years old, Python has become the primary or secondary language (after SQL) for many business users. With popularity comes diversity--and possibly dilution.This guide, collaboratively written by over a hundred members of the Python community, describes best practices currently used by package and application developers. Unlike other books for this audience, The Hitchhiker's Guide is light on reusable code and heavier on design philosophy, directing the reader to excellent sources that already exist.

    Almost 30 years later, at the pinnacle of his success as founder and leader of Dell Technologies, he found himself embroiled in a battle for his company's survival. What he'd do next could ensure its legacy--or destroy it completely.Play Nice But Win is a riveting account of the three battles waged for Dell Technologies: one to launch it, one to keep it, and one to transform it. For the first time, Dell reveals the highs and lows of the company's evolution amidst a rapidly changing industry--and his own, as he matured into the CEO it needed. With humor and humility, he recalls the mentors who showed him how to turn his passion into a business; the competitors who became friends, foes, or both; and the sharks that circled, looking for weakness. What emerges is the long-term vision underpinning his success: that technology is ultimately about people and their potential.More than an honest portrait of a leader at a crossroads, Play Nice But Win is a survival story proving that while anyone with technological insight and entrepreneurial zeal might build something great--it takes a leader to build something that lasts.

    Less than 20 years after its founding, it boasts the largest constellation of commercial satellites in orbit, has pioneered reusable rockets, and in 2020 became the first private company to launch human beings into orbit. Half a century after the space race it is private companies, led by SpaceX, standing alongside NASA pushing forward into the cosmos, and laying the foundation for our exploration of other worlds.But before it became one of the most powerful players in the aerospace industry, SpaceX was a fledgling startup, scrambling to develop a single workable rocket before the money ran dry. The engineering challenge was immense; numerous other private companies had failed similar attempts. And even if SpaceX succeeded, they would then have to compete for government contracts with titans such as Lockheed Martin and Boeing, who had tens of thousands of employees and tens of billions of dollars in annual revenue. SpaceX had fewer than 200 employees and the relative pittance of $100 million in the bank.In Liftoff, Eric Berger, senior space editor at Ars Technica, takes readers inside the wild early days that made SpaceX. Focusing on the company’s first four launches of the Falcon 1 rocket, he charts the bumpy journey from scrappy underdog to aerospace pioneer. We travel from company headquarters in El Segundo, to the isolated Texas ranchland where they performed engine tests, to Kwajalein, the tiny atoll in the Pacific where SpaceX launched the Falcon 1. Berger has reported on SpaceX for more than a decade, enjoying unparalleled journalistic access to the company’s inner workings. Liftoff is the culmination of these efforts, drawing upon exclusive interviews with dozens of former and current engineers, designers, mechanics, and executives, including Elon Musk. The enigmatic Musk, who founded the company with the dream of one day settling Mars, is the fuel that propels the book, with his daring vision for the future of space.Filled with never-before-told stories of SpaceX’s turbulent beginning, Liftoff is a saga of cosmic proportions.

    He draws ideas from three very useful intellectual pools: classical management practices, Agile methods, and lean product development. By combining the strengths of these three approaches, he has produced something that works better than any one in isolation." -From the Foreword by Don Reinertsen, President of Reinertsen & Associates; author of Managing the Design Factory; and leading expert on rapid product development Effective requirements discovery and analysis is a critical best practice for serious application development. Until now, however, requirements and Agile methods have rarely coexisted peacefully. For many enterprises considering Agile approaches, the absence of effective and scalable Agile requirements processes has been a showstopper for Agile adoption. In Agile Software Requirements, Dean Leffingwell shows exactly how to create effective requirements in Agile environments. Part I presents the "big picture" of Agile requirements in the enterprise, and describes an overall process model for Agile requirements at the project team, program, and portfolio levels Part II describes a simple and lightweight, yet comprehensive model that Agile project teams can use to manage requirements Part III shows how to develop Agile requirements for complex systems that require the cooperation of multiple teams Part IV guides enterprises in developing Agile requirements for ever-larger "systems of systems," application suites, and product portfolios This book will help you leverage the benefits of Agile without sacrificing the value of effective requirements discovery and analysis. You'll find proven solutions you can apply right now-whether you're a software developer or tester, executive, project/program manager, architect, or team leader.
