Developers of any kind of application should read this book." Grady Booch"A comprehensive solution to the requirements challenges faced by every development team. Full of insight and ideas all developers can learn from." Ivar JacobsonDespite the wealth of development knowledge, experience, and tools available today, a substantial percentage of software projects fail, often because requirements are not correctly determined and defined at the outset, or are not managed correctly as the project unfolds. This second edition of the popular text Managing Software Requirements focuses on this critical cause of failure and offers a practical, proven approach to building systems that meet customers' needs on time and within budget.Using an accessible style, their own war stories, and a comprehensive case study, the authors show how analysts and developers can effectively identify requirements by applying a variety of techniques, centered on the power of use cases. The book illustrates proven techniques for determining, implementing, and validating requirements. It describes six vital Team Skills for managing requirements throughout the lifecycle of a project: Analyzing the Problem, Understanding User Needs, Defining the System, Managing Scope, Refining the System Definition, and Building the Right System. Managing Software Requirements, Second Edition, specifically addresses the ongoing challenge of managing change and describes a process for assuring that project scope is successfully defined and agreed upon by all stakeholders.Topics covered include:The five steps in problem analysisBusiness modeling and system engineeringTechniques for eliciting requirements from customers and stakeholdersEstablishing and managing project scopeApplying and refining use casesProduct managementTransitioning from requirements to design and implementationTransitioning from use cases to test casesAgile requirements methods

    This book attempts to capture the engineering wisdom and design philosophy of the UNIX, Linux, and Open Source software development community as it has evolved over the past three decades, and as it is applied today by the most experienced programmers. Eric Raymond offers the next generation of hackers the unique opportunity to learn the connection between UNIX philosophy and practice through careful case studies of the very best UNIX/Linux programs.

    Monsarrat follows the great captains and naval adventurers from the Artic to the South Pacific. Lawe represents the spirit of maritime exploration and fortitude; his life is the thread stringing together a long history of nautical adventure.He finds himself mixed up with Drake and the Armada; sailing with Hudson in search of the North-West passage; a buccaneer under Sir Henry Morgan in the Caribbean; assisting Samuel Pepys with his responsibilities as Secretary to the Navy; at the side of Captain Cook as he transports General Wolf to the storming of Quebec, and then on to his death in the Pacific; serving in Nelson’s household and then to the Nile, Naples and Trafalgar; working on a slaver from Liverpool to the Caribbean; press-ganged aboard the Shannon just before her duel with the American Chesapeake, exploring the Artic with Sir John Franklin; fighting in both world wars, including the action at Zebrugge and ‘D’ Day; before a final test with a tanker catching fire after the opening of the St.Lawrence Seaway – and much more besides!Under sail and steam, as Mathew’s eternal existence progresses, the action-packed novel is both highly entertaining and instructive and has been widely acclaimed as a masterpiece. Some fourteen true maps, along with other diagrams, are included, and what was originally two volumes is supplied as one. ‘… this huge, action packed volume can be recommended to anyone’ – Sunday Times‘He has never written anything to compare with this work – it is a masterstroke’ – Manchester Evening News‘No one can bring alive the cruel sea and the valiant men who have sailed on it through all the generations like Monsarrat’ – Daily Mail‘This is Monsarrat, master storyteller, running proud’ – The ScotsmanNote: Nicholas Monsarrat died before Book II was finished. Anne Monsarrat completed the remainder of the story in Nicholas's own words, partly from some working notes he left and partly from his original synopsis of The Master Mariner Book II. Both are included here.

    And I mean all the time. Every day there’s a new cloud-based dating app; a new cloud-based gizmo for your house; a new cloud-based game; or a thousand other new things—all in the cloud.The cloud is everywhere! Everything is in the cloud! What does it mean! Let’s slow down. Take a deep breath. That’s good. Take another. Excellent. This book teaches you all about the cloud. I’ll let you in on a little secret: the cloud is not that hard to understand. It’s not. It’s just that nobody has taken the time to explain to you what the cloud is. They haven’t, have they?Deep down I think this is because they don’t understand the cloud either, but I do. I’ve been a programmer and writer for over 30 years. I’ve been in cloud computing since the very start, and I’m here to help you on your journey to understand the cloud. Consider me your tour guide. I’ll be with you every step of the way, but not in a creepy way.I take my time with this book. I go slow and easy, so you can build up an intuition about what the cloud really is, one idea at a time. When you finish reading, you’ll understand the cloud. When you hear someone say some new cool thing is in the cloud, you’ll understand exactly what they mean. That’s a promise. How do I deliver on that promise? I use lots and lots of pictures. I use lots and lots of examples. We’ll reveal the secret inner-workings of AWS, Netflix, Facebook Messenger, Amazon Kindle, Apple iCloud, Google Maps, Nest and cloud DVRs. You’ll learn by seeing and understanding; no matter if you're a complete beginner, someone who knows a little and wants to learn more, or a programmer looking to change their career to the cloud.The cloud is the future. You don't want to miss out on the future, do you? Read this book and we'll discover it together.I’m excited. This will be fun. Let’s get started!

    Plenty of books describe what agile development is or why it helps software projects succeed, but very few combine information for developers, managers, testers, and customers into a single package that they can apply directly. This book provides no-nonsense advice on agile planning, development, delivery, and management taken from the authors' many years of experience with Extreme Programming (XP). You get a gestalt view of the agile development process, including comprehensive guidance for non-technical readers and hands-on technical practices for developers and testers. The Art of Agile Development gives you clear answers to questions such as:How can we adopt agile development? Do we really need to pair program? What metrics should we report? What if I can't get my customer to participate? How much documentation should we write? When do we design and architect? As a non-developer, how should I work with my agile team? Where is my product roadmap? How does QA fit in? The book teaches you how to adopt XP practices, describes each practice in detail, then discusses principles that will allow you to modify XP and create your own agile method. In particular, this book tackles the difficult aspects of agile development: the need for cooperation and trust among team members. Whether you're currently part of an agile team, working with an agile team, or interested in agile development, this book provides the practical tips you need to start practicing agile development. As your experience grows, the book will grow with you, providing exercises and information that will teach you first to understand the rules of agile development, break them, and ultimately abandon rules altogether as you master the art of agile development. "Jim Shore and Shane Warden expertly explain the practices and benefits of Extreme Programming. They offer advice from their real-world experiences in leading teams. They answer questions about the practices and show contraindications - ways that a practice may be mis-applied. They offer alternatives you can try if there are impediments to applying a practice, such as the lack of an on-site customer. --Ken Pugh, Author of Jolt Award Winner, Prefactoring "I will leave a copy of this book with every team I visit." --Brian Marick, Exampler Consulting
