Book Description
Writing use cases as a means of capturing the behavioral requirements of software systems and business processes is a practice that is quickly gaining popularity. Use cases provide a beneficial means of project planning because they clearly show how people will ultimately use the system being designed. On the surface, use cases appear to be a straightforward and simple concept. Faced with the task of writing a set of use cases, however, practitioners must ask: "How exactly am I supposed to write use cases?" Because use cases are essentially prose essays, this question is not easily answered, and as a result, the task can become formidable. In Writing Effective Use Cases, object technology expert Alistair Cockburn presents an up-to-date, practical guide to use case writing. The author borrows from his extensive experience in this realm, and expands on the classic treatments of use cases to provide software developers with a "nuts-and-bolts" tutorial for writing use cases. The book thoroughly covers introductory, intermediate, and advanced concepts, and is, therefore, appropriate for all knowledge levels. Illustrative writing examples of both good and bad use cases reinforce the author's instructions. In addition, the book contains helpful learning exercises--with answers--to illuminate the most important points. Highlights of the book include: A thorough discussion of the key elements of use cases--actors, stakeholders, design scope, scenarios, and more A use case style guide with action steps and suggested formats An extensive list of time-saving use case writing tips A helpful presentation of use case templates, with commentary on when and where they should be employed A proven methodology for taking advantage of use cases With this book as your guide, you will learn the essential elements of use case writing, improve your use case writing skills, and be well on your way to employing use cases effectively for your next development project.

Book Description
Use cases have never been this easy to understand -- or this easy to create! In Writing Effective Use Cases, Alistair Cockburn offers a hands-on, soup-to-nuts guide to use case development, based on the proven concepts he has refined through years of research, development, and seminar presentations. Cockburn begins by answering the most basic questions facing anyone interested in use cases: "What does a use case look like? When do I write one?" Next, he introduces each key element of use cases: actors, stakeholders, design scope, goal levels, scenarios, and more. Writing Effective Use Cases contains detailed guidelines, formats, and project standards for creating use cases -- as well as a detailed chapter on style, containing specific do's and don'ts. Cockburn shows how use cases fit together with requirements gathering, business processing reengineering, and other key issues facing software professionals. The book includes practice exercises with solutions, as well as a detailed appendix on how to use these techniques with UML. For all application developers, object technology practitioners, software system designers, architects, and analysts.

Book Description
“If the purpose is to create one of the best books on requirements yet written, the authors have succeeded.” —Capers Jones Software can solve almost any problem. The trick is knowing what the problem is. With about half of all software errors originating in the requirements activity, it is clear that a better understanding of the problem is needed. Getting the requirements right is crucial if we are to build systems that best meet our needs. We know, beyond doubt, that the right requirements produce an end result that is as innovative and beneficial as it can be, and that system development is both effective and efficient. Mastering the Requirements Process: Getting Requirements Right, Third Edition, sets out an industry-proven process for gathering and verifying requirements, regardless of whether you work in a traditional or agile development environment. In this sweeping update of the bestselling guide, the authors show how to discover precisely what the customer wants and needs, in the most efficient manner possible.

Writing Effective User Stories

Writing Effective User Stories PDF Author: Thomas and Angela Hathaway
Publisher: BA-Experts
ISBN:
Category : Business & Economics
Languages : en
Pages : 54

Book Description
WHAT IS THIS BOOK ABOUT? This Book Is About the “Card” (User Story: Card, Criteria, Conversation) User Stories are a great method for expressing stakeholder requirements, whether your projects follow an Agile, Iterative, or a Waterfall methodology. They are the basis for developers to deliver a suitable information technology (IT) app or application. Well-structured user stories express a single action to achieve a specific goal from the perspective of a single role. When writing user stories, stakeholders knowledgeable about the role should focus on the business result that the IT solution will enable while leaving technology decisions up to the developers. Good user stories are relevant to the project, unambiguous, and understandable to knowledge peers. The best user stories also contain crucial non-functional (quality) requirements, which are the best weapon in the war against unsatisfactory performance in IT solutions. This book presents two common user story structures to help you ensure that your user stories have all the required components and that they express the true business need as succinctly as possible. It offers five simple rules to ensure that your user stories are the best that they can be. That, in turn, will reduce the amount of time needed in user story elaboration and discussion with the development team. This book targets business professionals who are involved with an IT project, Product Owners in charge of managing a backlog, or Business Analysts working with an Agile team. Author’s Note The term “User Story” is a relative new addition to our language and its definition is evolving. In today’s parlance, a complete User Story has three primary components, namely the “Card”, the “Conversation”, and the “Criteria”. Different roles are responsible for creating each component. The “Card” expresses a business need. A representative of the business community is responsible for expressing the business need. Historically (and for practical reasons) the “Card” is the User Story from the perspective of the business community. Since we wrote this book specifically to address that audience, we use the term “User Story” in that context throughout. The “Conversation” is an ongoing discussion between a developer responsible for creating software that meets the business need and the domain expert(s) who defined it (e.g., the original author of the “Card”). The developer initiates the “Conversation” with the domain expert(s) to define the “Criteria” and any additional information the developer needs to create the application. There is much to be written about both the “Conversation” and the “Criteria”, but neither component is dealt with in any detail in this publication. A well-written User Story (“Card”) can drastically reduce the time needed for the “Conversation”. It reduces misinterpretations, misunderstandings, and false starts, thereby paving the way for faster delivery of working software. We chose to limit the content of this publication to the “User Story” as understood by the business community to keep the book focused and address the widest possible audience. WHO WILL BENEFIT FROM READING THIS BOOK? How organizations develop and deliver working software has changed significantly in recent years. Because the change was greatest in the developer community, many books and courses justifiably target that group. There is, however, an overlooked group of people essential to the development of software-as-an-asset that have been neglected. Many distinct roles or job titles in the business community perform business needs analysis for digital solutions. They include: - Product Owners - Business Analysts - Requirements Engineers - Test Developers - Business- and Customer-side Team Members - Agile Team Members - Subject Matter Experts (SME) - Project Leaders and Managers - Systems Analysts and Designers - AND “anyone wearing the business analysis hat”, meaning anyone responsible for defining a future IT solution TOM AND ANGELA’S (the authors) STORY Like all good IT stories, theirs started on a project many years ago. Tom was the super techie, Angela the super SME. They fought their way through the 3-year development of a new policy maintenance system for an insurance company. They vehemently disagreed on many aspects, but in the process discovered a fundamental truth about IT projects. The business community (Angela) should decide on the business needs while the technical team’s (Tom)’s job was to make the technology deliver what the business needed. Talk about a revolutionary idea! All that was left was learning how to communicate with each other without bloodshed to make the project a resounding success. Mission accomplished. They decided this epiphany was so important that the world needed to know about it. As a result, they made it their mission (and their passion) to share this ground-breaking concept with the rest of the world. To achieve that lofty goal, they married and began the mission that still defines their life. After over 30 years of living and working together 24x7x365, they are still wildly enthusiastic about helping the victims of technology learn how to ask for and get the digital (IT) solutions they need to do their jobs better. More importantly, they are more enthusiastically in love with each other than ever before!

How to Write Effective Requirements for IT – Simply Put!

How to Write Effective Requirements for IT – Simply Put! PDF Author: Thomas and Angela Hathaway
Publisher: BA-Experts
ISBN:
Category : Business & Economics
Languages : en
Pages : 128

Book Description
WHAT IS THIS BOOK ABOUT? Effective Requirements Reduce Project Failures Writing requirements is one of the core competencies for anyone in an organization responsible for defining future Information Technology (IT) applications. However, nearly every independently executed root-cause analysis of IT project problems and failures in the past half-century have identified “misunderstood or incomplete requirements” as the primary cause. This has made writing requirements the bane of many projects. The real problem is the subtle differences between “understanding” someone else’s requirement and “sharing a common understanding” with the author. “How to Write Effective Requirements for IT – Simply Put!” gives you a set of 4 simple rules that will make your requirement statements more easily understood by all target audiences. The focus is to increase the “common understanding” between the author of a requirement and the solution providers (e.g., in-house or outsourced IT designers, developers, analysts, and vendors). The rules we present in this book will reduce the failure rate of projects suffering from poor requirements. Regardless of your job title or role, if you are tasked with communicating your future needs to others, this book is for you. How to Get the Most out of this Book? To maximize the learning effect, you will have optional, online exercises to assess your understanding of each presented technique. Chapter titles prefaced with the phrase “Exercise” contain a link to a web-based exercise that we have prepared to give you an opportunity to try the presented technique yourself. These exercises are optional and they do not “test” your knowledge in the conventional sense. Their purpose is to demonstrate the use of the technique more real-life than our explanations can supply. You need Internet access to perform the exercises. We hope you enjoy them and that they make it easier for you to apply the techniques in real life. Specifically, this eWorkbook will give you techniques to: - Express business and stakeholder requirements in simple, complete sentences - Write requirements that focus on the business need - Test the relevance of each requirement to ensure that it is in scope for your project - Translate business needs and wants into requirements as the primary tool for defining a future solution and setting the stage for testing - Create and maintain a question file to reduce the impact of incorrect assumptions - Minimize the risk of scope creep caused by missed requirements - Ensure that your requirements can be easily understood by all target audiences - Confirm that each audience shares a mutual understanding of the requirements - Isolate and address ambiguous words and phrases in requirements. - Use our Peer Perception technique to find words and phrases that can lead to misunderstandings. - Reduce the ambiguity of a statement by adding context and using standard terms and phrases TOM AND ANGELA’S (the authors) STORY Like all good IT stories, theirs started on a project many years ago.
