Book Description
WHAT IS THIS BOOK ABOUT? Learn about Data Flow Diagrams (DFDs), Context-level DFDs, and Rigorous Physical Process Models (RPPM), what they are, why they are important, and who can use them. Use Data Flow Diagrams to Visualize Workflows An old Chinese proverb says, “A picture is worth a thousand words.” In the world of Information Technology (IT), we maintain that it may even be worth a whole lot more. For most people, it is difficult or impossible to envision a process flow, especially when someone else is describing it. Understanding current workflows, however, is critical to defining a future IT solution. Just as critical is understanding how data is created and consumed throughout the workflow. To truly understand problems inherent in a business process or workflow, you need to help the practitioners visualize what they do. Visualization lets them identify better ways of working that remove current restrictions. Data Flow Diagrams are phenomenal tools for visualization. Working with business experts, you can help them identify problems and inefficiencies they don’t even know they have. These are not people problems; they are process problems. Understanding when and how to create and use Data Flow Diagrams will help you discover and capture the requirements for improving the use of information technology. Why Should You Take this Course? In “Data Flow Diagrams – Simply Put!”, you will learn the benefits of process visualization for the business community, for the one wearing the BA hat, for those tasked with developing the solution, and ultimately for the entire organization. You will also discover how DFDs are powerful tools for recognizing and eliminating two of the major problems that haunt IT projects, namely Scope Creep and Project Overruns caused by late project change requests. This book uses a concrete business scenario to present a simple, easy-to-learn approach for creating and using Data Flow Diagrams depicting workflow and data manipulation from interviews with Subject Matter Experts. You will learn how to create a Context-Level Data Flow Diagram and explode relevant process(es) to reveal the nitty-gritty detail (i.e., individual process and data specifications) that developers need to create IT solutions that the business community needs. This book answers the following questions: - What is a Data Flow Diagram (DFD)? - What is a Rigorous Physical Process Model? - What is a Context-Level DFD? - Why should I use Data Flow Diagrams? - What symbols can I use on each type of diagram? - How can I drill down into a process? - How can I show internal processes and flows that produce the results? - What does balancing a Data Flow Diagram mean and what is the business value? - What is the most efficient approach to balancing a DFD? - What business value do process specifications offer? - How can I express detailed specifications for processes and data? - What is “metadata" and why do you need it? - What does a fully balanced DFD look like? - What value does a DFD fragment provide? - Regardless of your job title or role, if you are tasked with communicating a workflow or functional requirements to others, this book is for you. WHO WILL BENEFIT FROM READING THIS BOOK? 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!

Book Description
WHAT IS THIS BOOK ABOUT? Do You Need Requirements Interviews and Workshops? A lot of initial uncertainty at the beginning of an IT project comes from not knowing how to approach stakeholders to get their requirements. Should you interview each stakeholder individually or in groups? Whom should you interview first? What can you do to guide stakeholders to give you the information you need to formulate the right requirements? Unfortunately getting other stakeholders to express their needs and wants vis-à-vis a proposed IT solution is a non-trivial challenge. On top of that, you might be dealing with cross-functional needs which complicates the task even more. To meet that challenge, we propose that you need to hone your interpersonal skills, in particular your interviewing skills. If you have never interviewed another person before, this task alone can be intimidating. Why Should You Read This Book? Since interviewing other people for requirements is not an intuitive skill, this book presents a wide range of techniques for planning, preparing, and performing requirements elicitation interviews and workshops as well as polishing and publishing the results. It defines the characteristics of a good requirements interviewer to help you recognize areas for personal growth. To guide you through the intricacies of conducting group interviews, it includes expert advice on facilitating effective Requirements Workshops (JAD, RDW, User Story Workshops, Requirements Gathering Workshops, etc.), a powerful requirements elicitation technique for managing cross-functional group meetings on traditional and Agile software development methodologies. Specifically, this book will help you get more and better requirements by teaching you how to: - Define and distinguish five specific requirements elicitation approaches for interviewing stakeholders - Evaluate the pros and cons of each approach for your organization and project - Recognize the specific challenges and strengths of facilitated requirements workshops involving cross-functional groups of stakeholders - Select the right requirements interviewing mode - Prepare, perform, and manage effective requirements interviews and workshops - Use informational and active listening to capture hidden requirements The presented material is based on our experience gained in consulting contracts with organizations of - every size, from small businesses to multi-nationals and governments. These topics are the core of extensive instructor-led training programs we have presented to tens of thousands of people around the world. As a value add-on, many of the presented ideas are not limited to IT projects; they can improve the outcomes of all of your personal and professional endeavors. You will learn how to: - Identify potential stakeholders - Manage the requirements elicitation process - Track progress toward requirements completion - Define and analyze business problems to ferret out hidden requirements - Facilitate effective requirements brainstorming sessions - Use 10 critical questions to initiate the WHO WILL BENEFIT FROM READING THIS BOOK?

Writing Effective User Stories

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.

How to Write Effective Requirements for IT – Simply Put!

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.
