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!

A Data Flow Diagram (DFD) is a phenomenal tool for visualizing and analyzing dependencies and interactions amongst manual and automated business processes. In today's wired world, software applications often take center stage in optimizing workflow and increasing productivity. Unfortunately, the process of delivering the right software to the right people at the right time is challenging to say the least. 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. Data Flow Diagrams - Simply Put! explains WHAT a DFD is, WHY you need one, and HOW to create it. 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. Specifically, Data Flow Diagrams - Simply Put! explains and demonstrates the answers to these questions: What is a Data Flow Diagram (DFD) and what does it do for you? What is the difference between a Rigorous Physical Process Model and a Context-Level DFD? What symbols can I use on each type of diagram? What is the business value of doing exploding or levelling a DFD What is a simple approach for drilling down into a process? How can I show the 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 detailed process specifications offer? How can I express detailed specifications for processes and data? What is "metadata" and why do you need it? Why should I draw a Data Flow Diagram? What does a fully balanced DFD look like? What value does a DFD fragment provide? About the Authors Angela and Tom Hathaway have authored and delivered hundreds of training courses and publications to thousands of business analysts around the world. They have facilitated numerous requirements discovery sessions for information technology projects under a variety of acronyms (JAD, ASAP, JADr, JRP, RGW, etc.). Based on their personal journey and experiences reported by their students, they recognized how much anyone can benefit from a basic understanding of what Data Flow Diagrams are, what they represent, who needs them, and how to get started creating them. Angela's and Tom's mission is to allow anyone, anywhere access to simple, easy-to-learn techniques by sharing their experience and expertise in their training seminars, blog posts, books, video courses, KnowledgeKnuggets(tm), and public presentations.

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?
