WHAT IS THIS BOOK ABOUT? Functional and Non-functional Requirements Can Make or Break Your Project Defining solution-level requirements (aka functional and non-functional requirements) is a core competency for anyone in an organization responsible for defining future Information Technology (IT) applications. In this book you will learn simple and repeatable techniques for extracting solution-level specifications from business and stakeholder requirements that are expressed in complete sentence form. My co-author, Angela, and I have used these techniques on hundreds of IT projects around the globe and we know the value each provides. Using these approaches will improve your ability to identify and document requirements at the level of detail that solution providers (vendors or developers) need to deliver the right technology for their organization. The presented techniques will work on any set of well-expressed requirement statements. However, they were specifically designed for and work best with requirement statements that follow the “Rules for Writing Effective Requirements” that we present in our book “How to Write Effective Requirements for IT – Simply Put!”. Regardless of your job title or role, if you are involved in defining future business solutions, this book will help you communicate your business needs to solution providers. It will reduce the potential for misunderstandings that undermine IT’s ability to deliver the right technology for the business. 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 online exercises with immediate feedback featuring our recommended resolution and the rationale behind it. 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: - Decompose Business and Stakeholder Requirement Statements to identify Functional and Non-Functional Requirements - Give those responsible for designing, building, and/or buying the solution the kind of information they need to make the decisions that are right for the business - Identify Informational, Performance, and Constraining Requirements from a list of Functional Requirements - Document and manage Business, Stakeholder, Functional and Non-Functional Requirements - Capture and clarify Business Rules and External Constraints that mandate limits to the delivered solution - Develop measurable Solution Requirements that facilitate End-User Acceptance Testing 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!

WHAT IS THIS BOOK ABOUT? 7 Ways to Improve Your Requirements Elicitation Skills Getting the right requirements from the right people at the right time for your project is a critical success factor for any IT project. Nearly every study over the past 40 years has pinpointed missing and misunderstood IT requirements as the primary cause of IT project failures and overruns. “Requirements Elicitation Techniques – Simply Put!” presents 7 requirements definition techniques that evolved from our work with customers to meet that specific challenge. This book is a continuation of our Requirements Elicitation series. The previously published book “Requirements Elicitation Interviews and Workshops – Simply Put” deals with soft skills (i.e. how to run a requirements workshop) needed to elicit requirements. The book defines the concept of requirements elicitation and explains why it is necessary. It presents specific business analysis techniques for identifying stakeholders, analyzing relevant business problems, helping stakeholders discover what they need and want the solution to deliver, and a set of key questions you need answered to initiate and manage the elicitation process. Applying these techniques will significantly improve your requirements elicitation outcomes. “Requirements Elicitation Techniques – Simply Put!” will help practicing business analysts, future business analysts, subject matter experts, managers, product owners, project managers, and anyone responsible for getting the right requirements from the right people. 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?

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?

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.

National communications systems (NCS) are critical elements of a government's infrastructure. Limited improvements to the operational behaviors or non- functional requirements (NFR) of NCS have caused issues during national emergencies such as 9/11. NCS contractors play a vital role in the design and support of NCS, and this perspective provides valuable insights. There are three major purposes for this case study: (a) to add to the existing theoretical framework on the issues, (b) to define the scope of these concepts, and (c) to provide strategies for management. Four research questions focus on definition, scope, models, and strategies. The results defined 11 major relationships focused on cost, risk, schedule, communication, and quality perceptions. These results provide a framework for strategic system optimization based on collection and analysis of operational information. Strategies for optimizing NCS, based on these findings, can have a positive social impact by improving operational quality and reducing cost, schedule, and risk impacts, which allows a greater capability for NCS to save lives.
