Research Paper (undergraduate) from the year 1998 in the subject Computer Science - Software, grade: 0, University of Kaiserslautern, language: English, abstract: The first step during the software development, requirements engineering, is very critical because of the high effort (in time and costs) that has to be made to correct mistakes detected later that have been made in this early phase of software life-cycle. In order to support the aim of high-quality software, the goals of requirements engineering are developing a complete as possible specification, providing integrated representation formalisms and accomplishing a common agreement on the specification. The very first activity that has to be passed through is requirements elicitation. There are existing three main problems: the problem of defining the scope, the problem of understanding the users’ needs and the problem of requirements volatility over time. You can follow several heuristics and guidelines to find solutions to these problems. In addition, several techniques and methodologies have been suggested to support the process of requirements elicitation. They differ in several ways: the kind of problem they intend to solve, the methods used for achieving this aim, the kind of people involved, the level of abstraction and precision the requirements have to be formulated in. In this report, a selection of these techniques and methodologies is chosen and they are classified into a classification scheme worked out. The techniques and methodologies can coarsely be divided into four classes: interview-oriented approaches, objective and goal analysis-oriented approaches, viewpoint analysis-oriented approaches, and scenario analysis-oriented approaches. There are others that do not fit into this division, but provide nevertheless help for requirements elicitation. The developed classification scheme highlights the differences between the existing techniques. It should serve as an overview of existing techniques and methods as a guideline for analysts and developers for finding an appropriate method for problems at hand.

Following an introductory chapter that provides an exploration of key issues in requirements engineering, this book is organized in three parts. It presents surveys of requirements engineering process research along with critical assessments of existing models, frameworks and techniques. It also addresses key areas in requirements engineering.

This book constitutes the refereed proceedings of the First International Conference on Intelligent Technologies and Applications, INTAP 2018, held in Bahawalpur, Pakistan, in October 2018. The 68 revised full papers and 6 revised short papers presented were carefully reviewed and selected from 251 submissions. The papers of this volume are organized in topical sections on AI and health; sentiment analysis; intelligent applications; social media analytics; business intelligence;Natural Language Processing; information extraction; machine learning; smart systems; semantic web; decision support systems; image analysis; automated software engineering.

Requirements Engineering and Management for Software Development Projects presents a complete guide on requirements for software development including engineering, computer science and management activities. It is the first book to cover all aspects of requirements management in software development projects. This book introduces the understanding of the requirements, elicitation and gathering, requirements analysis, verification and validation of the requirements, establishment of requirements, different methodologies in brief, requirements traceability and change management among other topics. The best practices, pitfalls, and metrics used for efficient software requirements management are also covered. Intended for the professional market, including software engineers, programmers, designers and researchers, this book is also suitable for advanced-level students in computer science or engineering courses as a textbook or reference.

This is the digital version of the printed book (Copyright © 2005). If you develop software without understanding the requirements, you're wasting your time. On the other hand, if a project spends too much time trying to understand the requirements, it will end up late and/or over-budget. And products that are created by such projects can be just as unsuccessful as those that fail to meet the basic requirements. Instead, every company must make a reasonable trade-off between what's required and what time and resources are available. Finding the right balance for your project may depend on many factors, including the corporate culture, the time-to-market pressure, and the criticality of the application. That is why requirements management—gathering requirements, identifying the "right" ones to satisfy, and documenting them—is essential. Just Enough Requirements Management shows you how to discover, prune, and document requirements when you are subjected to tight schedule constraints. You'll apply just enough process to minimize risks while still achieving desired outcomes. You'll determine how many requirements are just enough to satisfy your customers while still meeting your goals for schedule, budget, and resources. If your project has insufficient resources to satisfy all the requirements of your customers, you must read Just Enough Requirements Management.

Learn proven, real-world techniques for specifying software requirements with this practical reference. It details 30 requirement “patterns” offering realistic examples for situation-specific guidance for building effective software requirements. Each pattern explains what a requirement needs to convey, offers potential questions to ask, points out potential pitfalls, suggests extra requirements, and other advice. This book also provides guidance on how to write other kinds of information that belong in a requirements specification, such as assumptions, a glossary, and document history and references, and how to structure a requirements specification. A disturbing proportion of computer systems are judged to be inadequate; many are not even delivered; more are late or over budget. Studies consistently show one of the single biggest causes is poorly defined requirements: not properly defining what a system is for and what it’s supposed to do. Even a modest contribution to improving requirements offers the prospect of saving businesses part of a large sum of wasted investment. This guide emphasizes this important requirement need—determining what a software system needs to do before spending time on development. Expertly written, this book details solutions that have worked in the past, with guidance for modifying patterns to fit individual needs—giving developers the valuable advice they need for building effective software requirements

You may be wondering if business analysis is the right career choice, debating if you have what it takes to be successful as a business analyst, or looking for tips to maximize your business analysis opportunities. With the average salary for a business analyst in the United States reaching above $90,000 per year, more talented, experienced professionals are pursuing business analysis careers than ever before. But the path is not clear cut. No degree will guarantee you will start in a business analyst role. What's more, few junior-level business analyst jobs exist. Yet every year professionals with experience in other occupations move directly into mid-level and even senior-level business analyst roles. My promise to you is that this book will help you find your best path forward into a business analyst career. More than that, you will know exactly what to do next to expand your business analysis opportunities.
