Learn how to create good requirements when designing hardware and software systems. While this book emphasizes writing traditional “shall” statements, it also provides guidance on use case design and creating user stories in support of agile methodologies. The book surveys modeling techniques and various tools that support requirements collection and analysis. You’ll learn to manage requirements, including discussions of document types and digital approaches using spreadsheets, generic databases, and dedicated requirements tools. Good, clear examples are presented, many related to real-world work the author has done during his career. Requirements Writing for System Engineeringantages of different requirements approaches and implement them correctly as your needs evolve. Unlike most requirements books, Requirements Writing for System Engineering teaches writing both hardware and software requirements because many projects include both areas. To exemplify this approach, two example projects are developed throughout the book, one focusing on hardware and the other on software. This book Presents many techniques for capturing requirements. Demonstrates gap analysis to find missing requirements. Shows how to address both software and hardware, as most projects involve both. Provides extensive examples of “shall” statements, user stories, and use cases. Explains how to supplement or replace traditional requirement statements with user stories and use cases that work well in agile development environments What You Will Learn Understand the 14 techniques for capturing all requirements. Address software and hardware needs; because most projects involve both. Ensure all statements meet the 16 attributes of a good requirement. Differentiate the 19 different functional types of requirement, and the 31 non-functional types. Write requirements properly based on extensive examples of good ‘shall’ statements, user stories, and use cases. Employ modeling techniques to mitigate the imprecision of words. Audience Writing Requirements teaches you to write requirements the correct way. It is targeted at the requirements engineer who wants to improve and master his craft. This is also an excellent book from which to teach requirements engineering at the university level. Government organizations at all levels, from Federal to local levels, can use this book to ensure they begin all development projects correctly. As well, contractor companies supporting government development are also excellent audiences for this book.

Alistair Cockburn beschreibt ausführlich, was Uses Cases sind, welche Bestandteile hineingehören und wie man sie strukturieren sollte. Besonders nützlich sind seine Erörterungen, wie man mit großen Mengen von Use Cases umgeht. Im zweiten Teil seines Buchs geht Cockburn auf verschiedene praktische Probleme ein. Es geht um Fragen wie "Woran erkennen wir, dass wir fertig sind?" oder "Wie fügen sich Use Cases in den Gesamtprozess ein?". Im dritten Teil werden die wichtigsten Themen noch einmal als knappe Referenz zusammengefasst.

Nicht wenige Software-Projekte erreichen ihre gesteckten Ziele nicht, da bereits in ihrer Anfangsphase Anforderungen an die Software nicht gründlich genug analysiert und dokumentiert wurden. Oft wird auch vernachlässigt, dass Softwareentwicklung genauso viel mit Kommunikation, wie mit eigentlicher Entwicklungsarbeit zu tun hat. An diesem Punkt setzt dieser Klassiker der Softwareentwicklungsliteratur an, in dem überzeugend präsentiert wird, warum die Erhebung, Zusammenstellung und das Managen von Software Requirements essentiell für erfolgreiche Projekte ist und mit welchen erprobten Mitteln diese Aufgaben am besten zu meistern sind. Karl Wiegers zeigt damit, wie Requirements-Analysten, Projektleiter, aber auch alle Programmierer und Designer, die Anforderungen der Kunden umsetzen müssen, Produktivität, Termintreue, Kundenzufriedenheit und Wartungs- und Supportkosten mit dem im Buch beschriebenen Praktiken drastisch verbessern können. - Realistische Erwartungen für Funktionalität und Qualität setzen - Geschäftsregeln in die Anwendungsentwicklung integrieren - Anwendungsfälle zur Definition von Benutzeranforderungen verwenden - Unausgesprochene und wechselnde Requirements identifizieren und managen - Revisionen einschränken und damit Kosten sparen - Besser Software produzieren

Solid requirements engineering has become increasingly essential to on-time and on-budget delivery of software and systems projects. As more engineering programs make it a mandatory part of their curricula, students and working engineers require significant training to master the field, especially the complicated emerging ancillary software tools vital to the requirements engineering process. With a focus on software-intensive systems, Requirements Engineering for Software and Systems provides a probing and comprehensive review of recent developments in intelligent systems, soft computing techniques, and their diverse applications in manufacturing. Topics covered can be applied to the requirements engineering practices for: Advanced production machines and systems Collaborative and responsive manufacturing systems Digital manufacturing E-manufacturing E-business and virtual enterprises Fit manufacturing Human machine interfaces Innovative design technologies Intelligent and competitive manufacturing Intelligent planning and scheduling systems Mechatronics and MEMS Micro and nano manufacturing Production automation and control Reconfigurable manufacturing systems Sustainable manufacturing systems Robotics To illustrate key ideas associated with requirements engineering, the text presents three common example systems: an airline baggage handling system, a point-of-sale system for one location of a large pet store chain, and a system for a smart home in which one or more PCs control various aspects of the home’s functions. The selected systems encompass a wide range of applications—from embedded to organic, for both industrial and consumer uses.

This book focuses on various topics related to engineering and management of requirements, in particular elicitation, negotiation, prioritisation, and documentation (whether with natural languages or with graphical models). The book provides methods and techniques that help to characterise, in a systematic manner, the requirements of the intended engineering system. It was written with the goal of being adopted as the main text for courses on requirements engineering, or as a strong reference to the topics of requirements in courses with a broader scope. It can also be used in vocational courses, for professionals interested in the software and information systems domain. Readers who have finished this book will be able to: - establish and plan a requirements engineering process within the development of complex engineering systems; - define and identify the types of relevant requirements in engineering projects; - choose and apply the most appropriate techniques to elicit the requirements of a given system; - conduct and manage negotiation and prioritisation processes for the requirements of a given engineering system; - document the requirements of the system under development, either in natural language or with graphical and formal models. Each chapter includes a set of exercises.
