Requirements engineering tasks have become increasingly complex. In order to ensure a high level of knowledge and competency among requirements engineers, the International Requirements Engineering Board (IREB) developed a standardized qualification called the Certified Professional for Requirements Engineering (CPRE). The certification defines the practical skills of a requirements engineer on various training levels. This book is designed for self-study and covers the curriculum for the Certified Professional for Requirements Engineering Foundation Level exam as defined by the IREB. The 2nd edition has been thoroughly revised and is aligned with the curriculum Version 2.2 of the IREB. In addition, some minor corrections to the 1st edition have been included. About IREB: The mission of the IREB is to contribute to the standardization of further education in the fields of business analysis and requirements engineering by providing syllabi and examinations, thereby achieving a higher level of applied requirements engineering. The IRE Board is comprised of a balanced mix of independent, internationally recognized experts in the fields of economy, consulting, research, and science.The IREB is a non-profit corporation.

This Open Access book presents the results of the "Collaborative Embedded Systems" (CrESt) project, aimed at adapting and complementing the methodology underlying modeling techniques developed to cope with the challenges of the dynamic structures of collaborative embedded systems (CESs) based on the SPES development methodology.In order to manage the high complexity of the individual systems and the dynamically formed interaction structures at runtime, advanced and powerful development methods are required that extend the current state of the art in the development of embedded systems and cyber-physical systems. The methodological contributions of the project support the effective and efficient development of CESs in dynamic and uncertain contexts, with special emphasis on the reliability and variability of individual systems and the creation of networks of such systems at runtime.The project was funded by the German Federal Ministry of Education and Research (BMBF), and the case studies are therefore selected from areas that are highly relevant for Germany’s economy (automotive, industrial production, power generation, and robotics). It also supports the digitalization of complex and transformable industrial plants in the context of the German government's "Industry 4.0" initiative, and the project results provide a solid foundation for implementing the German government's high-tech strategy "Innovations for Germany" in the coming years.

This book constitutes the thoroughly refereed proceedings of five international workshops held in Thessaloniki, Greece, in conjunction with the 26th International Conference on Advanced Information Systems Engineering, CAiSE 2014, in June 2014.The 24 full and eight short papers were carefully selected from 63 submissions.The five workshops were the First International Workshop on Advanced Probability and Statistics in Information Systems (APSIS), the First International Workshop on Advances in Services Design Based on the Notion of Capability, the Second International Workshop on Cognitive Aspects of Information Systems Engineering (COGNISE), the Third Workshop on New Generation Enterprise and Business Innovation Systems (NGEBIS), and the 4th International Workshop on Information Systems Security Engineering (WISSE).

This book provides a comprehensive introduction into the SPES XT modeling framework. Moreover, it shows the applicability of the framework for the development of embedded systems in different industry domains and reports on the lessons learned. It also describes how the SPES XT modeling framework can be tailored to meet domain and project-specific needs.The book is structured into four parts: Part I     “Starting Situation” discusses the status quo of the development of embedded systems with specific focus on model-based engineering and summarizes key challenges emerging from industrial practice.Part II    “Modeling Theory” introduces the SPES XT modeling framework and explains the core underlying principles. Part III   “Application of the SPES XT Framework” describes the application of the SPES XT modeling framework and how it addresses major industrial challenges. Part IV   “Evaluation and Technology Transfer” assess the impact of the SPES XT modeling framework and includes various exemplary applications from automation, automotive, and avionics. Overall, the SPES XT modeling framework offers a seamless model-based engineering approach. It addresses core challenges faced during the engineering of embedded systems. Among others, it offers aligned and integrated techniques for the early validation of engineering artefacts (including requirements and functional and technical designs), the management of product variants and their variability, modular safety assurance and deployment of embedded software.

Since 1995, a series of projects on the topic of software product family engineering were done, ARES, Praise, ESAPS, CAF+, and FAMILIES. These projects originated from industry needs to improve software engineering performance by organizing the development in families. The results have been implemented in several large industries and involve a radical shift in software construction, and production.

With SPLC 2005 we celebrated the formation of a new conference series, the International Software Product Line Conference (SPLC) which results from the “uni?cation” of the former series of three SPLC (Software Product Line) Con- rences launched in 2000 in the USA, and the former series of ?ve PFE (Product Family Engineering) Workshops started in 1996 in Europe. SPLC is nowthe premier forum for the growing community of software p- duct line practitioners, researchers, and educators. SPLC o?ers a unique - portunity to present and discuss the most recent experiences, ideas, innovations, trends,andconcernsintheareaofsoftwareproductlineengineering andtobuild aninternationalnetworkofproductlinechampions.AninternationalSPLCSt- ring Committee has been established and it is the wish of this committee that from 2005 on, the SPLC conference will be held yearly in Europe, America, or Asia. The technical program of SPLC 2005 included. – two keynotes from David Weiss (Avaya, USA) and Jan Bosch (Nokia, F- land), both leading experts with academic and industrial insights; – 17 full and 3 short research papers organized around the following themes: feature modeling, re-engineering, strategies, validation, scoping and arc- tecture, and product derivation; – eight experience reports describing commercial application of product line practices; – two panels focused on special topics in product line practice and product line research; – tool demonstrations; – aHallofFamesessionthatcontinuedtheSPLCtraditioninaslightlyrevised format. In addition, the technical program was preceded by a tutorial and workshop day that included ten half-day tutorials presented by well-recognized experts and ?ve workshops on speci?c areas of product line research.

Today it is almost impossible to remember what life was like with no computer, no mobile phone, and no Internet for accessing information, performing tra- actions or exchanging emails and data. New technology is bringing wave after wave of new bene?ts to daily life: organisations are doing business with each other via the Internet; people are ?lling in tax declarations online and booking their next vacation through the Internet. In general we are all progressively - ing (and dependent on) software and services running on computers, connecting mobile phones and other devices, and exchanging information on the Internet. People like to shop around and exercise choice. So do businesses and public administrations. Today they can buy a complete software package that best suits their needs, even though they may never use some of the tools it o?ers, or other desirable tools are not available. In the future they may no longer have to compromise on choice. Alternative approaches like “Software as a Service” and “Computing Resources as a Service” are emerging. Software is provided on-line as a service when and where it is needed, and the same for computing resources needed to run software. Such an approach allows individuals and organisations totapintoande?ectivelyharnesstheimmensewealthofinformation,knowledge and analytical resources when they need them, paying only for what they use.

I. Software Product Line Engineering Are you interested in producing software products or software-intensive systems at lower costs, in shorter time, and with higher quality? If so, you are holding the right book in your hands. Software product line engineering has proven to be the methodology for Higher quality, lower developing a diversity of software products and software-intensive systems cost, and shorter at lower costs, in shorter time, and with higher quality. Numerous reports development times document the significant achievements and experience gained by introducing software product lines in the software industry. Chapter 21 of this book summarises several cases. Concerning the terminology, there is an almost synonymous use of the terms Software product line “software product family” and “software product line”. Whereas in Europe vs. software product the term software product family is used more often, in North America the family term software product line is used more frequently. This is, among other things, reflected in the names of the two former conference series (the so- ware product line conference series, started in 2000 in the USA, and the product family engineering (PFE) workshop series, started in 1996 in Europe) which were merged in 2004 to form the leading software product line conference (SPLC) series. In this book, we use the term software product line.

Requirements engineering is the process of eliciting individual stakeholder requirements and needs and developing them into detailed, agreed requirements documented and specified in such a way that they can serve as the basis for all other system development activities.

This textbook provides a comprehensive and well-structured introduction to the fundamentals, principles, and techniques of requirements engineering (RE). It presents approved techniques for eliciting, negotiating, and documenting as well as validating, and managing requirements for software-intensive systems. The various aspects of the process and the techniques are illustrated using numerous examples based on extensive teaching experience and industrial collaborations. The book is structured in five parts. Part I “Fundamentals and Framework” provides a comprehensive introduction to the fundamentals of RE, illustrates why it is a critical success factor for any software development project, and describes different ways of implementing it in an organization and its role in different software engineering process models. Part II “Requirements Engineering Context” explains the essential role and influence of the RE context on system requirements, defines basic terms,and introduces the concept of context perspectives to support context consideration. Part III “Core Activities” describes requirements elicitation, documentation, and negotiation and conflict resolution strategies. Part IV “Requirements Artefacts” explains the management of goals, scenarios, and solution-oriented requirements, including methodologies like i* and KAOS. Eventually, Part V “Cross-Sectional Activities” details four validation and three management activities. This second edition of Pohl’s widely used and trusted textbook provides a considerable number of updates, places a stronger focus on the consideration of the context, puts a stronger emphasis on conflict resolution, and includes new, expanded and revised techniques.The presentation aims at professionals, students, and lecturers in systems and software engineering or business applications development. Professionals such as project managers, software architects, systems analysts, and software engineers will benefit in their daily work from the didactically well-presented combination of validated procedures and industrial experience. Students and lecturers will appreciate the comprehensive description of sound fundamentals, principles, and techniques, which is completed by a huge, commented list of references for further reading. Lecturers will find additional teaching material on the book’s website, www.requirements-book.com.
