Safety-Critical Systems (SCS) are increasingly present in people's daily activities. In the means of transport, in medical treatments, in industrial processes, in the control of air, land, maritime traffic, and many other situations, we use and depend on SCS. The requirements engineering of any system is crucial for the proper development of the same, and it becomes even more relevant for the development of SCS. Requirements Engineering is a discipline that focuses on the development of techniques, methods, processes, and tools that assist in the design of software and systems, covering the activities of elicitation, analysis, modeling and specification, validation, and management of requirements. The complete specification of system requirements establishes the basis for its architectural design. It offers a description of the functional and quality aspects that should guide the implementation and system evolution. In this book, we discuss essential elements of requirements engineering applied to SCS, such as the relationship between safety/hazard analysis and requirements specification, a balance between conservative and agile methodologies during SCS development, the role of requirements engineering in safety cases, and requirements engineering maturity model for SCS. This book provides relevant insights for professionals, students, and researchers interested in improving the quality of the SCS development process, making system requirements a solid foundation for improving the safety and security of future systems.

This book addresses the development of safety-critical software and to this end proposes the SafeScrum® methodology. SafeScrum® was inspired by the agile method Scrum, which is extensively used in many areas of the software industry. Scrum is, however, not intended or designed for use with safety-critical systems; hence the authors propose guidelines and additions to make it both practically useful and compliant with the additional requirements found in safety standards. The book provides an overview of agile software development and how it can be linked to safety and relevant safety standards. SafeScrum® is described in detail as a useful approach for reaping the benefits of agile methods, and is intended as a set of ideas and a basis for adaptation in industry projects. The book covers roles, processes and practices, and documentation. It also includes tips on how standard software process tools can be employed. Lastly, some insights into relevant research in this new and emerging field are provided, and selected real-world examples are presented. The ideas and descriptions in this book are based on collaboration with the industry, in the form of discussions with assessment organizations, general discussions within the research fields of safety and software, and last but not least, the authors’ own experiences and ideas. It was mainly written for practitioners in industry who know a great deal about how to produce safety-critical software but less about agile development in general and Scrum in particular.

This book provides professionals and students with practical guidance for the development of safety-critical computer-based systems. It covers important aspects ranging from complying with standards and guidelines to the necessary software development process and tools, and also techniques pertaining to model-based application development platforms as well as qualified programmable controllers. After a general introduction to the book’s topic in chapter 1, chapter 2 discusses dependability aspects of safety systems and how architectural design at the system level helps deal with failures and yet achieves the targeted dependability attributes. Chapter 3 presents the software development process which includes verification and validation at every stage, essential to the development of software for systems performing safety functions. It also explains how the process helps in developing a safety case that can be independently verified and validated. The subsequent chapter 4 presents some important standards and guidelines, which apply to different industries and in different countries. Chapter 5 then discusses the steps towards complying with the standards at every phase of development. It offers a guided tour traversing the path of software qualification by exploring the necessary steps towards achieving the goal with the help of case studies. Chapter 6 highlights the application of formal methods for the development of safety systems software and introduces some available notations and tools which assist the process. Finally, chapter 7 presents a detailed discussion on the importance and the advantages of qualified platforms for safety systems application development, including programmable controller (PLC) and formal model-based development platforms. Each chapter includes case studies illustrating the subject matter. The book is aimed at both practitioners and students interested in the art and science of developing computer-based systems for safety-critical applications. Both audiences will get insights into the tools and techniques along with the latest developments in the design, analysis and qualification, which are constrained by the regulatory and compliance requirements mandated by the applicable guides and standards. It also addresses the needs of professionals and young graduates who specialize in the development of necessary tools and qualified platforms.

Safety-critical devices, whether medical, rail, automotive or industrial are dependent on the correct operation of sophisticated software. Many standards describe how such systems should be designed, built and verified. Developers who previously had to know only how to program devices for their industry must now understand and deploy additional development practices and be prepared to justify their work to external assessors. The third edition of Embedded Software Development for Safety-Critical Systems is about the creation of dependable embedded software. It is written for system designers, implementers and verifiers who are experienced in general embedded software development, but who are now facing the prospect of developing a software-based system for safety-critical applications. In particular, it is aimed at those creating a product that must satisfy one or more of the international standards relating to safety critical applications, including IEC 61508, ISO 26262, EN 50716, UL 4600, ISO 21448, ISO/PAS 8800 or IEC 62304. This book has evolved from a course text used by QNX for a three-day training module on building embedded software for safety-critical systems Although it describes open source tools for most applications, it also provides enough information for you to seek out commercial vendors if that’s the route you decide to pursue. All of the techniques described in this book may be further explored through several hundred references to articles that the author has personally found helpful as a professional software developer. Almost all of these references are available for free download.

The safety case (SC) is one of the railway industry’s most important deliverables for creating confidence in their systems. This is the first book on how to write an SC, based on the standard EN 50129:2003. Experience has shown that preparing and understanding an SC is difficult and time consuming, and as such the book provides insights that enhance the training for writing an SC. The book discusses both "regular" safety cases and agile safety cases, which avoid too much documentation, improve communication between the stakeholders, allow quicker approval of the system, and which are important in the light of rapidly changing technology. In addition, it discusses the necessity of frequently updating software due to market requirements, changes in requirements and increased cyber-security threats. After a general introduction to SCs and agile thinking in chapter 1, chapter 2 describes the majority of the roles that are relevant when developing railway-signaling systems. Next, chapter 3 provides information related to the assessment of signaling systems, to certifications based on IEC 61508 and to the authorization of signaling systems. Chapter 4 then explains how an agile safety plan satisfying the requirements given in EN 50126-1:1999 can be developed, while chapter 5 provides a brief introduction to safety case patterns and notations. Lastly, chapter 6 combines all this and describes how an (agile) SC can be developed and what it should include. To ensure that infrastructure managers, suppliers, consultants and others can take full advantage of the agile mind-set, the book includes concrete examples and presents relevant agile practices. Although the scope of the book is limited to signaling systems, the basic foundations for (agile) SCs are clearly described so that they can also be applied in other cases.
