In recent years, there has been an increasing interest and growing use of agile development methods when developing safety-critical systems. This interest is motivated by the need to shorten time-to-market, reduce costs, improve quality, and to support the paradigm of continuous development and depl...

While agile methods have had a great uptake and impact in software engineering, managing non‑functional qualities still seems to be a challenge. We focus on the scalability of software systems and how this critical quality can be managed and controlled, while still benefiting from the advantages of ...

Architectural technical debt can be generated by changes in the business and the environment of an organization. In this paper, we emphasize the change in scalability requirements due to new regulations. Scalability is the ability of a system to handle an increased workload. For complex systems that...

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...

Scalability engineering is currently not well integrated into agile development techniques. This paper extends agile development techniques so that scalability can be handled in an incremental and iterative development process. By scalability we mean the ability of a system to handle increasing work...

Software firms participate in an ecosystem as a part of their innovation strategy to extend value creation beyond the firm’s boundary. Participation in an open and independent environment also implies the competition among firms with similar business models and targeted markets. Hence, firms need to...

Agile development of safety-critical software has evolved from an early conceptual idea to, presently, an approach that is gaining uptake in the industry. As we now get more and more experience we also discover new challenges and related ideas that needs further investigation. The third internationa...
