“…Two related studies, [56] and [59], focused on applying Agile methodologies in complex, interdisciplinary, and technology-driven environments. The first study, by Marques et al, demonstrates the use of a modified Scrum framework called Q-Scrum within Interdisciplinary Problem-Based Learning (IPBL) at Brazil's Aeronautics Institute of Technology (ITA) [56]. Over seven years, Q-Scrum has been implemented in four courses, teaching students to create safety-critical prototypes while complying with software standards.…”

“…Although still in the research phase and tested primarily in academic settings, CARD-RM aims to blend Agile practices with DO-178C compliance. Additional studies, such as [56] and [59] investigated the application of Agile methods in complex, interdisciplinary environments. [56], for example, showcases the use of a modified Scrum framework, Q-Scrum, in IPBL.…”

“…However, even with these tools, managing traceability remains a challenge, especially since manual verification of documents is often required by certification regulations when using uncertified tools. An alternative approach was explored by [56], [59], and [60], who investigated modelbased methods combined with Agile practices. Marques et al describes the implementation of a modified Scrum framework, Q-Scrum, for developing safety-critical prototypes in compliance with software standards [56].…”

Domain-specific standards and documents heavily regulate safety-critical systems. One example is the DO-178C standard for aerospace, which guides organizations to achieve system safety and evidence for their certification. Under such regulated contexts, most organizations use traditional development processes, in contrast to the massive adoption of Agile in the software industry. Among other benefits, Agile methods promise faster delivery and better flexibility to address customer needs. Adopting Agile methods and practices are possible in aerospace because the DO-178C standard does not prescribe concrete software development methods. In spite of that, Agile development is not used in DO-178C contexts. To help change that, our research aims to understand whether and how organizations engineering safety-critical software systems for aerospace may benefit from Agile methods and practices. We analyzed the DO-178C standard and confirm that it is compatible with Agile methods. Then, we present a systematic literature mapping of adopting Agile in software development for aerospace, where we identified significant concerns, recurrent issues, and several challenges. Some real industry aerospace projects provided us with important data and the perspective of domain experts about the pros and cons of Agile methods in this context. We conclude by proposing an agenda of research opportunities to improve safety-critical software development towards agility that we consider worthy of further research, application and confirmation in wider contexts.
