Which two review types are most suitable for safety-critical software components?

The selection of technical review and walk-through as the most suitable review types for safety-critical software components is grounded in the heightened need for meticulous scrutiny and thorough verification inherent to such applications. Safety-critical software often governs systems where failures can result in dire consequences, including loss of life or significant harm to the environment, making it essential to engage in processes that ensure both quality and compliance with safety standards.

Technical reviews are structured and systematic processes that focus on the detailed examination of software artifacts by a group of qualified individuals. This review method allows for in-depth analysis of the code or requirements, fostering discussions that can uncover issues related to safety and functionality before they escalate into critical failures.

Walk-throughs, on the other hand, provide a collaborative approach to reviewing work products. In this format, the author presents the material to peers or stakeholders, allowing them to follow along and provide feedback. This interactive process encourages knowledge sharing and highlights any safety concerns that might not have been identified through individual study. It also facilitates the identification of issues related to safety as participants can openly discuss potential hazards and suggest mitigative actions.

In the context of safety-critical software, the ability to collaboratively scrutinize and collectively validate the components greatly enhances the likelihood of identifying and mitigating risks early in the development
