The podcast discusses the applicability of DevOps principles in embedded systems development. It explores the challenges of implementing Agile and DevOps, proving quality in agile development, applying DevOps to embedded systems, updating embedded systems, and embracing Agile in safety-critical industries.
DevOps and Agile methodologies are applicable to embedded systems development despite skepticism, as they offer benefits such as fast feedback and smooth workflow.
Coordinating workflows and aligning release cycles between hardware and software teams enables faster feedback, early problem identification, and increased confidence in the development process.

DevOps and Agile in Embedded Systems Development
DevOps and Agile methodologies are beneficial and applicable to embedded systems development despite some skepticism. DevOps, in essence, is a continuation of good engineering practices adapted to new tools and ways of working. While there are debates about Agile practices within the medical devices world, the importance of fast feedback and smooth workflow can't be denied. The challenge lies in aligning different teams and disciplines in the embedded systems project, such as mechanical engineers, electrical engineers, and software engineers. By embracing fast iterations, clear communication, and focusing on quality and risk management, embedded systems development can be more efficient and successful.
The Role of Hardware Iterations in Agile
Hardware iterations have a slower cadence compared to software iterations due to longer lead times and manufacturing processes. However, a fixed release cycle for hardware revisions can still be implemented, which allows for clear expectations and alignment between hardware and software teams. By coordinating their workflows and aligning release cycles, teams can benefit from faster feedback, uncover potential problems earlier, and build confidence in their processes. Agile principles, such as short iterations and continuous improvement, can still be applied effectively in the context of embedded systems development.
Applying Agile and DevOps in Safety Critical Industries
Even in safety critical industries, Agile and DevOps principles can be successfully applied. While software hardware interacts directly with hardware, it doesn't pose a fundamental obstacle. Instead, it requires an understanding of compliance and regulatory requirements. Companies must balance fast iterations with safety and prove the quality of their work to regulators. The focus should be on smooth workflow, quick feedback, and involving regulators earlier in the process, rather than waiting until the end. There may also be a need to consider how to effectively communicate updates to users in safety critical applications, where users may not be trained professionals.
The Importance of Mindset and Culture in Agile Embedded Development
Agile embedded development requires a proper mindset and culture within an organization. It is not just about adopting specific techniques or tools, but about embracing a mindset that values fast feedback, collaboration, and continuous improvement. The challenge lies in instilling this mindset and overcoming cultural barriers within organizations, particularly in established companies or industries with slower approval processes. However, with discipline and a focus on the core principles of Agile, embedded systems development can become more efficient, uncover and fix defects faster, and ultimately deliver higher quality products.
Some people (apparently) think that DevOps principles don't make sense for embedded systems development.
