In embedded systems, the quality of code is crucial for long term reliability and efficiency. The Clean Code principles, as outlined in Robert C. Martin’s influential book Clean Code, are widely used in general software development and can significantly enhance embedded C development. This article explores how these principles can be applied to embedded C, drawing on extensive experience to improve code readability, reduce technical debt, and lower costs over the system’s lifetime. Whether you’re a developer or a manager, this guide offers practical insights into integrating Clean Code into your embedded systems projects.

Manchmal erreicht ein Software-Projekt einen Punkt, an dem die Weiterentwicklung fast zum Stillstand kommt. Features werden nur noch mühsam implementiert, und die Kosten für Änderungen explodieren. Genau an diesem Punkt stand unser Kunde, als er uns, Urs Fässler von iQiliO und Peter Gfader von Beyond Agility, mit einem Architektur-Review beauftragte. Ziel war es, den Zustand der Software objektiv zu bewerten und eine Empfehlung abzugeben: Soll die bestehende Software weiterentwickelt oder komplett neu geschrieben werden?

As software touches every part of life, people expect higher standards for quality, security, and reliability. The Cyber Resilience Act (CRA) reflects this shift - a necessary response to past industry mistakes. Rather than resisting, we can use this regulation to improve our practices. Here’s why regulation is necessary, how we reached this point, and how we can use it to create better software.

The CRA mandates stringent cybersecurity requirements for digital products, ranging from vulnerability management and regular updates to security-by-design principles. Manufacturers are tasked with ensuring that their products remain secure throughout their lifecycle, providing ongoing updates, and managing vulnerabilities proactively. The agile development approach, characterized by iterative cycles, cross-functional collaboration, and continuous integration, is ideally suited to meet these requirements. Agile practices enable teams to quickly adapt to new regulatory demands, implement security measures efficiently, and deliver high-quality, secure software. This article outlines the key aspects of agile development that align with CRA compliance and demonstrates how organizations can leverage agility to meet their obligations under the CRA.

Dieses paradoxe Phänomen tritt häufig in der Softwareentwicklung auf. Entwickler stehen unter Zeitdruck und sehen sich gezwungen, schnelle Lösungen zu implementieren, anstatt sich Zeit zu nehmen, diese zu planen und so zu implementieren, dass die Software nachhaltig erweiterbar ist. Dies führt zu schlechter Codequalität und unzureichender Testabdeckung, die später mehr Zeit und Ressourcen erfordern, um sie zu beheben. Der Versuch, Zeit zu sparen, indem man an der Qualität spart, endet in einem viel längeren Entwicklungszyklus.
