Why SOLID Still Matters: Timeless Principles in a Modern Software World
In this episode of The Agile Engineering Deep Dive, Alessandro Guida revisits the SOLID principles and explores why they still matter in modern software engineering.
In a world of microservices, cloud platforms, and AI-assisted development, SOLID is sometimes seen as outdated or overly focused on code-level concerns. Yet the underlying challenges of software engineering have not changed: managing complexity, reducing coupling, and enabling systems to evolve safely over time.
This episode reflects on how principles like Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion extend far beyond classes and objects - shaping APIs, services, architecture, and organizational resilience.
The goal is not to promote dogma or rigid rules, but to show how timeless design principles help teams build software that remains understandable, testable, and adaptable long after tools, frameworks, and original developers have changed.
