To keep software architecture flexible and stable, focus on creating a modular structure, using design patterns that allow for easy updates, and keeping components loosely connected. This way, it can adapt to future changes without breaking.

To ensure software architecture remains flexible yet stable, focus on modular design principles. Break the system into smaller, independent components or microservices, allowing for easier updates and scalability without disrupting the entire system. Embrace design patterns like dependency injection and interfaces to decouple components, making the architecture adaptable to changes. Use version control and clear documentation to maintain stability while encouraging innovation. Prioritize continuous integration and automated testing to catch issues early, ensuring a stable core while enabling future adaptability.

Make sure that you implement classes and comment on all of your code. By adding classes, you create code that can be reused based on need, and the comments will help to explain all uses of code to future developers. Another useful tactic is writing docs for your programs and following a certain code structure that would be either company defined, or defined in the design docs.

Modular Design: Break the system into smaller, independent modules or services that can be developed, tested, and deployed separately.

Modular Design: Use a modular architecture that breaks the system into smaller, independent components. This allows for easier updates and replacements without affecting the entire system.
