How do design principles affect software quality?

Design principles are fundamental guidelines that help create software that is not only functional but also maintainable, scalable, and user-friendly. They influence aspects like code readability, modularity, and overall user experience.

Can you give examples of specific design principles?

Sure! Some key design principles include SOLID principles, DRY (Don't Repeat Yourself), KISS (Keep It Simple, Stupid), and YAGNI (You Aren't Gonna Need It). Each of these helps improve software quality in different ways.

How do these principles improve maintainability?

By following these principles, developers create code that is easier to understand and modify. For instance, SOLID principles promote single responsibility and open-closed design, making it simpler to update or extend functionality without introducing bugs.

What role does user experience play in software quality?

User experience is crucial as it directly impacts user satisfaction and engagement. Good design principles ensure that the software is intuitive and meets user needs, which in turn enhances overall quality.
