# Design Patterns

By implementing common game programming design patterns in your Unity project, you can efficiently build and maintain a clean, organized, and readable codebase. Design patterns not only reduce refactoring and the time spent testing, but they also speed up onboarding and development processes, contributing to a solid foundation that can be used to grow your game, development team, and business.

Think of design patterns not as finished solutions you can copy and paste into your code, but as extra tools that can help you build larger, scalable applications when used correctly.
