## Definition

a standard solution to a common problem that happens often in software development. It is like a blueprint or a template that you can follow to write better code.

For teachers: a general, reusable solution to a commonly occurring problem within a given context in software design. It serves as a template for how to solve a problem that can be used in many different situations rather than a finished design that can be transformed directly into code.

## Examples

- The developer used a design pattern to organize the new app.
- By implementing a well-known design pattern, the engineering team ensured that the new module would be easy for future hires to understand.
- While applying a specific design pattern can significantly improve code maintainability, over-engineering a simple system with unnecessary patterns can lead to excessive complexity and reduced performance.

## Usage notes

- Commonly used in the plural ('design patterns') when discussing software architecture or engineering principles.
