What principle does DRY stand for in Agile methodology?

1. Do Repeat Yourself

2. Don't Repeat Yourself

3. Do Reduce Yourself

4. Don't Reduce Yourself

The correct answer is: Don't Repeat Yourself

The principle represented by DRY in Agile methodology stands for "Don't Repeat Yourself." This principle emphasizes the importance of reducing duplication of code and other artifacts within a project. The idea is that if a piece of knowledge or logic is repeated in multiple places, it can lead to inconsistencies and increased maintenance efforts. By adhering to the DRY principle, developers create a single source of truth for each piece of information or functionality, which not only simplifies updates and changes but also enhances the overall quality and modularity of the codebase. Promoting this principle encourages teams to refactor and structure their code in a way that avoids duplication, making the system easier to understand and maintain over time. This aligns closely with Agile practices that value collaboration, adaptability, and efficiency in development processes.
