**Iterative methodology** is a software development approach that emphasizes incremental and repetitive progress. It involves **breaking down a project into smaller cycles or iterations**, each of which results in a functional part of the software. After each iteration, stakeholders can review the work and provide feedback, which is then used to refine and enhance subsequent iterations. 

## Key principles
1. **Incremental Development**: The project is divided into small, manageable parts or iterations. Each iteration adds new functionality or refines existing features;
2. **Feedback and Review**: Stakeholders, including users, product owners, and developers, regularly review the work completed in each iteration. Feedback guides further development;
3. **Flexibility**: Iterative methodologies are adaptable to changing requirements, allowing adjustments to be made at the end of each iteration based on feedback and evolving project needs;
4. **Continuous Improvement**: The goal is to refine and enhance the software with each iteration, making it more functional, reliable, and user-friendly over time.
