What is Agile Methodology?
- It's an approach where a project is divided into multiple parts, and each part is developed individually.
- This process involves iterations in every part of the project and constant collaboration with stakeholders.
- The software development and testing process are conducted parallelly.
- It is possible to change the requirement because the different blocks are developed independently.
- It supports cross-functional collaborations among the team members.
