Agile software development is an iterative and incremental approach to software development that focuses on delivering value to customers quickly and efficiently.

Agile software development is a product management methodology that focuses on delivering high-quality software quickly and efficiently. It emphasizes collaboration between teams, customer feedback, and iterative development cycles. Agile product management involves breaking down large projects into smaller tasks that can be completed in short sprints. This allows teams to focus on delivering value to customers quickly and efficiently. Agile product management also encourages teams to continuously review their progress and make adjustments as needed. This helps ensure that the final product meets customer needs and expectations. Additionally, Agile product management encourages teams to embrace change and adapt quickly to new requirements or customer feedback. Finally, Agile product management emphasizes communication between stakeholders, which helps ensure that everyone is on the same page throughout the development process.

1. Scrum: Scrum is an iterative and incremental agile software development framework for managing product development. It defines "a flexible, holistic product development strategy where a development team works as a unit to reach a common goal", challenges assumptions of the "traditional, sequential approach" to product development, and enables teams to self-organize by encouraging physical co-location or close online collaboration of all team members, as well as daily face-to-face communication among all team members and disciplines in the project. 2. Kanban: Kanban is an agile software development methodology that focuses on visualizing workflows and limiting work in progress (WIP). It is based on the idea that teams should only take on as much work as they can handle at any given time, and that tasks should be completed before new ones are started. This helps teams stay focused on their current tasks and prevents them from getting overwhelmed by too many tasks at once. 3. Extreme Programming (XP): Extreme Programming (XP) is an agile software development methodology that emphasizes communication, simplicity, feedback, and courage. XP encourages teams to break down complex problems into smaller pieces that can be solved quickly and efficiently. It also encourages teams to use automated tests to ensure quality throughout the process.
