Agile Development: A Flexible Approach to Software Development
What is Agile Development?
Agile development is a software development methodology that emphasizes iterative development, collaboration, and flexibility. Unlike traditional waterfall methodologies, Agile focuses on delivering working software in short iterations, known as sprints. This approach allows for continuous adaptation to changing requirements and priorities.
Core Principles of Agile Development
Agile development is guided by a set of core principles:
- Individuals and Interactions Over Processes and Tools: Prioritize effective communication and collaboration among team members.
- Working Software Over Comprehensive Documentation: Focus on delivering functional software rather than extensive documentation.
- Customer Collaboration Over Contract Negotiation: Work closely with customers to ensure their needs are met.
- Responding to Change Over Following a Plan: Be adaptable to changing requirements and priorities.
Agile Methodologies
Several popular Agile methodologies have emerged, each with its own specific approach:
