Agile Methodology
Agile is a flexible and iterative approach to software development that emphasizes collaboration, customer feedback, and incremental progress. It aims to deliver high-quality, more adaptive, and customer-centric software than traditional methodologies like Waterfall.
Key principles
- Customer Collaboration Over Contract Negotiation: Agile prioritizes working closely with customers and stakeholders to understand their needs and adapt to changing requirements. It values customer feedback and satisfaction;
- Individuals and Interactions Over Processes and Tools: Agile places importance on the people involved in the project and their communication. It values collaboration, face-to-face interactions, and teamwork;
- Working Software Over Comprehensive Documentation: Agile values working software as the primary measure of progress. While documentation is important, it should not impede the development of functional software;
- Responding to Change Over Following a Plan: Agile embraces change and welcomes it as a way to improve the project's outcome. It emphasizes adaptability and the ability to respond to new information and requirements.
| Aspect | Waterfall | Iterative | Agile |
|---|---|---|---|
| Development Approach | Sequential, with distinct phases performed in order. | Incremental and repetitive, with frequent cycles of planning, designing, building, and testing. | Flexible and adaptive, with a focus on collaboration and incremental progress. |
| Flexibility | Low flexibility, changes are difficult and expensive to implement once a phase is completed. | High flexibility, allows for changes and adaptations at the end of each iteration. | High flexibility, welcomes changes and responds to evolving requirements. |
| Stakeholder Involvement | Limited stakeholder involvement until the end of the project. | Frequent stakeholder engagement through iterative reviews and feedback. | Close collaboration with customers and stakeholders throughout the project. |
| Delivery Time | Final product is delivered after all phases are complete, resulting in a longer delivery time. | Deliveries are incremental, allowing users to benefit from partial functionality early in the project. | Regular deliveries of functional software, providing value to users throughout the project. |
| Quality Assurance | Rigorous testing is performed after development, potentially leading to lower quality if issues are discovered late. | Frequent testing and refinement lead to potentially higher software quality. | Continuous testing and integration practices enhance software quality. |
| Adaptability | Best for projects with well-defined and stable requirements. | Well-suited for projects with evolving or unclear requirements. | Highly adaptable and suitable for projects with changing requirements. |
