Agile Development
What Is Agile Development?
Agile Development is a flexible approach to project management and software development.
It is all about:
- Deliver value in small, manageable steps,
- Work collaboratively, and
- Adapt quickly to changes.
Agile encourages teams to be responsive and meet evolving customer needs instead of sticking to a rigid plan.
How Did Agile Development Begin?
The roots of Agile go back to 2001 when 17 software developers came together to write the Agile Manifesto. This document laid out four key values and 12 principles designed to make software development more efficient and customer-focused.
What Are the Core Values of Agile Development?
| Core Value | Focus |
|---|---|
| Individuals and interactions | Over processes and tools |
| Working software | Over exhaustive documentation |
| Customer collaboration | Over contract negotiation |
| Responding to change | Over following a fixed plan |
What Makes Agile Unique?
- Sprints: Short, focused work cycles (often 1–2 weeks).
- User Stories: Features described from the user perspective.
- Continuous Feedback: Regular reviews ensure alignment with goals.
Example Workflow:
- Plan a sprint.
- Develop and test features.
- Review progress and gather feedback.
- Adjust and repeat!
