Why Agile manifesto and principles in Software Engineering? - Purpose & Use Cases

The Big Idea

What if your team could build software that changes with your users' needs, not against them?

The Scenario

Imagine a team building software by planning every detail upfront and sticking strictly to that plan for months.

When users want changes or new ideas come up, the team struggles to adapt quickly.

The Problem

This rigid way is slow and frustrating.

It causes delays, misunderstandings, and unhappy customers because the team can't easily change course.

The Solution

The Agile manifesto and principles encourage teams to work in small steps, talk often, and welcome change.

This makes software development faster, flexible, and more focused on what users really need.

Before vs After

✗ Before

Plan everything upfront; follow plan strictly; deliver at end.

✓ After

Work in short cycles; get feedback; adapt and improve continuously.

What It Enables

Teams can deliver better software faster and respond smoothly to change.

Real Life Example

A team releases a simple app version quickly, then improves it step-by-step based on user feedback, instead of waiting months to launch a full product.

Key Takeaways

Traditional methods are slow and inflexible.

Agile values collaboration, flexibility, and continuous improvement.

Following Agile principles helps teams deliver value faster and adapt to change.
