Why Agile methodology basics in Intro to Computing? - Purpose & Use Cases

The Big Idea

What if you could catch mistakes early and change plans easily while building something important?

The Scenario

Imagine a team building a big puzzle together, but they only see the picture on the box after finishing all the pieces. If the picture changes halfway, they have to redo many pieces.

The Problem

Working step-by-step without checking often means mistakes pile up unnoticed. Fixing them later wastes time and energy, and the final result might not match what people really want.

The Solution

Agile breaks work into small parts and checks progress often. This way, the team can quickly fix mistakes and change direction if needed, making sure the final product fits what users want.

Before vs After

✗ Before

Plan whole project -> Build all features -> Test at end -> Deliver

✓ After

Plan small part -> Build -> Test -> Get feedback -> Repeat

What It Enables

Agile lets teams deliver better results faster by adapting to change and learning as they go.

Real Life Example

A software team releases a simple app version quickly, then improves it step-by-step based on user feedback, avoiding wasted effort on unwanted features.

Key Takeaways

Manual, big-step work risks late surprises and wasted effort.

Agile uses small steps with frequent checks to stay on track.

This approach helps teams adapt and deliver what users really need.
