Today’s topic is Software Development Life Cycle (SDLC) — the structured process used by companies to build reliable, scalable, and maintainable software.

If you’ve ever wondered:

How an idea becomes real software

Why projects fail or succeed

How teams plan, build, test, and deploy apps

This video explains SDLC step-by-step in simple language, without theory overload.

🔁 What Is SDLC? (Simple Definition)

The Software Development Life Cycle (SDLC) is a systematic process used to design, develop, test, deploy, and maintain software.

Think of SDLC as:

A roadmap for building software the right way.

🧭 The 7 Phases of SDLC (Explained Clearly)
1️⃣ Requirement Analysis

Understand what needs to be built

Gather business & user requirements

Define scope

📌 Mistakes here = project failure later

2️⃣ Planning

Timeline & cost estimation

Technology selection

Resource allocation

3️⃣ Design

System architecture

Database design

UI/UX planning

🧠 Blueprint of the software

4️⃣ Development

Actual coding

Frontend + Backend implementation

Feature development

5️⃣ Testing

Find and fix bugs

Ensure performance & security

Validate requirements

Tools:

Unit testing

Integration testing

Automated testing

6️⃣ Deployment

Software released to users

Production setup

Cloud/servers configured

7️⃣ Maintenance

Bug fixes

Updates

Performance improvements

📌 Software never truly “ends”

🏗️ Popular SDLC Models

✔ Waterfall — Linear, rigid
✔ Agile — Iterative, flexible (most popular today)
✔ Scrum — Sprint-based Agile
✔ DevOps — Continuous delivery & automation

💡 Most modern teams use Agile + DevOps together.
