Software Development Lifecycle (SDLC): End-to-End Overview

A complete SDLC is composed of sequential or iterative phases that ensure software quality and project success.

SDLC Phases:

1: Requirement Gathering & Analysis – Understand what users need

2: Feasibility Study & Planning – Estimate cost, effort, and risks

3: System Design – Plan architecture, database, and interface

4: Development / Implementation – Write code and integrate modules

5: Testing & Quality Assurance – Validate functionality, performance, and reliability

6: Deployment & Release – Move software to production

7: Maintenance & Support – Fix issues and improve performance post-launch

key takeaway:

All SDLC phases work together to deliver high-quality software efficiently.
