SDLC

The Software Development Life Cycle (SDLC) is a structured process used to design, develop, test, and deploy software applications. It provides a systematic framework for building software that meets user requirements, maintains quality, and stays within budget and time constraints. SDLC ensures that projects follow clear phases, from initial planning to maintenance, creating a predictable and repeatable process.
Common phases of the SDLC include planning, requirements gathering, design, development, testing, deployment, and maintenance. By following these stages, teams reduce risks, improve collaboration, and deliver software that aligns with business goals.
Advanced
SDLC methodologies vary, including Waterfall, Agile, Spiral, V-Model, and Iterative approaches. Each method adapts the core SDLC phases to suit project needs. For example, Waterfall follows a linear process, while Agile delivers software in short, iterative cycles.
Advanced SDLC practices integrate DevOps, continuous integration (CI), and continuous deployment (CD) to accelerate delivery and improve quality. Security is also embedded into the SDLC through DevSecOps, ensuring vulnerabilities are addressed early. Documentation, version control, and automated testing further strengthen the efficiency and reliability of the process.

Example
A retail company implemented Agile SDLC to modernize its e-commerce platform. By working in short sprints and involving stakeholders in reviews, the company reduced release times, increased feature adoption, and improved customer satisfaction compared to its previous Waterfall approach.
