What is SDLC in Software Engineering

Software Development Life Cycle (SDLC) is a systematic approach to building software applications, ensuring they meet quality standards, user requirements, and business goals. It defines a step-by-step process that development teams follow to create, test, deploy, and maintain software efficiently.

Key Phases of SDLC

• Planning: Defines project goals, feasibility, budget, and timelines. Helps in risk assessment and resource allocation.
• Requirement Analysis: Developers and stakeholders gather functional and non-functional requirements. Clear documentation is created to avoid misunderstandings.
• Design: Involves creating software architecture, data models, and system designs. Acts as a blueprint for developers.
• Development: The actual coding phase where developers write, compile, and integrate code based on design documents.
• Testing: Quality assurance teams conduct unit testing, integration testing, and user acceptance testing to identify and fix issues.
• Deployment: Once tested, the software is deployed in a live environment where users can access it.
• Maintenance & Updates: Regular updates, bug fixes, and improvements are made to keep the software functional and up-to-date.
