The Software development life cycle (SDLC) is a structured, step by step process used by software engineering teams to design, develop, test and deploy high quality software efficiently and cost effectively.
Key phases in SDLC:
Planning and Requirement Analysis: Gathering stakeholder needs, defining the scope, estimating costs, and assessing project feasibility.
Design: Creating the software architecture, data models, system interfaces, and technical specifications based on the requirements.
Development: Developers write the actual source code according to the design documents, breaking the workload into modules.
Testing: Quality Assurance (QA) teams test the software for bugs, security vulnerabilities, performance bottlenecks and compliance with original requirements.
Deployment: Releasing the software to a live production environment so end-users can access it.
Maintenance: Ongoing monitoring, patching bugs, applying security updates, and adding new features based on user feedback.
