Software Development Life Cycle (SDLC)
A structured framework that defines the phases and processes involved in developing software applications from initial conception to deployment and maintenance. The SDLC provides a systematic approach to software development that ensures quality, efficiency, and successful project completion through well-defined stages and deliverables.
SDLC Phases
The traditional SDLC consists of several key phases: requirements gathering and analysis, system design, implementation (coding), testing, deployment, and maintenance. Each phase has specific objectives, deliverables, and quality gates that must be completed before proceeding to the next stage, ensuring thorough planning and execution.
SDLC Methodologies
Various SDLC methodologies exist to suit different project needs, including Waterfall for sequential development, Agile for iterative development, DevOps for continuous integration and deployment, and Spiral for risk-driven development. Modern organizations often adopt hybrid approaches that combine elements from multiple methodologies to optimize their development processes.
