SDLC Models

Software Development Life Cycle (SDLC) models are structured plans that guide the creation of software, ensuring it meets quality and timeline goals. They outline stages like planning, designing, coding, testing, and deployment. Different models, such as Waterfall, Agile, or Spiral, organize these stages uniquely—some are sequential, like Waterfall, progressing step-by-step, while others, like Agile, allow for iterative development and frequent updates. These models help teams work efficiently, manage risks, and adapt to changing requirements, ultimately delivering reliable software tailored to user needs.
