Software Development Life Cycle Process | SDLC Model

What is SDLC Process?

SDLC stands for Software Development Life Cycle. It is a process used to develop software in a structured and organized manner. It is a framework that outlines the different stages of the software development process, from the initial planning phase to the final deployment and maintenance phase. 

There are several different SDLC models, each with its own unique set of steps and deliverables.

Different Models in SDLC:

The most commonly used SDLC models include:

Waterfall: This model follows a linear and sequential approach, with each phase of the software development process being completed before moving on to the next phase. 

The phases include Requirements, Design, Implementation, Verification, and Maintenance. Read More

Agile: This model is based on iterative and incremental development, where requirements and solutions evolve through the collaborative effort of self-organizing and cross-functional teams. 

The Agile process is typically divided into sprints, where a set of tasks and deliverables are completed in a short period of time. Read More

V-Model: This model is based on verifying and validating the software development process. It is a variation of the Waterfall model and is often used in the development of safety-critical systems. 

It is characterized by a clear and rigorous approach, with each phase of the development process being linked to a corresponding test phase. Read More

Spiral: This model is a combination of the Waterfall and Iterative models, where the software development process is divided into small increments. Each increment goes through phases, including Planning, Risk Analysis, Engineering, and Evaluation.

Scrum: This is an Agile model that follows an iterative, incremental approach to software development. It is a lightweight framework used to manage complex projects, and it emphasizes collaboration, flexibility, and rapid delivery of working software. Read More

Each model has its own advantages and disadvantages, and the choice of model depends on the project's specific requirements and constraints. A software development team must carefully evaluate the project's goals, constraints, and risks before deciding which SDLC model to use.
