The 6 Phases of the Software Development Life Cycle (SDLC)

The software development life cycle (SDLC) is a process that outlines the stages involved in developing software from conception to delivery.

The six phases of the SDLC are:


·       Deployment:

Deployment is the process of delivering software or an application from the development environment to the production environment. It involves installing the software on the production servers and making it available to the end users. The deployment phase is a critical part of the software development life cycle as it determines the success of the software application.

·       Planning:

Planning is the first phase of the software development life cycle (SDLC) that involves defining the scope of the project, identifying the objectives, and developing a plan to achieve them. The planning phase is crucial as it sets the foundation for the entire software development process.

·       Defining

Defining is the second phase of the software development life cycle (SDLC) which involves gathering and analyzing the requirements in detail to define the scope of the project. This phase is critical as it ensures that the development team understands the customer's needs and expectations and creates a plan to meet those requirements.

·       Designing

Designing is the third phase of the software development life cycle (SDLC) that involves creating a detailed plan for the software system based on the requirements gathered in the defining phase. The design phase is critical as it sets the foundation for the implementation phase and ensures that the final product meets the customer's needs and expectations.

·       Building

The building is the fourth phase of the software development life cycle (SDLC) that involves the actual development of the software system based on the design specifications created in the previous phases. The building phase is critical as it is where the software product is created and tested to ensure that it meets the requirements defined in the earlier phases.

·       Testing

Testing is the fifth phase of the software development life cycle (SDLC) that involves verifying and validating the software system to ensure that it meets the requirements defined in the earlier phases. The testing phase is critical as it ensures that the software product is free from errors, bugs, and defects before it is released to end-users.
