What are the 7 phases of SDLC?

Software Development Life Cycle (SDLC) is a process that software development teams use to design, develop, test, and deploy software applications. SDLC helps in providing a systematic approach to software development, ensuring that the software development process is completed efficiently and effectively. There are seven phases of the SDLC, which are as follows:


1:- Planning Phase: 

In the planning phase, project objectives and requirements are defined, and the feasibility of the project is assessed. The project plan is prepared in this phase, which includes the project scope, timeline, budget, and resources required for the project.


2:- Analysis Phase: 

In the analysis phase, the software requirements are gathered, analyzed, and documented. The purpose of this phase is to understand the needs of the end-users and to identify any potential problems that may arise.


3:- Design Phase: 

In the design phase, the software is designed, and the software architecture is created. This phase includes the design of the database, user interface, and software modules. The software design document is created, which includes the technical specifications of the software.


4:- Development Phase:

 In the development phase, the actual software development process takes place. The software development team creates the code for the software, which is then compiled and tested. This phase includes coding, testing, and debugging.


5:-Testing Phase:

 In the testing phase, the software is tested to ensure that it meets the user requirements and performs as expected. The testing can be done in various ways such as unit testing, integration testing, system testing, and acceptance testing.


6:- Deployment Phase:

 In the deployment phase, the software is deployed to the production environment. The deployment phase includes installation, configuration, and release of the software. The software is also made available to the end-users.


7:- Maintenance Phase: 

In the maintenance phase, the software is maintained and updated. This phase includes bug fixes, software updates, and enhancements. The maintenance phase ensures that the software remains operational and performs as expected.
