SDLC

What is SDLC:

SDLC stands for 'Software Development Life Cycle'.It is the process of software development.It gives the protocol for software companies.The software development lifecycle is a structured process used to Requirements gathering, Planning, Design, Development, Testing, Deployment and Maintenance.

1.Requirements gathering:

In this stage our marketing team collects the data from clients with BRS(Business Requirement Specification) Document.Key roles business analyst and owners.

4.Development:

In this stage Developers build the software based on the approved design.We used in this step architect. Activities are in this step Coding,Code reviews, Unit testing and Version control management.

5.Testing:

Testing ensures the software meets requirements and is free from defects before release.We testing the code during developer in the process. That method is called Test Driven Development.(TDD)

Types of Testing:

Unit Testing-Verifies individual components.

System Testing -Validates the complete system.

Automation Testing - It helps teams test applications faster, more accurately, and supports continuous integration and delivery.

Finally we get the app from deployment and we check it any debugs and version of application.Activities: Bug fixes, performance tuning, updates, feature enhancements
Output: Patches, updates, new versions.
