Agile Methodology

Now a days every MNC in IT sector is following Agile methodology because of its advantage.
In the agile methodology, the team will design and implements the code for certain part of the Software according to client requirements and delivers the build to the testing team and client for the evaluation.

If the client and Testing team feedback is positive on the basis of requirements documents, then the development team moves to Remaining part of the software development ,

If they receives negative feedback the re-work will be done on the Developed software.

This is called one of the "test driven software development model" because the client will be closely associated with the development team and testing team. So there is a high chance to deliver the high quality product.  

The software engineers follow different approaches in development and testing. Agile methodology in testing is completely different from Other models .

In agile methodlogy the software engineers follow different frameworks to develop and to deliver the project.
The popular framework among all is "Scrum".

Tomorrow we will be discussing the complete scrum process in detail.
