Designveloper 153

SDLC provides a systematic approach to building software towards successful product deliverables within the timelines, whereas Agile has a faster development approach and speeds up the development process in an effective and efficient manner.


Agile is a well-known development methodology and the best approach for many development teams, especially those looking to create a continuous delivery environment. Agile software development life cycle is a mindset from the Agile Manifesto which came out in 2001 containing 12 principles and 4 values written by 17 software developers.

Mainly it is an approach towards the software development life cycle process. It focuses around iterative development, short cycles, getting feedback and adapting to the new requirements. Solutions develop through interactions between self-organizing cross-functional teams.

Benefits of Agile:
