It is absolutely true that there is always a scope to improve your software. Obviously, we are going to talk about ‘How to design a better software’ in this article. We will continuously be adding points to this article in future also if we feel that they are appropriate.

In this article, we will focus on each & every aspect that can help to have a good understanding for better software design.

Please share them with others as well.
