Surely software development is far-far from being science. Till this day it is more an art, unfortunately. Value/advantage of most concepts (TDD, Clean Architecture, SOLID, OOP etc) is not substantiated by any scientific research. For a scientist, the never-ending discussions about these concepts should stop after a single scientific paper, stating that "such a such groups of developers were given a task ... under such and such criteria, and it was found that those who followed concept X produced 20% more value for the same time and 67% of them said that they also felt more satisfaction as compared to those who didn't follow it." But there are practically no such papers. (I remember only one scientific paper on comparison Scala-vs-Java development speed, but it remains unknown for 99% of Scala and Java devs.)
I'm a small business programmer. I love solving tough problems with Python and PHP. If you like what you're seeing, you should probably follow me here on dev.to and then checkout my blog.

I agree. We could benefit from more scientific research about what works and what doesn't in software development. Thanks for your comment.
If your are interested by DevOps good practices back by science, read this excellent Accelerate book
You won't find SOLID, or OOP in there, but automated tests (and TDD), and Architecture.
