RReeccaapp ● Usingproduction environment is not recommended ● Very often development environment not reflects what are in productions ● Setting up an environment is pain in the butt ● Consistent environment is hard to archive across multiple sites, and developers ● Setting up an environment is boring ● An environment sometimes is unreproducible ● Setting up an environment is Full of tedious crap ● Testing on production is a bad practice ● Setting up an environment time consumer ● Testing on development environment does not guarantee that works the same on production ● Setting up a environment is very detail oriented ● An environment sometimes is unreproducible ● Developers setting up its own environment on his own way.. ● Setting up consistent environments is a nightmare ● Products have deadlines to accomplish ● Developers are tied to a deadline ● Time is what developers need the most
