Techopedia Explains Production Environment
One way to define a production environment is by contrasting it with a testing or development environment. In a testing environment, a product is still being used theoretically. Users (typically engineers) look for bugs or design flaws. In the production environment, the product has been delivered and needs to work flawlessly.
