A staging environment is a replica of the production environment that is used for testing and demonstrating the final product before deployment. A staging environment can help the web consultancy group avoid the issues reported by the customers, such as mismatched expectations and unexpected behavior, by ensuring that the product is shown in a realistic and consistent setting. A staging environment can also help the group catch and fix any bugs or errors before they affect the live site.
