**Brownfield** refers to the implementation of new systems to resolve IT problem areas while accounting for established systems. New software architecture must account for existing and running software.

A commonly used IT term, Brownfield was borrowed from the building industry, where brownfield land describes a geographical location where new buildings may be constructed after considering the area's established structures and services.
