A solution is defined as a product, service, or system delivered to the customer in SAFe. A solution can be a small mobile application built by a single Agile Release Train (ART) or a large automotive system of systems built by a network of Development Value Streams (DVSs) in a supply chain1. A solution may also be an insurance or banking product offered by a financial institution. Solutions can be the products a company sells or the internal products they use to run the business. They may provide direct value to an end-user or may be a component of a larger solution1.
