A turnkey solution is a total solution which allows the user to “turn a key and the system is ready to go”. Originating in the IT sector, turnkey systems include all necessary hardware and software. They are typically developed by original equipment manufacturers (OEM).
Germans prefer turnkey systems, as the receiver of the system, whether they are in the buiness-to-consumer or business-to-business context. Conversely, Germans prefer to develop and market turnkey systems. In fact, many German manufacturers will go as far as to make their own tools and machines, in order to make the products they then sell.
