The analysis focuses on the technical, organisational and legal areas of real laboratories. Insights gained, e.g. how a transfer from laboratory to field tests of systems, sensors and actuators can succeed, are placed in a comparable context in order to identify opportunities, gaps and trends for general recommendations for action. It is essential to define the concrete roles of the actors involved in the real laboratory and to successfully communicate the special opportunities for potential innovations through such tests under real conditions to the outside world.
