Jean-Baptiste: At a higher level, at governance level, in order to drive the technological risk down to an acceptable level throughout the development program, a test incremental strategy is defined early on. And this test strategy will be composed of a set of test campaigns covering product requirements in a comprehensive manner – of course, focusing on the new technologies that have not been embarked already in similar products. And physical test campaigns require a large amount of time and money and often sit on the program critical path. So, it's really important to take care of these aspects because they have an impact at program level.
Along with the test plans that are part of this incremental test strategy, the associated test means – that will implement, enable us to execute this test – are also specified early on and they will have to be developed as well. So for example, companies have to test specific architectures or maybe they have already have that in their test center, or maybe they have to procure some test center facility. But all the equipment, it's in the end not so far from manufacturing, when you design the manufacturing system.
