Most of us live in a world surrounded by technology. It has been a major source of progress and comfort but… technology becomes obsolete rapidly. The newer the technology is, the more the obsolescence cycles are shortening. This is quite true for a smart phone or the latest TV sets, but can we consider that quick obsolescence is applicable for advanced industrial products like an aircraft, a rocket or even a nuclear plant? Well, these systems require much more time spent in design, development and field deployment… Even though the innovation efforts engaged are significant, they are rather slow compared to consumer devices or enterprise IT systems. Thus, obsolescence cycles are somewhat longer, but still a major source of risk for guaranteeing the proper operation of these industrial systems that need to last for decades and continue to operate safely.
