“A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it.” (Albert Einstein)
According to the ESA space standard ECSS-E-ST-10-02C, the goal of verification is to demonstrate, through a dedicated process, that the product meets the specified requirements. Verification in the field of mechanical engineering takes place at different levels of the product hierarchy, from the material level to the system level. Einstein was right when he pointed out that hypothesis and experiment are inextricably linked. In mechanical engineering, proof of concept is essentially based on two complementary verification methods: analysis and test.
Successful verification engineering is not only expressed by compliance with technical requirements. It is also capable of adhering to tight project constraints through a suitable combination of verification tasks at different product levels. Verification management controls the status of the component throughout its entire life cycle, from the design phase to end-of-life.
