Dependability data are essential for all predictive and mainly quantitative studies. They are of two types: event-driven and reliability-driven.
Event data are obtained from statistical studies of accidents and full-scale experiments. They therefore concern the "macroscopic" aspect and provide estimates of the behavior of an entire system under certain circumstances (large number of indiscernible or non-quantifiable events). They are particularly useful for assessing risks (probability/severity of consequences) and therefore safety.
Reliability data, on the other hand, is obtained by testing basic system components under given conditions (discernible, quantifiable events). They are therefore "microscopic" and are essential for the predictive methods described in the
In large, high-performance companies, the use of CMMS (computer-aided maintenance management) software that includes modules for collecting feedback enables analysis of all the parameters associated with the circumstances in which failures occur, and the time spent on corrective or preventive maintenance.
Feedback data collection systems are used to assess the performance of operational systems using quantitative indicators such as MTTF (Mean Time To Failure), failure rates, repair times and uptime.

Standards and norms
When it comes to standardization in the field of Dependability, there are a considerable number of international, national and industry-specific bodies and institutions which issue their own standards. In this section, we will only mention the main standards used in all industrial sectors and in the contractual clauses of invitations to tender. However, to avoid any ambiguity about the term standard, the definition...
