5. Assessing and preventing risks

In order to detect, as early as possible, the prevention plans that need to be put in place in manufacturing, it is advisable to establish a principle of risk detection, their relative severity, their possible frequency and their ease of detection. These prevention plans are commonly referred to as FMAE (Failure Mode and Effects) or AMDEC (Analysis of Failure Modes, Effects and Criticality).

In this type of approach, three criteria are evaluated:

• the criticality of the failure, i.e. the importance of the impact caused by this failure;

• the difficulty of detecting this failure;

• the probability of such a failure occurring.

The "traditional" use of these indices considered that the order in which failures were ranked...
