FMEA and consideration of real work situations for safer design of production systems

Production equipment designers must ensure the health and safety of future users; in this regard, they augment requirements
for standardizing and controlling operator work. This contrasts with the ergonomic view of the activity, which recommends
leaving operators leeway (margins for manoeuvre) in performing their task, while safeguarding their health. Following
a brief analysis of design practices in the car industry, we detail how the Failure Modes and Effects Analysis (FMEA)
approach is implemented in this sector.We then suggest an adaptation that enables designers to consider real work situations.
This new protocol, namely, work situation FMEA, allows experience feedback to be used to defend the health standpoint
during designer project reviews, which usually only address quality and performance issues. We subsequently illustrate the
advantage of this approach using two examples of work situations at car parts manufacturers: the first from the literature and
the second from an in-company industrial project.
