In the three companies, the assessment of attributes was carried
out jointly by two members of the research team, one of whom had
a formal degree in industrial engineering and training in LP systems,
while the other, in addition to these, also had formal training in H&S
and ergonomics – this was the leading auditor. Thus, as occurred
in this study, it is recommended that the audit team have formal
educational qualifications in the areas mentioned, whatever the
type of poka-yoke assessed, be it quality or safety.
