The comparison between quality and safety PD also indicated
that the companies were not aware of their similarities and, as
a result, they were not taking advantage of the synergistic relationships.
In company A, it was clear that quality and safety PD
were managed by completely different mechanisms and staff. In
this company, no reasonable justification was identified for not
extending some practices used by quality PD to the safety ones.
As another example of the impact of this fragmented management
structure, PQ2 displayed H&S hazards, a problem originated from
the lack of a design team involving both H&S and quality control
staff.
