The attributes encompassed by the framework proposed by this
article are applicable both to PD designed for quality control and
to those designed to control hazards to health and safety at work
(H&S). This integrative perspective between quality and H&S might
be considered as a distinctive feature of the proposed framework, as
both companies and the academic literature usually deal with each
type of PD separately. According to Stewart and Grout [6], this is
due to the fact that, typically, researchers and practitioners devoted
to quality control have little technical knowledge of H&S, and vice
versa. The application of the framework is exemplified by means
of applying it so as to analyze four PD: two of which are concerned
with quality and the other two with safety.
