PQ1 and PQ2 scored 1.0 (attribute BP3) because their design
process did not involve a team that held formal design meetings,
which was the minimum requirement to score 2.0.
However, the design was not fully conducted by a single person,
since the workers interviewed reported that they were informally
consulted during the design phase. For PS2, attribute BP3
was considered to be not applicable, since the design of the
poka-yoke was specified in great detail by H&S regulations,
leaving no room for changes.
