Subject: FW: [plcs-dex] Classification of type and individual
I have
grave reservations about using the term "typical". I will leave to my office
colleagues to debate the finer point of change control but I fear the impression
of imprecision that the word creates.
In
PLCS we have always had to grapple with the bridge from the design
environment to the real world of supporting realised products. In the design
world, product definitions go through iterations as the design is improved to
eliminate failure modes, enhance functionality and simplify manufacture. As
digital data, each iteration can be identified as a new version
through the application of a rigorous change control mechanism.
At
some point we actually get round to building a few. Once built, each
product takes on a life of its own, able to be referenced back to a
design version only if you are lucky ( :-( but remember I am a real world
support engineer by trade so forgive the doubt!)
PLCS
must cope with the fact that the as-built version of a realised
product behaves differently from a design version. Realised products can always
be defined, not necessarily by reference to an identifiable
design version but always by identification of actual parts
fitted (because you can go and have a look). The differences from the design may
or may not be covered by authorised variances (concessions).
I
cannot see what value a "typical" option is adding.
