Interesting point, but an analogic argument can be applied to all those
who apply rigid standards where they are not necessary. If a product,
process or whatever does what it should do in an acceptable manner with
appropriate aids provided by the employer, then that is good enough. I
firmly believe that our industry is plagued by over-specification-itis.
This is often engendered by ignorance; a responsible person has no idea
what the ramifications of a process or product are so, instead of
learning what it does, he covers his ignorance by applying
specifications and standards, often irrelevant or far too severe, and
costing his employers an arm and a leg in consequence. I see many, many
examples of this in this forum, as well as visiting clients. In one
company which consulted me, the product was a range of cards for use in
ordinary PCs used in an office environment. I saved them ~40% of their
production costs and thereby increased their overall gross profitability
by ~10% simply by showing them that they did not have to build their
products to ultra-reliable military standards -- but it was a hard
battle convincing them.
I suggest that every manufacturing entity should carefully examine their
products and processes for over-specification-itis.
Sorry to diverge off-topic.
