RE: Principle of Least Power, "Motherhood and Apple Pie"

Yep.  Design principles inform designers.  They 
are not in and of themselves, designs or architectures.

I don't object to the principles.  It was the politics 
of the referenced article.  One doesn't need 70 gallons 
of mud to finish the wall.

BTW with respect to CTQ: the customer wants it all, 
now, and for nothing.  It takes testing to determine 
if the wall stands up to the kids, but anyone knows 
not to uncover the electrical outlets in the bedroom 
of two-year olds.  The customer may have to pay for 
features they don't know they need yet.  That is 
standardization at its best.  Worse isn't better here.

We could make these exchanges the work of this week. 
Again, my objection was to the politics of the article, 
not the principles.


From: Joe Gregorio []

Engineers, at least the good engineers, also understand CTQ. 

"CTQs (Critical to Quality) are the key measurable characteristics 
 of a product or process whose performance standards or 
 specification limits must be met in order to satisfy the customer. 
 They align improvement or design efforts with customer requirements."[1]


Over-engineering is just as much of a problem as under-engineering.

When I am putting up sheetrock, I don't measure it to the 32nd of an inch.
could, but it doesn't add to the quality, you're just going to tape
and mud those seams anyway.
