The universal design pattern has a slightly different goal.

In theory, using the universal design pattern should GUARANTEE that a
software design has a (reasonably) high level of quality across all
quality factors.
Much like applying a residential construction code guarantees that a
house is safe.

Of course, that does not guarantee that a quality (say performance) is
in fact high enough for a specific purpose.
Neither does the universal design pattern guarantee that a software
system meets any other specific requirements.

However - and this is what I was referring to in the initial quotation
above - the universal design pattern makes software designs highly
transparent.
Transparency is after all a quality.
And therefore, I believe the universal design pattern generally does
support analysis of quality factors.
