I like "architecture is an aspect of design that can be used in more than one application." Here are some Definitions of Architecture with links to even better ones.

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

And I like http://www.martinfowler.com/ieeeSoftware/whoNeedsArchitect.pdf

The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus

Here is my 2c:
System architecture transforms requirements into components.
System design transforms components into classes.

How does that fit into the usage of the terms as a result instead of an activity? ("Let's discuss the systems architecture." or "The system has a brittle design.")

Hi Ilja,
Here is my interpretation of the usage of the terms:
"Let's discuss the systems architecture." - you are discussing about the set of components involved in the system, their dependencies and their deployment issues.
"The system has a brittle design." - the implementing classes are poorly designed (disregarding patterns and other oo principles).
Regards,
Nalla
