Notes on Software Product Lines

I wandered into the concept of "Software Product Lines" and am deeply intrigued.

It seems to be an evolutionary step beyond SOA or SOOS, to a means of developing software solutions with change, flexibility (aka versions) built into the design - treating the assets of a product from models, requirements, and other artifacts through to components in a designed (read: architected) manner to maximize the proverbial goal of reuse.
