App Types, Verticals, and Scenarios
I think application types, verticals, and scenarios are a helpful backdrop for product-line engineering. You can use it to organize policies and requirements. It’s a way to increase precision.

How you implement security, performance, and other quality attributes has a lot to do with the application type and the scenario or context you are in.
