What it is
Often included in PRDs but can be their own artifact for platform work. Make non-negotiables explicit so they don't get traded away mid-sprint.
Concrete example
“Job list must load in under 2 seconds for users with up to 1,000 jobs; comply with SOC 2 logging requirements.”
When to use it
Platform work, performance-sensitive features, regulated industries, and any feature where reliability is a buying criterion.
