Example Requirements
Measurable targets you can lift into a real specification: scenarios with context, triggers, and acceptance criteria, sorted by dimension.
Within the Software Engineering literature you might find the term “quality scenario” for such examples. That term was coined by authors from the Software Engineering Institute (SEI), especially Len Bass et al. Read more on the background of requirements in our short article.
