EMEP Technical Requirements: Functional and Non-Functional - EMEP

EMEP technical requirements define measurable behaviors for all 16 internal abstractions. Requirements are grouped into eight categories. Each row includes a verification method. This page also provides a mindmap of requirement categories.
