5. Important definitions
According to the definition of the CPS Framework:
A concern is an attribute of the CPS that a designer, manager, or operator is concerned about. Concerns are organized in a hierarchy.
Aspects are top-level concerns
Concerns are addressed by requirements, which are concise mandates that serve to assure the CPS against potential issues.
Only after all of the concerns under a given aspect have been addressed by requirements, can an aspect be considered addressed. When all aspects have been addressed can a CPS be considered assured.

6. Objective
Visualization and interactive dashboard that can reveal concerns, aspects, and requirements not being met in real time that can be understood at all levels of the CPS.
