The design concern refers to a specific aspect or consideration that needs attention during the design process of this particular product.
The assessment measures are what will be measured to determine how the design performs with respect to the design concern.
If the design concern is a requirement, the requirement lists the value of the assessment measure that has to be achieved in order to comply with the requirement.
If the design concern is a goal, there is no requirement value. The goal describes the desired direction of the assessment measure in order to come closer to achieving the goal.
