VF — Cannot aggregate Value Proposition Components

AggregatedFrom / AggregatedTo is related to ValueAdd. This prohibits aggregation of ValuePropositionComponents.

Move aggregatedFrom / aggregatedTo association from ValueAdd to ValueElement

Move aggregatedFrom / aggregatedTo association from ValueAdd to ValueElement, so that value aggregation applies to both ValueAdds and ValuePropositionComponents, in any combination). The articulatedValue association becomes then redundant and can be removed. This more flexible aggregation of value also makes ValueImpactForProvider of ValuePropositionComponent redundant, so that it can be removed also. Value aggregation to a ValueProposition to the provider (the business) can be used instead.
