Mechanisms are provided, in a hierarchical feedback aggregation (HFA) system implemented in one or more data processing systems, for collecting and presenting user feedback information for a composite offering. A backend engine of the HFA system, implemented in a first data processing system, registers a hierarchical feedback model for the composite offering. A frontend engine of the HFA system, implemented in a second data processing system, receives user feedback for an identified component of the composite offering. The backend engine of the HFA system generates an aggregate user feedback score for the identified component based on a combination of the user feedback for the identified component and aggregate user feedback scores for child components of the identified component in the hierarchical feedback model. The backend engine outputs a representation of the generated aggregate user feedback score for the component to a user.
