We present the development of a visualisation framework, used to provide formative feedback to clients who engage with data brokering companies. Data brokers receive, clean, store and re-sell data from many clients. However the usage of the data and the brokering process can be improved at source by enhancing the client’s data creation and management processes. We propose to achieve this through providing formative feedback, as a visualisation report, to the client. Working closely with a travel agent data broker, we present a three-part framework, where we (1) evaluate data creation and provision processes of the client, (2) develop metrics for quantitative analytics on the data, (3) aggregate the analytics in a visual report.
