Global supply and value chains are extensively scattered with organizations located in different parts of the world. Usually, they have different processes in place, use different technologies and have different trustworthiness targets. So, it is not trivial to achieve an end-to-end trustworthiness along the entire supply chain in such a diverse setup. Based on our previous research on organizational and product trustworthiness, in this publication, we concentrate on researching aspects of trustworthiness of data in value networks that comprise several heterogeneous supply and value chains. In previous publications, we introduced the establishment of organization and product trustworthiness by exchanging trustworthiness expectations and capabilities. In this publication, we go a step deeper and examine the trustworthiness of data in value networks that comprise supply and value chains and the aspects of trustworthiness of data itself.
