This chapter presents a rapid human data engineering (HDE) approach based on human systems engineering (HSE) principles to build a trustworthy private blockchain for large complex enterprises such as governments’ defense departments and its application to operational risk management. The adoption of HSE to the new field of big data and the Fourth Industrial Revolution opens the exciting field of human data engineering (HDE), human data integration (HDI), and user data interaction design (UDID). In this chapter, we first present the approach to HDE based on HSE, we then propose a detailed process of integration of human-centered system design (for risk management systems) with HSE (building the trustworthy private blockchain), and, finally, we present HDI and UDID through establishing trust and security of the private blockchain. At the end of this chapter, we provide potential future work in the field of HSE, HDE, HDI, and UDID.
