Abstract

This study investigates the solutions incorporated by the Architecture Board in global healthcare enterprise (GHE) to mitigate architecture risks especially in Digital IT areas covering Big Data while implementing the "Adaptive Integrated EA framework," which can be applied in companies promoting IT strategy with Cloud/Mobile IT. The study proposes and verifies the strategic risk mitigation model for digital transformation covering Big Data in Architecture Board, at the same time as this study revealed the distribution of solutions across the architecture domains in Enterprise Architecture covering applications and technologies with Cloud/Mobile IT/Big Data/Digital IT to mitigate risks. An in-depth analysis of this distribution resulted in the definition of the effective strategy elements to mitigate risks and a practical guidance for companies that consider Risk Management for Digital Transformation while starting up the Architecture Board in Enterprise Architecture with IT strategy covering Digital IT related elements focusing on Big Data.
