Design and strategy for IT Governance had been performed, and a complete assessment of 35 COBIT 2019 Core Process was performed, and which led to an implementation improvement road map. A complete design of MCIT Governance System framework and methods wad done, and all IT Governance Department services, processes, organization, Measures, standards, and culture had been detailed and documented. We used our Tamayyoz Gateway to capture knowledge about all of the Governance Framework Components.
