Which framework provides a comprehensive IT governance model emphasizing value delivery, risk optimization, resource management, and performance measurement?

• A. ITIL 4
• B. NIST SP 800-53
• C. ISO/IEC 38500
• D. COBIT 2019

Answer: (D)

Grasping IT governance means looking for a framework that ties IT decisions directly to business value while providing clear ways to manage risk, optimize resources, and track performance. COBIT 2019 fits this need as a comprehensive IT governance and management framework. It defines a complete set of governance and management objectives focused on delivering value from IT, optimizing risk, efficiently using resources, and measuring performance against goals. This structure helps an organization align IT with strategy, establish clear accountability, and drive continuous improvement through capped metrics and governance practices. While other frameworks have important roles—ITIL 4 emphasizes service management, NIST SP 800-53 concentrates on security controls, and ISO/IEC 38500 offers governance principles—the breadth and explicit emphasis on value delivery, risk optimization, resource management, and performance measurement make COBIT 2019 the best fit for a holistic IT governance model.
