Which ITIL concept includes governance, practices, and continual improvement?

The ITIL Service Value System (SVS) is the core architectural concept of the ITIL framework. It describes how all the components and activities of an organization work together as a unified system to enable value co-creation. The SVS explicitly consists of five foundational components: Guiding Principles, Governance, the Service Value Chain, Practices, and Continual Improvement. These elements interact to ensure that the organization's inputs (opportunity and demand) are effectively transformed into valuable outcomes. Because governance, practices, and continual improvement are direct, structural components of this overarching system, the ITIL Value System is the correct answer.

B. The 'deliver' and 'support' value chain activities: These are specific operational activities within the Service Value Chain, not the overarching system that encompasses governance, practices, and continual improvement.
C. The 'focus on value' ITIL Guiding Principle: This is merely one of the seven guiding principles. It is a behavioral guide, not the structural framework containing governance and practices.
D. The 'value streams and processes' dimension: This is one of the Four Dimensions of Service Management, focusing specifically on workflows and operating models, rather than the overarching governance and improvement system.
