What is the ITIL Value System ?

The correct answer is C. ITIL Version 5 defines the ITIL Value System, or ITIL VS, as a model representing how all the components and activities of an organization work together to facilitate value creation through digital products and services. The ITIL VS combines governance and management of digital technology into one overall system. It shows how opportunity and demand enter the system and how the system produces value for the organization, customers, and other stakeholders. It includes five components: guiding principles, governance, value chain, practices, and continual improvement. Option A is incorrect because it defines a management practice, not the ITIL Value System. Option B describes governance of digital technology, which is only one component of the ITIL VS. Option D defines a value chain, which is also part of the ITIL VS but not the whole system. The ITIL VS is broader because it explains how governance, management, practices, continual improvement, and value chain activities work together.
