In ITIL 4, right at the heart of the guidance, is this core idea that if we're gonna be a successful service provider, we really need a system by which we're gonna be able to deliver the correct products and services for the organization. And we call that system the ITIL Service Value System. Within the ITIL SVS, as it's truncated to, we take the idea that we understand the consumers and their demand and their, often the opportunities where they need new products and services and in a systemic way, we, as a successful service provider, be able to translate that into a set of products and services that ultimately do realize the value that the end business users and consumers require. What makes up that system though, is actually five elements which cover several things. Not just the practices that we need to be able to demonstrate as a service provision organization, but the principles by which we're gonna go and do fantastic service and products. The governance by which we're gonna direct and control the organization. The need to improve and continually improve the nature of the products and services. And right in the middle of the Service Value System, this idea of a Service Value Chain by which we'll run a set of integrated but often co-dependent, sort of, activities by which we'll actually deliver the products and services successfully to the end consumers. But in summary, the SVS is the way that we're also gonna co-create value to the end consumers.
