Episode 11: What is a Service?

At the heart of ITIL lies one fundamental question: what is a service? In this episode, we’ll unpack the ITIL definition of a service as a means of enabling value co-creation by facilitating outcomes that customers want to achieve, without the customer having to manage specific costs and risks. Two key ideas drive this definition: utility and warranty. Utility is about fitness for purpose — does the service do what it’s supposed to do? Warranty is about fitness for use — does it deliver reliably, at the right level of performance and availability? These two pillars combine to create real value for the customer.

Through relatable examples, such as using an online banking app or streaming your favorite show, you’ll see how utility and warranty play out in practice. Without utility, the service is meaningless; without warranty, it’s unreliable. Together, they form the backbone of how ITIL defines and evaluates service delivery. By mastering this concept, you’ll gain clarity not only for the exam but also for real-world decision-making about service design and delivery. This episode was produced by BareMetalCyber.com.
