2.1. Product and Service Management
💡 First Principle: This topic names the raw materials of the entire framework — what a product is, what a service is, and what "good" value looks like — because you cannot reason about creating value until you can name the things that carry it.
The stakes here are foundational: nearly every other definition in ITIL is built from these terms. Get the product-versus-service distinction wrong and the four dimensions, the lifecycle, and the value chain all blur together. The mental model that holds this topic together is a simple supply chain of value: an organization configures resources into products, offers services built on those products, and the consumer experiences value — gauged through utility, warranty, experience, and sustainability.
⚠️ Common Misconception: Many learners treat "product" and "service" as synonyms because everyday speech uses them interchangeably. In ITIL they are distinct: a product is built from resources, while a service is delivered to enable outcomes. The subsections below draw that line precisely.
