Defining a Service in ITIL Terms

A service is a means of enabling value co-creation by facilitating outcomes customers want to achieve, without the customer having to manage specific costs and risks themselves — a genuinely precise definition, not just “something we sell.”

Value Co-Creation, Not Just Delivery

ITIL genuinely frames value as co-created between the provider and the customer, not simply delivered one-way — a customer’s own actions and context shape whether real value is actually achieved.

Outcomes vs. Outputs

An output is a tangible or intangible deliverable (a repaired computer); an outcome is the actual result the customer needed (being able to work again reliably) — a genuinely important distinction for understanding what service actually means.

Applying This to Everyday IT Support

Thinking in terms of genuine customer outcomes, not just completed tasks, shifts how a technician frames and prioritizes their own work.
