Which description matches the CUSTOMER role in a service relationship?

ITIL 4 Foundation, objective 1. Key concepts of service management medium

Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.

Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.

How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.

The options

Not correct Uses the service day to day and raises requests when something goes wrong

Wrong. That is the user. Users consume the service in practice but are not accountable for the outcomes it is meant to enable.

Correct Defines the requirements for a service and takes responsibility for the outcomes of service consumption

Correct. Requirements plus ownership of the outcomes is exactly what distinguishes the customer from the other two consumer roles.

Not correct Authorizes the funding that pays for service consumption

Wrong. That is the sponsor. Money authorization is a distinct role from requirements and outcome ownership.

Not correct Supplies the resources and performs the service actions that deliver the service

Wrong. That is the service provider side of the relationship, not a consumer role at all.

Why

ITIL deliberately separates customer, user and sponsor because in practice they are frequently different people with different interests. Confusing them leads to designing a service for whoever pays or whoever complains, rather than for the party accountable for the outcomes.
