ITIL4F ITIL Service Value System Practice Question
A service provider guarantees 99.9% uptime for a critical application. This guarantee is an example of which component of service value?
⚠ Common exam trap
A common mix-up: candidates confuse 'utility' (what the service does) with 'warranty' (how well it is delivered), especially when a numeric guarantee like uptime is presented, leading them to incorrectly select utility because they associate performance metrics with functionality.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Warranty
The 99.9% uptime guarantee is a warranty because warranty ensures that a service will meet agreed-upon levels of availability, capacity, continuity, and security. In ITIL 4, warranty is the assurance that the service will perform as promised under defined conditions, directly addressing the 'fit for use' aspect of service value. This guarantee specifically quantifies availability, a core warranty dimension.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Output
Why it's wrong here
An output refers to a tangible or intangible deliverable produced by an activity within a service. While a service produces many outputs, such as processed data or reports, a 99.9% uptime guarantee is a characteristic of the service's performance and availability, not a direct deliverable itself. It describes a condition under which outputs are reliably produced, rather than being an output.
- ✗
Outcome
Why it's wrong here
An outcome represents the result achieved by a stakeholder when using a service, often enabled by one or more outputs. It signifies the value realized by the consumer, such as increased efficiency or reduced costs. A guarantee of 99.9% uptime, however, is a prerequisite condition that helps enable desired outcomes by ensuring service availability, rather than being the ultimate result or benefit itself.
- ✓
Warranty
Why this is correct
Warranty provides assurance that a service will meet agreed requirements and is 'fit for use,' addressing how the service performs. This includes aspects like availability, capacity, continuity, and security. A 99.9% uptime guarantee directly specifies a critical performance condition, confirming the service's reliability and ensuring it consistently meets its defined operational standards for the consumer.
- ✗
Utility
Why it's wrong here
Utility describes the functionality offered by a service to meet a particular need, answering the question 'what the service does.' It focuses on whether the service is 'fit for purpose' by providing the necessary features and functions, such as data processing or communication capabilities. Uptime, conversely, relates to the service's availability and performance, which is a 'how' aspect, distinct from its core functional capabilities.
