Resource Utilization
Resource utilization measures how efficiently a system uses computing resources such as CPU, memory, storage, network bandwidth, and other infrastructure during operation.
“The degree to which the amounts and types of resources used by a component or system, when performing its functions, meet requirements.”

Monitoring resource utilization helps identify performance bottlenecks and determine whether resources are used efficiently under different workloads.
Performance metric: Evaluates infrastructure usage.
Optimization: High utilization may indicate resource constraints.
Capacity planning: Helps estimate future infrastructure needs.
Real World Example
A regulated product team is preparing a release where Resource utilization appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Resource utilization as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Resource utilization and similar ideas.
The page becomes useful in practice because Resource utilization is connected to a specific testing decision, not memorized as a detached definition.
