Definition
A group intentionally not exposed to the campaign.
Compare customers receiving nurture against similar customers receiving nothing.
“When someone uses “Holdout group,” ask what rule, owner, or outcome they mean in this system.”
The fuller explanation
Understanding Holdout group
Holdout group is a practical concept in testing and release. Put simply, a group intentionally not exposed to the campaign. The useful boundary is what the term changes about a decision, owner, or system behavior.
In practice, teams should define the inputs, expected outcome, owner, and exceptions. A concrete example is: Compare customers receiving nurture against similar customers receiving nothing. The exact implementation will depend on the organization’s tools and operating model.
The term becomes operational only when people can observe it consistently and act on it. Document the definition, connect it to the relevant workflow or report, and revisit it when systems or responsibilities change.
Common mistakes
- Testing only the happy path.
- Releasing without recording the expected result and owner.
