Reporting Rules and Minimum Sample Sizes

P&C · Survey process owners · Leaders Updated July 2026

Reporting rules protect confidentiality and reduce the risk of over-interpreting small groups.

Core rule

Results should only be displayed where the required response threshold is met. Where the threshold is not met, the result should be suppressed, grouped with a larger reporting unit or handled through a different listening method.

Why this matters

Risk Consequence
Identification risk Employees may believe their responses can be traced back to them.
Misinterpretation risk A very small number of responses can create a misleading result.
Trust risk If employees feel confidentiality was weakened, future participation will suffer.

Practical reporting choices

  • Group small teams into larger work areas.
  • Avoid combined filters that create very small groups.
  • Use qualitative follow-up carefully where survey data cannot be safely segmented.
  • Present trends and themes rather than individual comments where comments may identify people.

Workshop rule

If a result cannot be safely shown in a formal report, it should not be casually discussed in a workshop or leadership meeting.
