Heuristic

Choose a source that actually saw the work

More opinions do not automatically mean more information.

When it fits

Feedback is being collected because more raters feels more objective.

When to avoid it

Credible observers can still disagree; do not treat source selection as proof of truth.

Why it matters

For each question, prefer sources with direct exposure to the relevant behavior and enough context to judge it. A customer may know response clarity; a peer may know collaboration; a reviewer may know code quality. Do not ask every rater to judge every dimension.

An example

A stakeholder rates requirement clarity while a technical reviewer rates implementation maintainability; neither is asked to infer the other's domain.

Check your result

Each feedback source has a defensible observation window and question.

Keep this limit in mind

Credible observers can still disagree; do not treat source selection as proof of truth.

Evidence and sources

Supports

Feedback evidence suggests credible sources, facilitated interpretation and follow-up actions can influence whether multisource feedback is accepted and used.

These factors come largely from health-care and multisource-feedback research and need contextual adaptation.
