The more automated the decision, the more dangerous invisible data becomes.
- Sensors and logs feel objective — but collection is selective.
- Dashboards compress reality into a few numbers and colors.
- ML pipelines inherit every upstream omission and unit mismatch.
- Automation turns local errors into organizational policy.

05 / 36
- Carefully selected sources: Where did it come from? Why trust the producer, device, process, or witness?
- Intentional transformation: Was it cleaned, joined, labeled, or summarized for the purpose at hand?
- Consumer fit: Is it delivered in the right format, freshness, and context for the audience?
It is data we can rely on because we understand its source, transformation, and use.

Trusted data comes from selected sources, is transformed for intended use, and delivered appropriately.

Design systems that demand trust, not blind belief.
