Create a short evidence summary from three fictional records. This exercise teaches the product's evidence model without requiring an account, weather downloads, or a running app. The records are teaching examples, not observations from a real storm or payloads for a deployed API.
Use this fictional set:
| Record | Content |
|---|---|
| A | A radar-derived estimate belongs to event revision 1 |
| B | An external ground report arrives and is included in revision 2 |
| C | A sample property intersects the estimated event footprint in revision 2 |
-
Write a classification beside each record. Use the evidence labels. Keep the source observation separate from a conclusion derived from it.
-
Compare your answer with the expected interpretation.
Record Interpretation A radar-derived; the estimate is not a field inspectionB report-observed; a report does not confirm conditions at every nearby propertyC A modeled exposure relationship; it does not confirm physical damage -
Add an uncertainty statement to your summary. Use "confidence not supplied" for this exercise. Do not invent a numerical probability or promote a radar-derived record to field-confirmed because it appears convincing.
-
Record that an earlier decision used revision 1. Record the new report separately under revision 2; do not rewrite what was available earlier.
-
List the provenance you would need to verify the summary: source identity, observation and acquisition times, source version, event revision, and the derivation method. Mark values absent from the exercise as unknown.
-
Write the final summary. It should communicate the following result:
Revision 1 contained radar-derived evidence. Revision 2 added an external report. The sample property intersects estimated exposure in revision 2; physical damage remains unconfirmed. Source details and confidence were not supplied in this exercise.
You now have a summary that preserves evidence type, uncertainty, and changing knowledge. Compare it with Architecture concepts to understand how the same distinctions carry into action plans and outcomes.
