Period Comparison
Compares one period's data against the previous one, analyzing changes and anomalies. Use to understand what changed.
Pack: Reports & DecisionsProcedure
- 1Define the two periods, same length
- 2Compare metrics and compute absolute and percentage change
- 3Flag anomalies: changes beyond the datum's typical threshold
- 4For each anomaly, list 3 verifiable hypotheses (not one explanation)
- 5State which data would be needed to confirm
Rules
- · More revenue never equals success alone: look at margin with revenue
- · Anomalies are flagged, never explained with certainty
- · Every change comes with its absolute-value change
Expected output
Comparison table (period A, period B, delta, delta %) + anomalies + verifiable hypotheses
When not to use it
- · Different-length periods: normalize per day before comparing
- · Data with fewer than 2 periods: comparison is meaningless
