Impact¶
Impact is the number shown in the first column of the anomalies page. It tells you two things at once: how far the month was from normal, and in which direction.
How it is calculated¶
For an anomalous month, FinSentry measures the gap between the actual value and the average of the six months before it:
If the anomaly covers several months in a row, the monthly gaps are added together.
The number keeps a sign: an unusually high month shows a positive impact, an unusually low month a negative one. It is shown in the metric's own unit (euros, percent, hours, and so on).
The unit in the column header¶
The header reads Impact (X), where X is the unit shared by most of the
anomalies in the list. Each anomaly still uses its own metric's unit in the
detail view.
Impact number vs. badge colour¶
The number and the coloured badge measure different things:
| Element | Tells you |
|---|---|
| Impact number | Size and direction of the move, in the metric's unit |
| Badge colour | How unusual the move is compared with the metric's normal swing |
A steady metric can show a small impact number with a strong colour, and a noisy metric can show a large impact number with a mild colour. Read both together.
Note
Impact is not converted to a common currency or a 0–100 score. Comparing impact across metrics with different units needs care.
Sorting¶
The anomalies page is sorted by impact by default, largest first.
