Signal guide
Know when a change is real, in plain words.
Fields
| Field well | What to put in it |
|---|---|
| Axis | A date or period, such as week or month. |
| Values | The measure, such as days from order to delivery or on-time orders. |
| Denominator | Optional: what the value is divided by, such as orders, for rates like errors per 1,000 orders. |
| Target | Optional: a target measure, drawn as a dotted line. |
| Phase (Pro) | A column that names each period, such as “Old picking route” and “New picking route”. The limits are recalculated where it changes. |
| Split by (Pro) | One row on the board per warehouse, ward or team. |
Set it up
- Add Signal to the report page (see Install the visuals) and drag in the fields above.
- In Format › Chart, set Better when to Higher, Lower or Neither, and list the measures where lower is better.
- Chart type is Auto: an XmR chart for a measure, a p′ chart for a share with a denominator and a u′ chart for a rate (Pro). You can pick a run chart (median, no limits) instead.
- With more than one measure, or a Split by field, Signal shows the board (Pro): one row each, with a mini chart of the last 26 points, the latest value, the verdict and the target.
In the report
- Hover a point for its value, the mean, the limits, the target and the signal it is part of.
- Click a point to filter the report to that period, or a board row to filter it to that item; the rest dims.
- Light or dark background, high-contrast mode, and your own colours.
- Tab into the chart and move between points with the arrow keys; screen readers hear each point’s date, value and signal.
- The format pane, the labels and the messages are in English and Norwegian.
Pro features
- Phases: limits recalculated after a change
- p′ and u′ charts for shares and rates, with Laney’s adjustment
- Board view: several measures, or one row per item, each with a mini chart, verdict and target
Pro features need a licence key for Signal or Everything, or a 14-day trial key. Without a valid key, Signal draws the first measure as one XmR chart with one set of limits, with a short notice above the chart and a “Try Pro free” button. Everything else keeps working. See Add your licence key.
