# How To Compare A Reforecast With The Baseline

## Objective

See how newly forecast demand differs from the original forecast for the same dates and workstreams.

## Environment

- You have access to a generated forecast with a completed baseline and a completed reforecast run.
- You know which date range, queue, and channel you want to compare.

## Resolution

1. Open the forecast and select the **Forecast** tab. In **Inbound Volumes**, use the same dates and queue scope for the original forecast and the reforecast overlay. Read the chart labels to distinguish forecast, actual, and reforecast values.
2. Select **Reforecast** and open the completed run. Check its **Run time**, training window, and reforecast window so you compare the intended run and period.
3. In **Incoming Comparison**, select a **Queue scope** and **Channel scope** if the run includes several workstreams. Read the reforecast total, observed incoming volume, and accuracy.
4. Compare the direction and size of the change for the same scope. Review **Required Coverage Preview** separately if coverage has been calculated for the run; demand and coverage are different measures.

### Note: Accuracy needs actual data

After step 3 in resolution. Accuracy is unavailable for future intervals until those intervals have elapsed and actual data exists.
