# How To Review (Re)Forecast Accuracy

## Objective

Review how completed reforecasts performed against demand that had already arrived.

## Environment

- Your reporting access includes the **Forecasting** tab.
- Reforecast runs completed during the period you want to review.

## Resolution

1. Open **Reporting** and select **Forecasting** under **Planning**.
2. Set the completion-date range and any queue filter. The queue filter selects runs that covered a selected queue; each displayed score still covers the run’s full queue scope.
3. Read **Average reforecast accuracy** as the mean of stored scores from completed runs. Each run counts once, regardless of its volume.
4. Review **Reforecast accuracy per completed run** and the run table to locate changes. Check **Queue scope**, intervals evaluated, actual volume, and change versus the previous scored run.
5. Use **Initial forecast accuracy** only as context. It averages selected-model backtest scores for distinct parent forecasts and uses a different evaluation window.
6. Open a run for more detail if an outlier needs investigation. Its current comparison can differ slightly from the stored score because more actuals may have arrived since the run completed.

**N/A** means a run had no stored accuracy score and is excluded from the average and chart. A score of **0%** means the evaluated miss exceeded the actual volume; it is a measured result.

### Note: Different evaluation windows

After step 5 in resolution. Initial forecast accuracy is a historical model backtest; reforecast accuracy measures elapsed intervals at run completion.
