Accuracy tab

Use the Accuracy tab to view the historical net forecasts data in a tabular format. The Accuracy table is displayed with the forecast version and the forecast period. This data helps you to evaluate the reliability of the forecasts.

The Accuracy table is displayed only if you set the periodicity to one of these values:

  • Months
  • Weeks
  • CMonths

The types of Accuracy table:

  • Strategic accuracy: This table is displayed when the periodicity is set to Months or CMonths. The Strategic accuracy is calculated over 12 periods, which includes the current forecast period and 11 historical periods. The Rolling column displays the sum for each forecast version, which includes 12 forecast periods.
  • Tactical accuracy: This table is displayed when the periodicity is set to Weeks. The Tactical accuracy is calculated over 13 periods, which includes the current forecast period and twelve historical periods. A rolling total is calculated for each forecast version, which includes 13 forecast periods.

An offset of 1 period is used in the accuracy calculation. The offset plan is the last published forecast for the first period in each Forecast Versions row. These plan values are indicated in blue color in the chart for easy identification. The offset plan is not applicable for the current forecast period.

The Summary rows are included at the bottom of the table, with these values:

  • Offset Plan
  • Net History
  • Outlook
  • Accuracy

The accuracy calculated for the table is the percentage forecast of demand, rounded off to 2 decimal points and color coded based on the percentage value. This accuracy is calculated automatically whenever a planning entity moves to a new period and the table is updated with the latest accuracy calculation. You can export the accuracy grid data in excel format.

You can use the Data Series Comparison option to select a manual data series and view the related additional data in the Accuracy (slant) chart.

When you select a data series, these additional rows are displayed in the Accuracy table:

  • Data Series
  • Data Series vs History %
  • Data Series vs Offset Plan %
  • Z Chart
