Modify forecast parameters to visualize forecast data

Configure and tweak forecast parameters to see how the forecast behaves when you vary the period length, periods to forecast, or algorithm. You can view the modified forecast on the time-series visualization.

Before you begin

Role required: sn_agent_forecast.admin and sn_wfo_itsm.manager

The user with these roles must also be a manager of the assignment group that is associated with the resource conversion formula.

About this task

You can define the start and end dates for which you want to visualize the forecast data. The start date for a forecast configuration is based on the number of historical days you want to consider for data visualization. This is set using the sn_agent_forecast.number_of_historical_days_in_timeseries_chart property.

The default start date is set to 90 days ago starting from the day before the current day. The end date is calculated based on the period length and the periods to forecast represented in days. For example, if the period length is 7 days and the periods to forecast is 5, then the end date is 35 days including the current day.

Procedure

1. Navigate to All > Workforce Optimization for ITSM > Manager Workspace.
2. Click the Schedule icon .
3. Click Forecasts.
4. Select the forecast model for which you want to view the time-series data.
   You can visualize each of the forecast parameters that were created for the forecast model.
5. Click the gear icon .
6. Click the plus (+) sign.
7. Configure the forecast parameter.
   1. From the Period length unit list, select the unit for the length of the period to forecast.
   2. In the Period length field, enter the length of a season to forecast.
   3. In the Periods to forecast field, enter the number of seasons, which is the period length, for which you want to forecast.
   4. In the Algorithm field, select an algorithm you want to use to calculate the forecast.
   5. Click Update.

   The forecast is created in Draft state. The forecast is calculated and displays in the forecast model. You can analyze the forecast with the new forecast parameters before you publish it.
8. To preview a forecast before publishing it, click Preview.
   The forecast is calculated using the algorithm and parameters configured in the forecast parameter. When you create a manual adjustment to predict future resources, Demand Forecast overlays the adjustment in the time-series chart.

   When you	Then the forecast
   Unpublish a published forecast	Become inactive.
   Preview an inactive forecast parameter	Displays for the date range for which the forecast parameter was active.
   Preview an active forecast	Displays the time-series data for the future time-period.

9. Publish the forecast parameters.
   1. To publish a newly created forecast parameter, click Save and then click Publish.
   2. To publish an active forecast parameter, click Publish.

   Note:

   You can only have one forecast in Published state, which is used to calculate the resources.
   When the forecast parameter is published:

   • The state of the record changes to Published.
   • The Forecast resources for future job runs daily and uses the published forecast parameters to calculate the agent forecast. The calculation uses the resource conversion formula to calculate the forecast data from the current point forward. You can view the updated resources in the team calendar.
   • Any other forecast parameters that were created would be unpublished and inactive.
