Determine the Estimated Time to Resolve a Case (ETTR) for a case by analyzing
similar closed cases in the past for better visibility and transparency.

Machine learning predicts the estimated time to resolve a case (ETTR) based on attributes
of a case such as its short description, category, priority, assignment group, and so
on. For more information about configuring the machine learning regression solution
definition for ETTR, see [HR PIWB template: Recommend estimated time to resolve](https://servicenow-prod.fluidtopics.net/3uVivxTiHCN9Z5Iwh4zBUA "Train your solution by using historical data to predict numeric outputs based on the historic data. Configure the solution definition to predict the estimated time to resolve a HR case.")

To make predictions, you can use the existing ETTR solution definition or change some of
the default settings such as the fields, a filter, and the training frequency.  
By analyzing the resolution time for similar closed cases in the past, the ETTR capability offers the following benefits:

* Gives employees better transparency and set expectations on resolution time for their cases.
* Helps agents in prioritization of work and measure performance.
* Provides data that can help managers with insights into SLA management and estimated time to resolve for cases.

## ETTR for HR Cases {#train-model-ettr__section_sm5_l14_jnb}

On configuring Estimated HR Case Resolution Time (ml_sn_sn_hr_core_global_hr_case_resolution_time) and training the predictive model, you can see the HR Case Resolution Time option. See the Estimated time to resolve value from:

* Employee portal view and Now Mobile view
* Agent workspace
* Platform view with a list of cases
* Case configuration view for admins

## ETTR predictive model {#train-model-ettr__section_tm5_l14_jnb}

The Estimated HR Case Resolution Time (ml_sn_sn_hr_core_global_hr_case_resolution_time) is configured and the predictive model is auto trained when all the following conditions are met:

* The Human Resources Scoped App: Core (com.sn_hr_core) plugin is installed.
* The Predictive Intelligence for Contextual Search (com.snc.contextual_search_ml) plugin is installed.
* The glide.platform_ml.auto_training.enabled system property is set to true.

{#train-model-ettr__ul_um5_l14_jnb}  
Business rules and system properties  
Verify the following system properties and business rules:

* Use or configure the following system properties and corresponding values to display the ETTR values per your requirement:
  * ml_sn_sn_hr_core.COE_ETTR_display_agent
  * ml_sn_sn_hr_core.COE_ETTR_display_employee
  * ml_sn_sn_hr_core.estimated_resolution_time_confidence_level
  {#train-model-ettr__ul_ypd_2gz_1qb}
* Use or configure the Predict Estimated Resolution Time business rule per your business needs.
{#train-model-ettr__ul_xct_hhb_bqb}

## ETTR model {#train-model-ettr__section_szk_ndg_ypb}

Regression solutions such as ETTR enable you to predict a point estimate and prediction interval. This capability informs the agent, employee, and service owners on the estimated resolution time for a case based on the time taken to resolve similar issues historically.

* Actual resolution time: Stores the actual time of resolution of a particular case. This field stores the resolution time from opening to closing of the case.  
  Nota:  
  When you upgrade, run this Populate Actual Resolution Time schedule job once for populating the actual resolution time for existing HR cases. For all upcoming cases, the business rule Populate Actual Resolution Time automatically generates the resolution time.
* Max ETTR: Indicates the maximum estimated resolution time in days for case completion. Estimate is based on the time taken for resolving similar HR cases.
* Min ETTR: Indicates the minimum estimated resolution time in days for case completion. Estimate is based on the time taken for resolving similar HR cases.
* ETTR in days: Stores the point estimated resolution time in days for case completion.
