    Summary of AI Readiness Evaluation system properties

    The AI Readiness Evaluation system properties allow ServiceNow customers to customize and control various aspects of their AI readiness assessments across multiple modules such as ITSM, CSM, HRSD, AI Search, and Virtual Agent. These properties are stored in theSystem Property [sysproperties]table and enable fine-tuning of assessment performance, visibility, scheduling, effort estimation, and threshold criteria to ensure accurate and efficient readiness evaluations.

    Key Features

    • Assessment Performance Control: The snassess.assessmentlimit property limits the volume of data assessed to reduce performance issues, with a default of 10,000 records.
    • Effort Visibility and Customization: The snassess.effortvisibility property toggles the display of remediation effort estimates on assessment dashboards. When enabled, users can customize remediation efforts in days and update assessments accordingly.
    • Scheduled Job Enablement per Module: Properties such as snassess.va, snassess.itsm, snassess.csm, snassess.hrsd, and snassess.aisearch control whether scheduled jobs run for their respective AI assessments, allowing administrators to enable or disable data generation for each module.
    • Virtual Agent Prerequisites: For the Virtual Agent assessment job to run, specific plugins must be enabled, including Virtual Agent and Catalog Conversational Coverage.
    • Status Threshold Configuration: The snassess.Threshold property defines the percentage threshold (default 75%) used to determine if a module’s readiness status is "Good" or "Action Required," ensuring accurate status indicators on the home page.
    • Remediation Effort Calculation: The snassess.TShirtMetric and snassess.TShirtSize properties work together to assign numeric effort values and map labeled effort sizes (Small to XXL) to days. These drive the remediation effort estimates shown across the application and must be kept in sync for accurate display.
    • ITSM Task Processing Limit: The snassess.tasklimit property limits the number of ITSM records processed per assessment to avoid performance degradation, with a default of 50 records.

    What Customers Can Expect

    • Improved control over AI readiness assessments, with options to optimize system performance and schedule assessment jobs per module.
    • Visibility and customization of remediation effort estimates to better plan and prioritize AI adoption efforts.
    • Accurate readiness status displays driven by configurable thresholds to reflect true assessment outcomes.
    • Support for modular assessment enabling, allowing customers to tailor evaluations to their specific ServiceNow environment and AI initiatives.
    • Guidance on prerequisites and configuration settings necessary for running assessments, particularly for the Virtual Agent module.
    • Protection against system performance impacts by setting appropriate limits on data volumes processed during assessments.

    Use system properties to customize your readiness assessment results. Access these properties from the System Property [sys_properties] table.

    Table 1. AI Readiness Evaluation system properties
    Property Description
    sn_assess.assessment_limit Reduce performance issues when a large volume of data is assessed. Adjust this system property, if needed, so that the job can run successfully. The default value is 10000.
    sn_assess.effort_visibility Control whether remediation effort estimates appear on the AI Readiness Evaluation.The default value is false. When this system property is set to true, both assessment tabs display effort cards and finding cards. The Remediation properties tab appears on the dashboard where you can customize estimated remediation efforts. All input values represent estimated remediation efforts in days. After making changes to the estimated remediation efforts, select Save, and then re-run the assessments to see the updated remediation efforts reflected.
    sn_assess.va Enables or disables the scheduled job for the AI Assessment - Virtual Agent. Set to true to enable, or false to disable. The default value is true. If set to false, the scheduled job will not run and no Virtual Agent assessment data will be generated. For the Virtual Agent assessment to run, the following prerequisites must all be met:
    • Virtual Agent (com.glide.cs.chatbot) must be enabled on the instance.
    • Catalog Conversational Coverage (sn_catalog_con_cov) must be active. This plugin is installed with ServiceNow Otto for Conversational Catalog Request (sn_now_assist_cr), which is included with ServiceNow Otto for Platform (sn_genai_platform).
    sn_assess.itsm

    Enables or disables the scheduled job for the AI Assessment - ITSM. The default value is true. If set to false, the scheduled job will not run and no ITSM assessment data will be generated.
    sn_assess.csm

    Enables or disables the scheduled job for the AI Assessment - CSM. The default value is true. If set to false, the scheduled job will not run and no CSM assessment data will be generated.
    sn_assess.hrsd

    Enables or disables the scheduled job for the AI Assessment - HRSD. The default value is true. If set to false the scheduled job will not run and no HRSD assessment data will be generated.
    sn_assess.ai_search

    Enables or disables the scheduled job for the AI Assessment - AI Search. The default value is true. If set to false, the scheduled job will not run and no AI Search assessment data will be generated.
    sn_assess.Threshold

    Defines the percentage threshold used to evaluate assessment results on the AI Readiness Evaluation home page, determining whether the status is displayed as Good or Action Required. The default value is 75% for all modules (ITSM, AI Search, CSM, Virtual Agent, and HRSD). If not set correctly, status indicators may be inaccurate.
    sn_assess.TShirtMetric

    Assigns numeric effort values to specific issue types and customizations, which power the remediation effort calculations displayed throughout the application. The default value is a JSON configuration. If modified, effort calculations will reflect updated values after the next assessment run. Review sn_assess.TShirtSize at the same time — if the two are out of sync, displayed effort estimates can may be inconsistent. If this property is not set, the system can't calculate remediation effort.
    sn_assess.TShirtSize

    Maps T-shirt size labels to effort in days. The default values are: Small = 5 days, Medium = 10 days, Large = 30 days, XL = 90 days, and XXL = 180 days. These mappings appear in effort pills and the Legends in the AI Readiness Evaluation dashboard. Review sn_assess.TShirtMetric at the same time when customizing. If not set correctly, effort pills will not display accurate effort in days and the Legends may show incorrect or missing information.
    sn_assess.task_limit

    Decides the maximum number of records to process for the ITSM assessment. The default value is 50. Be cautious about setting a higher limit or leaving the value empty because that would fetch all active records which could impact performance.
