    Key Features

    • Metric Types Mapping: Existing metric types are mapped to the Assessment Template fields, facilitating a streamlined transition.
    • Metric Categories Mapping: Categories are aligned to the Section table, maintaining their descriptions and order for structured assessments.
    • Metrics Mapping: Existing metrics are transitioned to the Question table, with fields like Allow additional information and Data type appropriately set.
    • Question Type Migration: All migrated Question records default to Text data type, with specific layouts for numeric scales.
    • Field Mapping: Existing fields are transitioned to relevant fields in the Question table, ensuring data integrity.
    • Template Definitions Mapping: Assessment template definitions are accurately reflected in the Choice table, preserving display text and order.

    Key Outcomes

    As a result of this migration process, ServiceNow customers can expect:

    • Improved organization of metrics within assessment templates, enhancing usability and clarity.
    • Consistent and accurate representation of legacy data, minimizing disruption during the transition.
    • Enhanced assessment capabilities through structured question types and improved user experience.

    Legacy metric types are migrated to specific sections in the assessment templates in the Smart Assessment Engine application.

    How metric types are mapped

    This tables shows the mapping used to move the existing metric types to the section in the assessment templates.

    Table 1. Metric types for assessment type
    Existing metric type Mapped to
    Name (Translated text) (Max length 255) Name (Translated text) field in the Assessment Template table.
    Description (Translated text) (Max length 1000) Description (Translated html) field in the Assessment Template table.
    Table (Table Name) Table (Table Name) field in the Context Item table.

    How metric categories are mapped

    This tables shows the mapping used to move the existing metric categories to the section table in the assessment templates.

    Table 2. Metric categories are mapped to the Section table
    Existing metric type Mapped to the Section table
    Name (Translated text) (Max length 255) Name (Translated text) field.
    Description (Translated text) (Max length 1000) Description (Translated text) field.
    Order (Integer) Order (Order Index) field.

    How metrics are mapped

    This tables shows the mapping used to move the existing metrics to the question table in the assessment templates.

    Table 3. Metrics are mapped to the Question table
    Existing metric type Mapped to the Question table
    Allow additional information (True/False) Enable justification (True/False) field.
    Data type (String) (Max length 40) Based on the Data type field value, the appropriate question type reference is added to the Question table. Data type is string.
    Details (Translated html) (Max length 8000) Guidance statement (Translated html) field.
    Question (Translated text) (Max length 512) Label (Translated text) field.
    Mandatory (True/False) Is mandatory (True/False) field
    Max (Integer) Max number (Decimal) field
    Min (Integer) Minimum number (Decimal) field
    Order (Integer) Order (Order index)

    How metric types are migrated to question types

    After migration, all Question records are set as data type Text.

    After migration, all Question records whose source metric is template/Numeric-scale are set with a response layout of Horizontal.

    This tables shows the mapping used to move the existing metric types to the question types in the assessment templates.

    Table 4. Metric type mappings
    Existing metric type Mapped to
    Attachment Attachment
    Choice Drop-down list
    Date Date
    Date/Time Date/Time
    Likert scale Radio button
    Multiple selection Check box
    Numeric scale Radio button
    Reference Reference
    Yes/No Radio button

    How fields are mapped

    This tables shows the mapping used to move the existing fields to the question table in the assessment templates.

    Table 5. Fields are mapped to the Question table
    Field in the existing table Mapped to the Question table
    Reference table Table field.
    Condition Filter condition field.

    How metric definitions are mapped

    This tables shows the mapping used to move the existing metric definitions to the choice table in the assessment templates.

    Table 6. Metric definitions are mapped to the Choice table
    Metric definition in the existing table Mapped to the Choice table
    Display Text label field in the Choice table
    Order Integer data type is mapped to the Order field in the Choice table that is based on the same ascending sequence of the template-definition records in the Value field that is associated with a particular template.

    How assessment metric templates are mapped

    Only templates where the Allow image field is set to false are migrated. No field mapping is done for this table.

    Metrics whose data type is template are migrated as questions of the type Radio button if the Allow image field is set to false at the template level.

    How assessment template definitions are mapped

    This tables shows the mapping used to move the existing template definitions to the choice table in the assessment templates.

    Table 7. Assessment template definitions are mapped to the Choice table
    Assessment template definition in the existing table Mapped to the Choice table
    Display Text label field.
    Value Integer data type is mapped to the Order field in the Choice table, based on the same ascending sequence of the template-definition records in the Value field that is associated with a particular template.
