    Summary of Scoring logic for predefined formulas for group factors

    Group factors in assessments can be scored using multiple predefined formulas, each determining how the scores from individual factors contribute to the overall group factor score. These formulas apply to factors with contributions marked as Qualitative, Quantitative, or Both. Qualitative scores can be optionally transformed based on selected criteria before weighting is applied.

    Key Features

    • Predefined Formulas: Users can select from Sum, Minimum, Maximum, Average, Product, and Weighted Average formulas to calculate group factor scores.
    • Score Contributions: Scores come from manual factors within a group factor, considering their contribution type (Qualitative, Quantitative, or Both).
    • Qualitative Score Transformation: If enabled, qualitative scores undergo a transformation before applying the group factor’s qualitative weighting.
    • Weighted Scoring: After transformation, qualitative scores are weighted by the group factor’s qualitative weighting percentage, affecting the final score.

    Formula Behaviors

    • Sum: Adds either qualitative or quantitative scores from the factors.
    • Minimum: Selects the lowest qualitative or quantitative score among the factors.
    • Maximum: Selects the highest qualitative or quantitative score among the factors.
    • Average: Calculates the mean of qualitative or quantitative scores.
    • Product: Multiplies qualitative or quantitative scores together.
    • Weighted Average: Divides the sum of qualitative scores by the sum of their weights, applying weighting to better reflect factor importance.

    Practical Implications for ServiceNow Customers

    Understanding and selecting the appropriate formula allows customers to tailor how group factor scores are calculated from constituent factors, ensuring assessment results align with organizational priorities and scoring methodologies. The ability to transform qualitative scores and apply weightings offers flexibility to fine-tune scoring to specific business contexts.

    Group factors have multiple predefined formulae and each of them has a specific contribution to the scoring logic.

    Predefined formulae scoring logic

    Users can select one of the following predefined formulae to calculate the scoring for group factors. The scores are contributed by scores of manual factors that comprise a group factor and have factor contribution as Qualitative or Quantitative, or Both.

    The qualitative scores calculated using the predefined formulae are transformed using the transformation criteria if the Transform qualitative score option is selected for the group factor.

    The qualitative scores calculated after transformation will be derived using the Qualitative weighting of the group factor. For example, if the calculated score is 10 and the Qualitative weighting is 50%, then the final score for group factor will be calculated as 10 x 0.5 = 5.

    Sum

    For Qualitative, this formula adds up the qualitative scores in an assessment instance. The scores are contributed by scores of manual factors that comprise a group factor and have factor contribution as either Quantitative or Both.

    For Quantitative, this formula adds up the quantitative scores in an assessment instance. The scores are contributed by scores of manual factors that comprise a group factor and have factor contribution as either Quantitative or Both.

    Minimum

    For Qualitative, this formula takes the minimum of qualitative scores in an assessment instance. The scores are contributed by scores of manual factors that comprise a group factor and have factor contribution as either Quantitative or Both.

    For Quantitative, this formula takes the minimum of quantitative scores in an assessment instance. The scores are contributed by scores corresponding to the factors that a comprise a group factor and have factor contribution of either Quantitative or Both.

    Maximum

    For Qualitative, this formula takes the maximum of qualitative scores in an assessment instance. The scores are contributed by scores corresponding to the factors that a comprise a group factor and have factor contribution of either Qualitative or Both.

    For Quantitative, this formula takes the maximum of quantitative scores in an assessment instance. The scores are contributed by scores corresponding to the factors that a comprise a group factor and have factor contribution of either Quantitative or Both.

    Average

    For Qualitative, this formula takes the average of qualitative scores in an assessment instance. The scores are contributed by scores corresponding to the factors that a comprise a group factor and have factor contribution of either Qualitative or Both.

    For Quantitative, this formula takes the average of quantitative scores in an assessment instance. The scores are contributed by scores corresponding to the factors that a comprise a group factor and have factor contribution of either Quantitative or Both.

    Product

    For Qualitative, this formula multiplies qualitative scores in an assessment instance. The scores are contributed by scores corresponding to the factors that a comprise a group factor and have factor contribution of either Qualitative or Both.

    For Quantitative, this formula multiplies quantitative scores in an assessment instance. The scores are contributed by scores corresponding to the factors that a comprise a group factor and have factor contribution of either Quantitative or Both.

    Weighted average

    For Qualitative, this formula divides the sum of qualitative scores in an assessment instance by the sum of weights. The scores are contributed by scores corresponding to the factors that a comprise a group factor and have factor contribution of either Qualitative or Both.
