Concept: Calculating the VIBE Score

Representation is the percentage of active headcount in each intersection at the end of the period. Representation is the parity benchmark that drives the scoring in the VIBE Index.

Formula: Representation of [Intersection] = (Active headcount for intersection at end of period / Total active headcount at end of period) * 100

Example: Representation of Female - White = (2000 / 8600) * 100 = 23.3%

The Parity View is the proportional value of a given outcome metric for a given intersection.

Formula: Parity View for [Outcome Metric] in [Intersection] = (Metric Total for Intersection / Metric Total) * 100

Example: Parity View for Promotions in Female - White = (400 / 1593) * 100 = 25.1%

The Parity Benchmark for a given intersection is the level of success in percent for all outcome metrics after incorporating the default threshold of 3%.

The threshold sets the acceptable range by which we can score an intersection as a success for a given outcome metric. The default threshold of 3% relaxes all success criteria by 3%.

Formula for most outcome metrics (Hires, Leadership, Promotions, Belonging): Parity Benchmark for [Intersection] = Representation * (100 - Threshold) / 100

Example: Parity Benchmark for Female - White = 23.3 * (100 - 3) / 100 = 22.6%

Formula for the outcome metric Attrition: Parity Benchmark for [Intersection] = Representation * (100 + Threshold) / 100

Example: Parity Benchmark for Female - White = 23.3 * (100 + 3) / 100 = 24.0%

The Parity Definition states whether or not a given outcome metric is a success for a given intersection.

To determine the parity definition for most outcome metrics (Hires, Leadership, Promotions, and Belonging), we compare the parity view to the parity benchmark for the intersection. 1 is a success, zero is below parity.

Formula for most outcome metrics (Hires, Leadership, Promotions, Belonging): Parity Definition of [Outcome Metric] for [Intersection] = IF ((Parity View) >= (Parity Benchmark) , 1, 0)

Example: Parity Definition of Promotions for Female - White = IF (25.1 >= 22.6, 1, 0) = 1

For Attrition, we compare the attrition parity view to the parity benchmark for attrition. 1 is a success, zero is below parity.

Formula for the outcome metric Attrition: Parity Definition of Attrition for [Intersection] = IF ((Attrition Parity View) <= (Parity Benchmark for Attrition), 1, 0 )

Example: Parity Definition of Attrition for Female - White = IF (18.8 <= 24.0, 1, 0) = 1

An outcome score is the total number of successes for a given outcome metric, scaled to align with the VIBE Score range.

The raw outcome score is the sum of the successes of all intersections minus 1.

We subtract 1 from the sum because the outcome metric parity view for at least 1 intersection must always be at or above the intersection representation (for attrition, at least 1 intersection must always be at or below the intersection representation). Subtracting 1 also resets the scale of the score to have a minimum of 0 to be consistent with the VIBE Score range.

If the parity view for a given outcome metric is unattainable, we don't calculate the outcome metric score and we exclude the metric from the VIBE Score calculation. As a result, the Outcome Scores card doesn't display the excluded outcome metric and the Parity Matrix displays a dash for all intersections in the corresponding outcome metric column. Example: If there were no terminations in the last 12 months, the outcome metric Attrition is unattainable. Therefore, we don't include the outcome metric Attrition in the VIBE calculation.

Formula: Raw Outcome Score for [Outcome Metric] = SUM ((Success Count Intersection 1), (Success Count Intersection 2), (Success Count Intersection 3), ...) - 1

Example (for 5 intersections): Raw Outcome Score for Hires = SUM (1 + 1 + 0 + 1 + 1) - 1 = 3

Scaling the raw outcome score ensures that each outcome score is on a scale of 0 - 5 to align with the VIBE Score range.

Formula: Scaled Outcome Score for [Outcome Metric] = (Raw Outcome Score) * (5 / ((Number of Groups) - 1))

Example (continued): Scaled Outcome Score for Hires = 3 * (5 / (5 - 1)) = 3.75

A group score is the total number of outcome metric successes for a given intersection, scaled to align with the VIBE Score range.

Formula: Raw Group Score for [Intersection] = SUM ((Attrition Parity Definition), (Hires Parity Definition), (Leadership Parity Definition), (Promotions Parity Definition), (Belonging Parity Definition))

Example: Raw Group Score for Female - White = SUM (0 + 1 + 1 + 0 + 1) = 3

Scaling the raw group score ensures that each group score is on a scale of 0 - 5 to align with the VIBE Score range.

Formula: Scaled Group Score for [Intersection] = Raw Group Score * (5 / (Number of Outcome Metrics))

Example: Scaled Group Score for Female - White = 2 * (5 / 5) = 2

The VIBE Score ranges from 0 to 5 and is the arithmetic average of the overall outcome score and the overall group score.

The VIBE Score is sensitive to the magnitude of the group and outcome scores and the variance among these scores. This means that the VIBE Score is higher when intersections have higher group scores, outcome scores are higher, and there's less overall variance among group scores and among outcome scores (greater equity).

To get the overall outcome score or the overall group score, we add 1 to each individual score. This prevents multiplication by a value that is less than 1. We then multiply the individual scores and subtract 1 from the resulting value. This sets the score on a scale of 0 - 5 to align with the VIBE Score range.

Formula: Overall Outcome Score = (PRODUCT ((Each Scaled Outcome Score) + 1)) ^ (1 / (Number of Outcomes)) - 1

Example: Overall Outcome Score [Hires, Promotions, Leadership, Attrition, Belonging] = ((3 + 1) * (3 + 1) * (1 + 1) * (2 + 1) * (3 + 1)) ^ (1 / 4) - 1 = 2.29

Formula: Overall Group Score = (PRODUCT ((Each Scaled Group Score) + 1)) ^ (1 / (Number of Intersections)) - 1

Example: Overall Group Score [Female - Asian, Female - URM, Female - White, Male - Asian, Male - URM, Male - White] = ((3.75 + 1) * (2.5 + 1) * (2.5 + 1) * (2.5 + 1) * (1.25 + 1) * (5 + 1)) ^ (1 / 6) - 1 = 2.74

The arithmetic average of the overall outcome score and the overall group score is the VIBE Score for your organization.

Formula: VIBE Score = AVG ((Overall Outcome Score) , (Overall Group Score))

Example: VIBE Score = AVG (2.29, 2.74) = (2.29 + 2.74) / 2 = 2.52
