Formulas for Scoreboard Calculations

The most important type of scoreboards is the Favorite View-based scoreboards. You define Favorite View-based scoreboards by using a Favorite View for data selection and drill-down settings. A Favorite View specifies key filtering, AUM, measures to include, time range, calculated measures, and other settings. The Favorite View also provides configuration for how the pivot sheet looks when you drill down from a scoreboard.

This table shows the different formulas based on Favorite View for calculating scoreboards in M3 DMP:

Formula Description
1 – Difference versus Base Detects hits inside or outside an interval for formula 1 - Difference versus base of two measures. It is used for calculating Forecast Percentage Accuracy

1-(([M1] - [M2]) / [M1]) >= 0 AND 1-(([M1] - [M2]) / [M1]) <= 0

Change Interval Used to calculate the Change Interval  of a single measure compared to the measure without changes

(M(Pr+Poff)*F1 <<=>>= (M(Pr) + C(Pr)) <<=>>= M(Pr+Poff)*F2)

Compare Measures Used to calculate and compare two measures against each other

(M2(Pr-Poff)*F1 <<=>>= M1(Pr) <<=>>= M2(Pr-Poff)*F2)

Compare Periods Used to calculate  and compare values of one measure in different periods

(M (Pr-Poff)*F1 <<=>>= M(Pr) <<=>>= M (Pr-Poff)*F2)

Difference Used to calculate the difference between two measures inside or outside a value interval

(L1 <<=>>= M1(Pr)-M2(Pr-Poff) <<=>>= L2)

Difference versus Base Used to calculate the Difference versus Base of two measures

(L1 <<=>>= (M1(Pr) - M2(Pr-Poff))/M1(Pr) <<=>>= L2)

Difference versus Subtrahend Used to calculate the Difference versus Subtrahend of two measures

(L1 <<=>>= (M1(Pr) - M2(Pr-Poff))/M2(Pr-Poff) <<=>>= L2)

Difference versus Sum Used to calculate the Difference versus Sum of two measures inside or outside a value interval

(L1 <<=>>= (M1(Pr) - M2(Pr-Poff))/M1(Pr) + M2(Pr-Poff) <<=>>= L2)

Forecast Alarm 1 Used to calculate the Forecast Alarm type 1

See About Forecast Alarms.

F1*MAD <<=>>= |M1(Pr) - M2(Pr-Poff)| <<=>>= F2*MAD)

Forecast Alarm 2 Used to calculate the Forecast Alarm type 2

See About Forecast Alarms.

F1*MAD <<=>>= Avg(n,M1(Pr) - M2(Pr-Poff)) <<=>>= F2*MAD)

Interval Used to calculate a measure inside or outside a given value interval

(L1<<=>>=M(Pr) <<=>>= L2)

Square Difference Used to calculate the Square Difference between two measures inside or outside a value interval

(L1 <<=>>= (M1(Pr)-M2(Pr-Poff))^2 <<=>>= L2)

Square Root Difference Used to calculate the Square Root Difference between two measures inside or outside a value interval

(L1 <<=>>= Sqr((M1(Pr)-M2(Pr-Poff))^2) <<=>>= L2)

Sum Used to calculate the sum of two measures inside or outside a value interval.

(L1 <<=>>= M1(Pr) + M2(P-Poff) <<=>>= L2)

Tracking Signal Special formula with Sum of differences of two measures over several periods divided by Average of the same the difference for the same number of periods

The formula detects if tracking signal lies outside approximately the standard deviation.

Sum(2,([M1] - [M2])) / Avg(2,Abs(([M1] - [M2]))) >= 0 AND Sum(2,([M1] - [M2])) / Avg(2,Abs(([M1] - [M2]))) <= 0

Formula Templates

In addition to the above-mentioned formulas, M3 DMP includes several Key Performance Indicators (KPIs)..

This table shows a set of predefined formulas you can use to define the KPIs.

Formula Description
Forecast Percentage Accuracy Forecast accuracy measures how close the actual quantity is to the forecasted quantity. The content varies by the type of business and the data that is available. The mathematical calculation is (forecast sales − actual sales) / forecast sales.
Forecast Percentage Error

Forecast error is the converse of accuracy:

Error (%) = 1 – Accuracy (%)

Accuracy is normally constrained to be between 0 and 100% meaning error > 100% => 0% accuracy and error close to 0% => increasing forecast accuracy.

Forecast Error Forecast error is the difference between the actual quantity and the forecasted quantity.
MFE - Mean Forecast Error The Mean Forecast Error is the Average of the Sum of signed Forecast errors. It is identical with BIAS.
BIAS - Mean Forecast Error Forecast Bias is the Average of the Sum of signed Forecast errors. It is identical with MFE.
MAD - Mean Absolute Deviation The absolute average deviation. The figure does not say much. We recommend using MAPE, MFE, or BIAS instead.
MAPE - Mean Absolute Percentage Error MAPE or the absolute percent error is a decent cross-sectional measure to evaluate divisional or corporate performance across many SKUs. It is used to measure the SKU level forecast error in most supply chains.
MSE - Mean Squared Error MSE is a better measure for calculating safety stock and other inventory planning parameters. The MSE has basic statistical properties and therefore used to interpret service levels as the number of standard deviations in a standard normal distribution.
RMSE - Root Mean Squared Error RMSE is a good longitudinal measure across time. You can use RMSE to compare error over time for the same SKU as it is also used typically to set safety stock planning.
Tracking Signal The formula detects if Tracking signal is used for accumulating errors over time to detect when the basic pattern has changed.
Accuracy Signal

The Accuracy Signal is used for practical follow up on the forecast quality.

(Forecast – Actual) / (Forecast + Actual)

In addition to measuring the Forecast accuracy, the Accuracy Signal also provides information about how to improve the forecast.

Theils U-statistic

Theils U-statistic provides a relative comparison of two measures, including weighing of error severity.

If U = 1, then the Naive Method is as good as the current Forecast Method.

If U < 1, then the Forecasting Method is better than the Naive Method

If U > 1, then the Naive Method is better than the Forecasting Method. You do not waste time applying further Forecasting methods.
