General Description

The KPI Forecast Accuracy (FA) evaluates the ability to get a visibility on customers' demand in terms of quantity.
As an input of S&OP process, reliable forecasts constitute the major way to improve the customer satisfaction via an optimized planning of operations. The Forecast Accuracy in this dashboard is calculated based on the Final Forecast and the Gross History. 
For a particular month, the Forecast Accuracy is calculated for the last 5 months forecast (M-1 ... M-5); allowing the possibility to evaluate the accuracy of the forecast with reference to several different forecast periods.
The refresh of the KPI is made every month on the 7th, including the full history.
It is available for all GBUs currently using Dynasys or APO as Demand Planning systems: Aroma Performance, Composite Materials, Novecare, Peroxides, Silica, Soda Ash&Derivatives, Special Chem and Technology Solutions.

Key figures

Weighted Forecast Accuracy: In addition to the Standard Forecast Accuracy, a second method for calculating the Forecast Accuracy is available.
This measure weights the Forecast Error based on the Gross History of the selected month, according to the selected level of aggregation.


Weighted Forecast Accuracy = Sum[Max(0; 1- Abs((Final Forecast - Gross History)/ Gross History))1MonthWeight] / [Sum Gross History 1MonthWeight] x 100


12 levels of aggregation are available, and the calculation is made dynamically depending on the selected level:
1.Material / Ship Destination / Distribution Channel
2.Product
3.Product / Ship Destination Zone / Group of Activity
4.Product Hierarchy
5.Product / Plant
6.Ship Destination Country
7.Ship Destination Zone / Sales Rep
8.Sales Rep / Product / Ship-to-KA
9.GBU Product Family
10.GBU Zone / Ship Destination Country / Ship Destination (Plant)
11.GBU Zone / Ship Destination Country / Tactical Material
12.GBU Zone / Ship Destination Country / Product Hierarchy

Standard Forecast Accuracy: This figure measures the gap between the Gross History and the forecasted quantities. To have a better representation of the forecast error, an absolute value of the forecast error is calculated.
This is also called the Mean Absolute Percentage Error (MAPE).


Standard Forecast Accuracy = Max(0; 1- Abs((Final Forecast - Gross History)/Gross History)) x 100

Forecast Accuracy = 100%, it means there is no gap between the Forecast and the Gross History
Forecast Accuracy = 0%, it means inaccurate forecasts
Forecast Accuracy Month-2 is the time between produced forecast and the Gross History (FA June M-2: means forecasts done in April)


Forecast Bias ratio (%): It measures the tendency for a forecast to be consistently higher or lower than the actual value.
Forecast Bias is distinct from the forecast error, in that a forecast can have any level of error, but still be completely unbiased. It is calculated as the average deviation (over or below) of forecasts from actuals.

Forecast Bias = Sum(Final Forecast)-Sum(Gross History)/Sum(Gross History) x 100


If the Forecast is greater than the Gross History, then the Forecast Bias is positive (indicates over forecast)
At the opposite, if the Forecast is lower than the Gross History, then the Forecast Bias is negative (indicates under forecast)
A Forecast Bias = 0, indicates a total absence of gap (bias)
Forecast Bias is a “tracking signal” (positive or negative) and percentage can be above 100%
In many cases, it is useful to know if demand is systematically over- or under-estimated. For example, even if a slight forecast bias would not have a notable effect on store replenishment, it can lead to over- or under-supply at the central warehouse or distribution centers if this kind of systematic error concerns many stores.

GBU Prod. Family = by default the Product Family, but also the Product Hierarchy, the GBU Material Group, or the Forecasts Family
GBU Zone = Mini-Zone = Group of Countries, Specific by GBU
Packaging Type = used on a material
Product Group (PGMI) = Group of products from Dynasys
Product Line 00 = Attribute of a material. There are 6 differents product line levels, corresponding to differents aggregations of products

How does it work?

1. Select Filters
On top of the dashboard, several different filters allow you to reduce the scope of data for the analysis

as well as Specific Filters to select in the dedicated box


2. Select the Forecast Accuracy calculation method
As explained above, the Forecast Accuracy is calculated according to:
    • the standard calculation at the detailed level Material x Distribution Channel x Ship-to
    • the weighted calculation at selected level within the 12 available ones in the drop-down menu (dynamic calculation at displayed level)
3. Select the reference period
On every 6th of each month, a snapshot of the Forecast is taken, keeping the reference of the forecast provided up to 5 months before. This will allow to calculate the FA for periods M-1, M-2, M-3, M-4, and M-5.
Click here to retrieve the naming conventions by system
4. Check the Forecast Accuracy table
After applying the filters, selecting an aggregation level and a reference period, there is still a way to customize a detail table with the desired Indicators and Dimensions
Please note that all dimensions don't match with all aggregation levels.
As a consequence, only the dimensions that are available for the selected aggregation level are displayed.
Mismatching dimensions are disabled to avoid calculation errors.
In the custom table, dimensions in the cyclic depend on the selected aggregation level. If a column is displayed twice because of the cyclic, just deselect the corresponding dimension in the table.
In the pivot table format (Click on the Fast change if you don't see it), the total is available for the 1st column. Move your columns to get the total for the dimension you wish.
