Many demand planning solutions do not stand to theiroriginal premise (improving accuracy)
The typical phenomenon
Good accuracy on well behaved items that arealready well predicted by planners
Low accuracy on promoted/badlybehaved/cannibalized/new items that are
complicated to forecast
Result
The introduction of statistical forecasting does not
improve forecast accuracy when compared to themanual forecasting
The statistical forecasting fails to gain plannerstrustplanners revert to manual planning

It is not reasonable to expect the planner to apply judgmentsfor all items at all levels
It is not reasonable to expect the planner to optimize thebaseline forecast via statistical means

NWNA original problem statement
Arrive at the Right Level for Statistical Forecasting
Figure out the most accurate way for Dis-aggregation
Select the Prudent Model (that suits our data) which might-
Suggest the best Level to use APO automatic algorithmic selection
Identify a potential for a Composite Forecast Algorithm.
Propose a better- fit Algorithm
Indicate a need for ABC categorization
We look to achieve a DPA (Product / Location / Week) increase without impactingthe current CDP Process. We need an empirical input for our direction forward.

Forecasting solutions approaches in demand planning
Automatic systems - produce full forecast using a completemodel (including all relevant information).
Semi automatic systemsproduce mostly baselines. Humaninterventions are required to complement the forecast withpromotions, cannibalizations, etc.
Toolbox systemprovide planners tools to produce statisticalforecasts if they wish to do so

The challenge
Moving from the old fashioned planner based forecasting to anautomated process where the planner intervenes only in places theycan provide real benefits.
5/23/2018 Nestle Waters Forecasting Improv Ment Slides

How to improve results? The positive planning cycle summary
Define the needs and the proper objective functions to reflectthem
Produce fully automatic highest accuracy rich forecasts
define cleansing, event handling and forecasting strategiesUse segmentation tools to distinguish between excellent,good and bad forecasts
Insure acceptance of the better forecasts, limit the influenceof bad forecasts
Avoid deterioration by making the inspection loop an integral
part of the operational process and by re-optimizing theresults

Bias: coverage of sales - required for inventory
and capacity management
Distance: lower the error for (?) periods using
some sort of error function
Structure: look right, behave the same way that
past data behave ( different from distance
because measured in the future and not on the
past.
Stability: should not change much from period
to period unless something really changes
(otherwise disturbers enrichments)

Working with planners
Th Ch ll
5/23/2018 Nestle Waters Forecasting Improv Ment Slides

The Challenge
1. Combine statistical forecasts and planners work
2. Make planners understand the automatic results
3. Help planners accept the statistical results and understand theirusefulness
4. Define clear separation between work to be done by thesystem and work to be done by planners
33
Methodology
5/23/2018 Nestle Waters Forecasting Improv Ment Slides
34/37
Methodology
1. Create an optimized baseline for all levels
2. Use statistical proportional factors to define relations inside thehierarchy trees
3. Isolate areas where statistical forecast is better
4. Use statistical forecast proportional factors to drive planningdecisions to distribution decisions
1. from planning level (Material group @ trade partner) to distributionlevel (material @ location)
5. Measure success of statistical forecast and compare to finalforecast
6. Measure acceptance and confidence in statistics and sharewith planners

Executive Summary
A new forecasting methodology and procedure was deployed by during summer 2010
The procedure improved forecast accuracy at location level by an estimated 15%
The rate of inventory turns grew and money tied up in inventory was reduced from an average of
21M to around 18M.A nominal annual cost saving of $2-3 million was realized.
Successful forecasting was instrumental in quickly adjusting inventory levels to the coldersummer of 2011.
An upgrade, introduced in July 2011 (Ogentech 1.5), improves Canada accuracy results byaround 10%
Constant maintenance, monthly exceptions detection, and re-optimization of the paradigm
periodically insures maintaining these results.The maintenance adapts the statistical tools to the changing dynamics of trade partners, trendsand weather effectsthis prevents the familiar phenomenon of deterioration in statisticalforecasting that eliminates the benefits after few months.
The correctness of statistics allows planners to concentrate on changes and react better tomarket demands
The current service level by Ogentech is expected to continue to deliver cost savings of around3-4M per year
