Seasonal Demand

This project introduced a demand planning solution for products with a highly seasonal demand pattern. The usual steps in a demand planning process were implemented: gather realizations from the ERP system, remove outliers, generate statistical forecast and add inputs from the various departments like Sales and Marketing to come to a Final Demand plan. Specific to this project were the aggregation of individual customers to customer groups to prevent a huge number of planning combinations and the possibility to use the more stable seasonal demand pattern at product group level as starting point for the product level forecast as alternative for the statistical forecast generated at product level. Final demand available in monthly buckets in Demand planning was disaggregated to weekly buckets when transferring to supply planning.
