reduction in stocks (especially end of season stocks for seasonal products)
improvement of quality of service (% of demand met)
improvement of the communication and collaboration between all the actors of the Supply Chain (especially between the forecasting department and the sales force)
Return on Investment obtained: almost 2% of the Turnover in gross margin per year!

demand forecast, especially optimized according to the types of articles and the modes of marketing
transformation of the demand forecasts into a supply plan, especially optimized in the respect of the usual suppliers constraints of the sector.
The performances usually observed are indeed:
reduction from 25 to 50% of the non delivered demand
reduction from 25 to 50% of remaining stocks at the end of the season (for seasonal products)
reduction of the supplied quantities (= reduction of the expenditure of purchase for traded products)
better valorization of final stocks at the end of the season from a better balance of the remaining sizes per style and color (there remain more central sizes and less extreme sizes)
Total optimization thus obtained generates the return on investment in less than one season.
