WHAT CHANGED - TOTAL MARKET
FIRST RESULT COMBINATION
Carrefour lost 10% sales in UAE.
Chocolate Confectionary grew by 5%.
Excluding UAE and Chocolate, Carrefour lost 5%.
The first waterfall first item is the loss of Carrefour in UAE. A significant item both in terms of absolute dimension (larger than total variance) and in terms of % change (-10% vs the market's -1%). Chocolate growth is also noteworthy especially in absolute terms - 900k. The loss of Carrefour in the other markets and categories is "only" -5%.
SECOND RESULT COMBINATION
Petfood did well, up 28%
excluding Petfood, Carrefour lost 5% across the entire market
The second waterfall focuses on the category dimension and draws attention to Petfood that has gained 800k and 30% of sales. The second result is the loss of Carrefour in all markets - a hefty -1.4M falling at -5%.
The third and forth results are interesting: they show how an increase in Lulu culinary regular sales was almost 1 to 1 offset by a loss of all other Lulu sales.
THIRD RESULT COMBINATION
Petfood was up 36% in Carrefour
Excluding Petfood, Regular sales in Carrefour were down 3%
Promotion sales across all retailers were down 12%.
The third waterfall shows how the unfortunate Carrefour is the champion of petfood (+36%), but lost significantly in regular sales of other products.
FORTH RESULT COMBINATION
Carrefour's loss was a matter of price.
The forth waterfall splits variance between volume and price. We learn that the loss of Carrefour is practically all in price, and little in volume.
WHAT CHANGED - NESTLE'
FIFTH RESULT COMBINATION
Nestlé gained about one point of share because of better non promo sales in Oman in Carrefour.
Nestlé lost about one point of share because of worse promo sales in Oman and of worse promo and because of no promo sales in the other markets in Carrefour.

SIXTH RESULT COMBINATION
Non promo Confectionery sales went well for Nestlé in Carrefour in Oman.
Other no promo sales at Carrefour were weak.
Petfood was good across the board for Nestlé.

'Mparanza uses variable dimension variance to help find patterns in the data that could be missed with a traditional slice and dice approach.
Here are a set of products, retailers and markets that "explain" what changed for Nestlè.
The seventh waterfall shows how much of the change of Nestle' sales can be explained with two combinations of new offerings that did not exist the year before and with three combinations of lost offerings that do not exist in the most recent year.
