Thierry Chassaing

Senior Partner & Managing Director

In general, it is very hard to duplicate the success of other retailers. This difficulty is part of what we call the iceberg effect: what you see on the shelves is just a small part of what a retailer does. There are many complex processes—such as category management, pricing, and promotions—that some retailers are better at than others, and superior execution can make a huge difference to the bottom line.
