This image depicts the layout of a Sainsbury's store. Sainsbury's Supermarkets Ltd operates a supermarket chain in the United Kingdom, with a 16.9 percent UK supermarket sector market share. All of the outlets follow the Sainsbury Store layout. People at the client company believed that goods placed "first-in-flow" (i.e., the first items customers saw and purchased) sold more. They reasoned that shifting a section from last-in-flow to first-in-flow would boost its sales. One of the most crucial aspects of this work was designing the store layout – deciding where all of the different types of goods should be located within the store. The layouts of the chain's supermarkets were already quite different.
