Num mundo cada vez mais de classificações, escalas e tabelas comparativas, a Hannaford, uma cadeia de supermercados implantado no Nordeste dos EUA, está a criar valor para os seus clientes através da adopção da classificação por estrelas a 25500 dos seus produtos:
The system that hannaford developed, called Guiding Stars, rated the nutritional value of the grocery items in the store on a scale of zero to three stars, with three representing the most nutritious products.
After analyzing a year’s worth of sales data, Hannaford found that customers tended to buy leaner cuts of meat. Sales of ground beef with stars on their labels increased 7 percent, and sales of chicken that had a star rating rose 5 percent. Sales of ground beef labeled with no stars dropped by 5 percent, while sales of chicken that had a zero-star rating declined 3 percent.
