Mystery shopping project – is an opportunity, not a punishment

With the high competition rate between different supermarkets and grocery stores, being one step ahead is not an advantage, but a necessity. Market leaders need to be sure that all service standards are being met day by day, though it may be quite hard to gather all relevant information. 

Considering the balance between the service level of each store in the supermarket chain, it’s vital to determine different areas which need improvement. It would be advantageous to have someone to provide you with the full picture. 

That is where mystery shoppers can be very useful to supermarkets, as they help not only by reporting on the current situation but also by shedding some light on some service areas which need development in order to increase customer satisfaction. 

A mystery shopper is a real customer who provides structured feedback. It works well for those store directors who are interested in a real picture of the service received and are ready to take concrete actions.
