When training sales associates, the best measurement tool is VIDEO Mystery Shopping. Some sales associates are intimidated by the process, but when used properly, it is the best available training tool on the market.

Think of it as an investment in your sales associates to help them learn more and earn more. This approach can shed a positive light on shops.
