This document outlines Hansa Research's proposed methodology for conducting a benchmarking study of ING Vysya Bank's customer satisfaction levels compared to its major competitors. The study would measure turnaround times and customer satisfaction for key services like opening accounts, processing loans, and handling complaints. Hansa Research would conduct face-to-face interviews in multiple cities across India with ING and competitor bank customers who have used the target services in the last 6 months. The interviews would assess overall satisfaction levels and ratings across important service dimensions to identify strengths and weaknesses. Hansa Research would provide a detailed report analyzing the findings to help ING identify areas for improving customer service and satisfaction.
