Customer satisfaction is a vital factor and a goal that all banks are currently pursuing. Accordingly, banks and financial institutions need to conduct focused research and analysis on customer satisfaction during transactions, thereby making recommendations to enhance operational efficiency.
One of the most objective and accurate evaluation methods is to use mystery shoppers. This is a common method worldwide, helping banks gain a more realistic view of service quality through the actual experiences of customers.
This assessment is also known as “mystery customer research” or “detective customer research” in banking.
What is mystery shopper research in banking?
Mystery shoppers are a service evaluation program in which trained individuals pose as real customers to experience services at branches. The purpose is to assess service quality, employee attitude, operational procedures, and key touchpoints that impact the customer experience.
The mystery shopper program will be evaluated according to specific criteria and the evaluation method will be tailored based on the bank's requirements, criteria and regulations combined with the fundamental elements of a standard customer service.
In the role of regular customers, the trained team (Mystery Shoppers) will observe factors that affect overall customer satisfaction in the transaction room.
This program helps banks:
- Identify strengths and weaknesses in customer service.
- Propose measures to improve service quality.
- Ensure consistency in the customer experience.
Key touchpoints of the bank's secret customers
Main touch points at the bank include: Tellers, Transaction point facilities, Security.
At each touch point, Mystery Shoppers will observe and secretly record the entire journey as well as evaluate other subjects if they appear on the Mystery Shoppers' journey.
