A Thai bank needed to know how its branch staff sell when no manager is watching. Its sales standards set out how staff should assess a customer’s needs, which products to recommend, and what to disclose about product features and risks before a sale. Head office could set these standards, but could not see whether they were followed at the counter, branch by branch.
For a bank, the gap between standard and practice is a compliance risk as well as a sales problem. Thai regulators expect banks to understand a customer’s needs and explain product risks before selling, so a recommendation made without a needs assessment, or a sale made without a clear risk disclosure, exposes the bank, not only the staff member. The bank wanted an independent measure, repeated over time, that would show where each branch stood.
Iconic Research ran a mystery shopping programme across 41 branches in each assessment round, in Bangkok and major cities across Thailand.
Each round gave the bank a branch-by-branch view of sales quality and compliance, scored against its own standards rather than general service measures. Because the criteria stayed constant across rounds, the bank could track whether branches improved from one round to the next and direct training and follow-up to the branches and sales steps that fell short.
Mystery shopping measures what happens in the conversation, not what staff report afterwards. For a regulated product sale, that is the difference between knowing the standard exists and knowing it is applied.
