Problem

Retail service employees needed to consult internal rules and operating manuals while responding to customers. Finding and checking those documents took time.

Approach

The bank introduced a companywide generative AI system focused on internal-document search and summarization. Initial use centered on retail customer interactions, with access also available for other internal inquiries.

Takeaway
