Problem

Partner-center operators answered large volumes of questions from bank branches and postal savings counters. Complex products and extensive FAQ material made quick, consistent answers difficult.

Approach

Japan Post Bank introduced Fujitsu's AI knowledge assistant in August 2021. It transcribed calls and let operators search FAQ candidates using conversation text. Know-Flow DX subsequently made the accumulated FAQ accessible directly to counter staff, expanding nationwide in May 2022.

Results

~24,000post offices where Know-Flow DX use began on May 30, 2022, per FujitsuVendor case study[1]

Takeaway

The deployment connected operator-assisted retrieval with direct staff access to the same knowledge. Reductions in handling time and inquiry volume remained expected benefits.
