The Problem

Business customers couldn't find answers without calling — and calls were expensive.

TSB's business banking customers faced complex, high-stakes queries — account management, payment queries, fraud concerns — that the existing digital support couldn't handle. Call volumes were high, and the chatbot that existed gave generic responses that eroded trust.

What I Did

Research & intent mapping

Analysed call transcripts and chat logs to identify the top business banking intents. Ran workshops with frontline agents to understand the nuance behind each query — what customers actually meant vs. what they said.

Conversation & flow design

Designed end-to-end conversation flows in IBM Watson Assistant — from opening intents through to resolution or warm handoff. Wrote dialogue that balanced confidence with appropriate caution for financial queries.

Support Journey

Mapping friction to rebuild confidence.

I mapped the end-to-end support journey from issue to resolution — capturing what customers did, thought, and felt at each stage — to find where effort, uncertainty, and drop-off occurred, and where conversation design could rebuild confidence.

Wireframes

Shaping conversation flows with wireframes.

I translated the conversation flows into high-fidelity wireframes in Adobe XD to test interaction patterns and pressure-test the visual design — focusing on structure, key decision moments, content hierarchy, and how customers move through different support journeys.

I explored ways to present information and capture input — prompts, quick replies, confirmation screens, escalation paths, and error recovery. The goal was natural, intuitive conversations with low effort for common banking tasks.

I reviewed the wireframes with stakeholders, product owners, and technical teams to validate requirements and improve the experience. Over several iterations, I simplified decision points, removed unnecessary steps, and clarified prompts and guidance — giving us alignment across business, user, and technical needs, and a clear blueprint that reduced rework in the build phase.
