The bank of China customers can only deposit cheques offline, they wanted to move to digital solution.

As part of the digital transformation team, I led the user experience from user requirement to launch, by validating business logic and implementing the UX design.

The design was put into production and is now part of the corporate bank app's key offering.

Final Outcome

The Business Problem

Problem

  • Cheques can be deposit offline only
  • Time-consuming and leads to long queues at branches

Solution

  • Deposit cheques by taking a picture in the mobile app

Goal

  • Reduce branch handling costs
  • Increase mobile app usage

Logic

Validating Business Logic

Multiple Scenario-based Checkings

The process included checks like verifying cheque readability and account limits. The complexity increased when users deposited multiple cheques in different currencies at once. I validated business logic by:

  • Benchmarking
  • Visualizing Business & System Logic
  • Identifying and Resolving Gaps

In the end we successfully identified over 20 unhappy flows and collaborated with developers to make sure the logic is robost.

Benchmarking

We started by analyzing competitors’ workflows, but their systems only supported single cheques and currencies, offering limited insights for our more complex needs.

Visualizing Business & System Logic

After receiving the business logic from the team, I translated it into clear screenflows. I also mapped out the system integration, showing where data is saved and processed at each stage.

Identifying and Resolving Gaps

We found gaps and missing unhappy flows during the process, so I worked closely with the business team to clarify them, ensuring the user stories remained accurate and aligned.

Usability

Implementing UX Design

Error Handling Experience

Key part of the implementation is to help users understanding why their cheques couldn’t be deposited, especially in the case that there are multiple problems.

User Preference for Step-by-Step Error Resolution

We tested several solutions and found that users preferred resolving errors one by one, even if it required more steps, as it provided clarity and reduced confusion.

2 rounds of usability tests with 14 internal users.

Help user understand multiple errors

Our Usability tests revealed that displaying errors one by one is less overwhelming for users.

Resolve Errors One by One

Users are guided through each error individually, starting with acknowledging the issue and then choosing to retake or remove the problematic cheques.

Resolving scenario with duplicated cheques and error recognition issues.

Adaptablility

Handling Surprises

Quick Solutions Under Constraints

Months after the design was approved by both product managers and developers, we were informed that several elements couldn’t be implemented as designed due to time constraints. To overcome this, I pushed for:

  • Re-solutioning with developers
  • Prioritized key UI adjustments
  • In the end, we proposed actionable workarounds that preserved a solid user experience while meeting the deadline.

    Re-solutioning with developers

    We quickly organized an emergency meeting with devs to understand their limitations, proposing various alternatives to find feasible solutions.

    Prioritized key UI adjustments

    I created a guide categorizing issues by priority: high-priority usability fixes, like confusing icons, and lower-priority aesthetic tweaks, such as spacing.

    Final Outcomes

    The feature launched in early 2024, positioned as a key offering to attract small business owners to adopt the mobile app, streamlining their cheque deposit process and enhancing overall user convenience.
