Mortgage Processing Error Register

Mortgage Error Register and Root Cause Analysis Tool

Client

Retail Bank - Mortgage Acquisition Division

Business Problem

The mortgage acquisition operations team was facing recurring application processing errors that led to service delays, rework, and customer complaints, often resulting in breaching their client Service Level Agreement. 

Despite efforts to reduce issues, the team lacked a structured way to capture error data and identify systemic failure points. Without a clear view of root causes, operational costs remained high and process improvement stalled.

Solution Delivered

We delivered a lightweight but powerful Excel Add-in that empowered frontline processors to instantly capture error instances at the point of occurrence.

Data was stored centrally in an MS Access database, enabling consistent, structured recording of error types, causes, and downstream impact.

Key features included:

  • One-click error submission with pre-defined dropdowns to ensure classification consistency
  • A central reporting dashboard showing Pareto (80/20) distributions of error types, root causes, and impact metrics. As you might expect, 80% of the errors originated from 20% of the sources.
  • A built-in feedback loop for operations leadership to triage recurring issues and deploy fixes.

This solution created a closed-loop between error capture, insight generation, and process remediation—without disrupting day-to-day operations.

Results

  • Reduced average case processing time by 25% through targeted workflow improvements
  • Identified 3 recurring root causes responsible for over 80% of error-related rework
  • Improved first-pass processing rates, enhancing customer satisfaction and meeting SLAs
  • Enabled operations leadership to justify procedural changes with data-backed insights
