Key takeaways

  • • 45% of back-office process steps added no value to the customer.
  • • More than half of all wait time came from branches not supplying the required data.
  • • Collecting the right data up front and inspecting early were the keys to recovering $1.5MM.

The challenge

Back-office operations are the most overlooked part of a financial institution. Invisible to customers, they deliver value through the speed and accuracy of every transaction, and they are often riddled with inefficiency, operational risk and inconsistent service.

A bank with an aggressive growth strategy asked ProcessArc to assess whether its processes could scale profitably, starting with account opening.

Our approach

We selected a high-volume and a low-volume branch, and at each a seasoned and a newer representative. Every account type was process-mapped from the branch request to completion in the back office, identifying operational risk points, inefficiencies and cycle times.

What we found

Across more than 50 processes:

  • 25% of steps were inspection points propping up ineffective processes
  • 45% of steps added no value: rework, waiting and follow-up
  • Over 50% of wait time came from branches not supplying the required data
  • Customer service agents spent 50% of their time entering data into screens
  • 40% excess capacity at some branches while others were bottlenecked
  • 28 back-office reports to verify 60 data points, and no performance metrics

The path to $1.5MM

  1. Define all required information and collect it as early as possible
  2. Move quality inspections to the start, so defective transactions don't travel
  3. Eliminate non-value-add steps at the root cause
  4. Use the existing IT infrastructure to support the refined workflow
