How a Tier 1 bank found the real cause of a 19-point NPS crash in minutes
In this case study, you’ll see how a Tier 1 bank with a global footprint used Ipiphany to understand a sharp NPS drop in its online banking channel.
You’ll learn how the insights team:
- Analysed thousands of NPS comments in a single view instead of sampling
- Used topic tracking to see which themes drove the score down
- Isolated a browser-specific issue that customers were still experiencing
- Turned unstructured feedback into a clear story for leadership
