How to make customer feedback more useful with generative AI

Ruukki Construction Oy is a leading Finnish manufacturer of steel-based construction products as well as a service provider. Ruukki conducts a yearly net promoter score (NPS) survey in 10 countries where they receive a lot of open feedback in numerous languages. Ruukki turned to Vincit to find a way to use generative AI to quickly and easily summarize this feedback and present it in a more useful format. 


The challenge – open feedback in many languages

As part of the NPS survey, customers give feedback and improvement suggestions. Ruukki’s challenge has been to analyze and draw conclusions from this vast amount of data in different languages. It took hours of work from their research partner’s analysts to prepare summaries in previous years. This time around, Rukki wanted to test what modern AI tools could do with their feedback data.


This AI-supported analysis provided us with an amazingly accurate overall view of our customer sentiment. And more importantly, the summary and the recommendations help us to choose the areas that need improvement. That’s what really matters – to understand our customers’ needs and offer the best customer experience.

The solution – using generative AI

The task given to the Vincit team was to use generative AI to translate the data into English and get answers to three questions: 

  • what are Ruukki’s top 3 strengths?
  • what are the top 3 topics that customers refer to as improvement areas?
  • what are the possible recommendations for improvement actions?

In addition, the data needed to be handled in a safe and secure manner using Azure OpenAI API in an isolated environment where no third party could access the information. 

Vincit performed the work during a 2-week hackathon as a proof of concept to show how generative AI can accurately and usefully translate and summarize a large amount of information.
