How we used Feedback Analysis to find key areas that impact CX for our Insurance client

Our client is a leading insurance provider in the country. They were routinely collecting customer feedback through NPS® surveys. However, they were unable to perform feedback analysis of unstructured comments. This is problematic since the NPS® score is merely a number. Feedback comments are more crucial since they provide the reasons behind customers’ ratings.  


Mainly, Numr faced 3 challenges. These were-

  1. Perform Feedback Analysis of customer comments from the past 2 years to obtain insights about WHY customers have provided a specific rating.

(Say, if a customer has given an 8 on the NPS® scale, our challenge was to explain the reason WHY)

   2. To extract KEY DRIVERS/ AREAS that have the highest impact on customer satisfaction (recommendation)

   3. To establish a relationship between the NPS® score and feedback comments.  

The Numr Solution

We analysed around 3000 comments using our Comment Categorisation Formula to arrive at extremely precise conclusions. Our process was as follows.  


To run feedback analysis, we created several levels of drill downs.

LEVEL 1– was the overall, broad comment category. Basically, we categorised/ separated all comments into either POSITIVE or NEGATIVE.

LEVEL 2– represents sub-categories/ areas, such as, ‘Customer Care’, ‘Policy Features’ et cetera.  

See the chart below to understand how we create several drill down levels for comment analysis.

We used Text Analytics to automatically classify all comments into appropriate sub-categories.  

Then, we used Regression Analysis to isolate the impact (in terms of a β-value) an issue/sub-category will have on the overall NPS score.

For instance, see the POSITIVE COMMENTS chart below

Insurance Feedback Analysis NPS® Survey

We identified 9 main areas/sub-categories.

Now, each bubble represents one of the categories mentioned above.  

The X-axis represents the % of Promoters (customers who gave a rating of 9 or 10 on the NPS scale)

The Y-axis represents the IMPACT the sub-category has on the NPS score

And, the size of the bubbles represents the volume of comments under that category.


To simplify,  

We asked our client to prioritise areas with the highest X-axis and Y-axis value.  

FINDING 1- ‘Customer Care’ and ‘Customer Experience’ have the highest positive impact on Customer Experience. (We have circled them on the Chart)

Similarly, for the NEGATIVE COMMENTS CATEGORY, we followed the same process and discovered that

FINDING 2- ‘Follow ups and Communication’ and ‘Documentation’ were making customers the angriest. Since they had the highest negative impact on Recommendation, we advised our client to prioritise them.

What’s more, we broke down larger categories (volume of comments) into sub-categories for a granular and precise analysis.  

For instance, we further broke down ‘Time taken for Approval’ into ‘Initial Approval’ and ‘Final Approval’ to discover the EXACT source of the problem.

See the chart below for details.

Our analysis allowed our client to obtain granular insights that were infinitely actionable in a very short period of time.

With Numr’s help they were able to accurately pin-point specific issues and prioritise KEY AREAS that were having the maximum impact on customer satisfaction.  

Which, in turn allowed our client to serve their customers better and finally, boost Profits.  

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
