Voice of the Customer (VoC): understanding, collecting and exploiting customer feedback
Today, understanding your customers is a strategic lever for any business. Yet many organisations collect data without actually using it to improve their performance. The Voice of the Customer (VoC) enables this feedback to be transformed into concrete decisions and value-added actions.
At Mallette, our experts in market research and customer analysis support companies in structuring this approach, better interpreting their data and identifying concrete levers for improvement.
When properly harnessed, the voice of the customer becomes a powerful engine for growth. Here's how to capture and analyse it to extract real business value.
What is the Voice of the Customer (VoC)?
The voice of the customer, often referred to as the Voice of Customer (VoC), refers to all the opinions, perceptions, expectations and experiences expressed by customers about a company, its products or its services.
The concept of VoC (Voice of Customer) brings together all the methods used to capture and analyse customer feedback. This information can come from a variety of sources, such as satisfaction surveys, online reviews, interactions with customer service or even comments on social networks.
The aim is to gather qualitative and quantitative data that provides a better understanding of how customers perceive a company and its offering. By analysing this information, organisations can identify what is working well, but also the irritants that are damaging the customer experience.
VoC is not just about measuring satisfaction. It also seeks to understand customer expectations, motivations and frustrations, in order to detect opportunities for improvement or innovation.
The difference between Voice of the Customer and customer satisfaction
It is important to distinguish between the voice of the customer and customer satisfaction. Satisfaction generally corresponds to a one-off measurement, often assessed through a survey or an indicator such as the Net Promoter Score (NPS).
VoC, on the other hand, is part of a more global and continuous approach that aims to actively listen to customers and integrate their feedback into the company's strategy.
Why implement a Voice of the Customer strategy?
Implementing a Voice of the Customer (VoC) strategy enables companies to better understand their customer base and gear their decisions to real market expectations.
Improving the customer experience
A Voice of the Customer strategy aims above all to improve the experience at every stage of the customer journey. By analysing feedback, the company can better understand expectations and adjust its products, services and interactions. It also enables irritants to be identified quickly and concrete improvements to be made to deliver a smoother, more satisfying experience.
Strengthening customer loyalty
A better understanding of customers' expectations helps to strengthen their loyalty over the long term. When customers see that their comments are genuinely taken into account, trust is built up and the relationship is strengthened. By integrating the voice of the customer, the company creates a lasting bond based on listening and continuous improvement.
Stimulating innovation and continuous improvement
The voice of the customer is a real source of innovation. Feedback helps to identify areas for improvement, new ideas or adjustments to the existing offering. It also helps to pinpoint internal inefficiencies, enabling processes to be optimised and overall performance to be improved.
What methods can be used to gather the voice of the customer?
To implement an effective Voice of the Customer (VoC) approach, you need structured methods for gathering feedback.
By combining several sources of information, organisations obtain a more complete view of the customer experience and can more easily identify areas for improvement.
1. Customer satisfaction surveys
Post-interaction surveys and questionnaires
Satisfaction surveys are one of the most common methods of collecting the voice of the customer. They enable information to be gathered directly from customers in order to measure their perception of a product, service or experience.
Measuring the perception of the customer experience
These surveys can take the form of surveys or questionnaires sent after an interaction with the company, such as a purchase, a service request or contact with customer service. In particular, they can be used to assess different aspects of the customer experience, such as service quality, ease of use or overall satisfaction.
Net Promoter Score (NPS)
Among the most commonly used indicators is the Net Promoter Score (NPS). This indicator measures the likelihood of a customer recommending a company to their friends and family. The NPS is often used to assess customer loyalty and identify the promoters and detractors of a brand.
2. Analysis of customer reviews
Online reviews and evaluation platforms
The opinions and comments left by customers represent a valuable source of information for understanding their perception.
Companies can analyse reviews published online, for example on evaluation platforms, review sites or company profiles. These comments provide a concrete overview of the customer experience.
Social networks and digital conversations
The social networks are also an important channel for capturing the voice of the customer. Posts, mentions and comments shared by users can reveal expectations, frustrations or positive experiences.
Direct feedback from customers
Finally, analysis of customer feedback received directly by the company, for example via customer service or contact forms, can identify more specific needs and concerns.
3. Interviews and focus groups
Some methods provide more in-depth and qualitative feedback. This is particularly true of one-to-one interviews with customers.
Individual interviews
The one-to-one interviews provide an opportunity to explore their motivations, expectations and experience with a product or service in more detail. These exchanges make it possible to identify or dig deeper into certain survey findings.
Discussion groups
Focus groups are another interesting approach. They bring together several customers to discuss a product, service or experience. These discussions make it possible to gather a variety of opinions and gain a better understanding of the perceptions of different customer segments.
4. Customer journey analysis
Finally, customer journey analysis is another important method of understanding the voice of the customer. This approach involves examining the interactions and behaviours of customers throughout their relationship with the company.
Behavioural data
Behavioural data, such as journeys on a website, interactions with an application or purchasing habits, provide a better understanding of how customers use products or services.
Customer interaction analysis
Analysis of interactions with the company, whether these involve communications with customer service, requests for information or purchases, can also reveal friction points or opportunities for improvement in the customer journey.
How do you analyse and exploit the voice of the customer?
Collecting VoC is a major first step, but the real value of this approach lies in the company's ability to analyse the data collected and transform it into concrete actions.
Analysis of customer data
The analysis of customer data is based on two complementary types of data.
Qualitative data (comments, opinions, interviews);
Quantitative data (surveys, KPIs, behaviours).
By combining the two, the company obtains a complete view of the customer experience and can better identify the levers for improvement.
Identifying trends and irritants
After analysing the data, you need to identify trends and the main irritants.
Detect recurring problems;
Segment customers (profile, behaviour, sector);
Prioritise actions according to impact.
This stage enables the company to understand what comes up most often and to adapt its actions accordingly. By segmenting the data, the company can refine its analysis and target the most important improvements for the customer experience and overall performance. Identifying trends also helps to highlight the differentiators and strengths on which to build in order to stand out from the crowd.
Turning results into concrete action
To be useful, the voice of the customer must be translated into concrete action.
Improving the customer experience.
Adjusting the offering and communication.
Optimising internal processes.
This feedback enables rapid improvements to be identified, both in the customer journey and in internal organisation. By transforming this feedback into action, the company gains in efficiency and service quality.
Case study: a manufacturing SME improves its profitability through VoC
A Quebec manufacturing company (50 employees) specialising in the manufacture of industrial equipment was facing a number of challenges:
Delivery times deemed too long;
Increasing customer dissatisfaction;
Decreasing retention rate.
Questions asked of customers
The company has put in place a simple VoC approach, with :
A post-delivery survey (NPS + open questions);
Targeted customer calls with strategic accounts;
Analysis of customer service complaints and requests.
Examples of questions asked:
Are you satisfied with the delivery times?
What was most frustrating about your experience?
What could be improved?
Would you recommend our company? Why or why not?
The analysis carried out
After compiling the data (qualitative and quantitative), three major findings emerge:
62% of customers mention a lack of visibility on deadlines.
Many customers perceive delays as a lack of organisation.
Internal teams do not have a clear view of the progress of orders.
Real problem identified: It's not just the delay that's the problem, but the lack of communication and follow-up.
Actions taken
Based on this data, the company has implemented a number of concrete actions:
Implementation of a order tracking dashboard (Power BI).
Automation of customer communications (confirmation + milestone tracking).
Standardisation of the production and delivery process.
Training internal teams on managing deadlines and priorities.
Before / after results
Indicateur | Avant | Après 6 mois |
NPS | 21 | 52 |
Complaint rate related to delays | High | -45 % |
Incoming calls for order tracking | Very high | -60 % |
Overall satisfaction | Average | High |
What you need to remember
This case study shows that the voice of the customer is not just used to measure satisfaction. Above all, it allows us to understand the real irritants, which are often different from what the company perceives internally.
In this case, the challenge was not just operational, but also communicational.
By acting on the right levers, the company improved both its customer experience and its internal efficiency.
Tools for managing the voice of the customer
Today, several technologies enable companies to implement a VoC strategy.
By combining different tools, organisations can gain a more complete view of the customer experience and improve their ability to act quickly on identified problems.
VoC platforms
The VoC platforms are specially designed to collect and analyse customer feedback on a large scale. They make it possible to centralise data from different sources, such as surveys, customer service interactions or online comments.
Feedback analysis tools
The feedback analysis tools enable customer comments and reviews to be examined in order to extract relevant information. Thanks to these solutions, companies can analyse large volumes of feedback from different sources, such as social networks, online reviews or satisfaction surveys.
CRM and CX tools
Customer Relationship Management (CRM) and customer experience management (CX) tools enable the centralisation of interactions between a company and its customers, whether they be service requests, purchases or communications with customer service. By bringing this information together in a single platform, companies can better track the customer journey and identify friction points in their customer relationships.
Customer data analysis solutions
Finally, customer data analysis solutions enable the information gathered to be exploited in greater depth. These tools offer advanced functionalities for analysing customer behaviour, identifying trends and measuring the impact of actions taken.
Give real strategic value to your customers' feedback
Understanding the voice of the customer enables companies to improve their customer experience, optimise their processes and make better decisions. However, for this approach to generate concrete results, it must be integrated into a structured strategy and supported by rigorous analysis.
