Testing new products or services: a lever for a successful launch

In a small meeting room, a team carefully observes the reactions of a panel of customers to a product still in the prototype phase. The feedback is pouring in: a detail in the packaging, a poorly understood functionality, a word that doesn’t get across. Every comment is valuable. Testing new products or services before putting them on the market is no longer a simple luxury: it is now an important strategic investment.

According to Bpifrance Le Lab (2024), in France, around 73% of innovative companies attest that user tests were decisive in rectifying significant errors before marketing. This trend also affects young companies as well as well-established companies, all facing the difficulty of attracting consumers with high expectations.

Why testing a product or service is essential

Reduce risks before launch

Every launch carries risks. In France, according to an IFOP survey (2023), 60% of consumers have already abandoned a product after a disappointing first try. Testing a product upstream allows us to detect ergonomics, functionality or communication problems before the market judges the brand.

Companies that integrate testing early in the process reduce the risk of commercial failure by 30% (Bpifrance, 2024). It’s a concrete way to avoid costs linked to returns, corrections or ineffective marketing campaigns.

Understand the real needs of consumers

Testing also allows you to better understand user expectations. Studies show that 68% of French people are ready to share their opinion on a product if this helps to improve it (Kantar, 2024). This feedback provides direct insight into consumer barriers, motivations and preferences, thereby strengthening the relevance of the final product.

The most effective testing methods

User testing: observe to improve

User testing involves having real customers interact with the product or service and observing their reactions. Qualitative feedback – difficulties encountered, spontaneous comments, emotions – makes it possible to quickly identify weak points.

According to the Nielsen Norman Group (2023), a user test with only 5 to 10 participants can detect up to 85% of major problems. It’s a simple yet powerful method, applicable to almost any industry.

Prototypes and MVPs: test before investing

The concept of Minimum Viable Product (MVP) consists of launching a simplified version of a product to verify market interest. This approach, very widespread in French start-ups, makes it possible to limit initial investments while validating customer acceptance (Bpifrance, 2024).

The MVP is used to confirm design assumptions and quickly adjust the product before full deployment.

Consumer surveys and panels

Online surveys and panels make it possible to collect quantitative data on a large scale. They help test the relevance of a price, packaging, functionality or marketing message.

A recent IFOP study reveals that 42% of consumers say their responses directly influence the final product. This data allows companies to anticipate market expectations and reduce the risk of dissatisfaction.

Tests in real conditions

Some companies choose full-scale testing, launching the product to a limited number of customers in a real environment. This method makes it possible to measure the effectiveness and acceptance of the product in conditions close to the real market.

These tests often reveal issues that don’t show up in labs or simulations, such as navigating an online service or using a product on a daily basis.

The concrete benefits of testing for the company

Improve customer satisfaction

A product tested and adjusted according to user feedback better meets real needs, which increases satisfaction and reduces returns or complaints. A Kantar study (2023) shows that companies that test their products see an average improvement of 25% in customer satisfaction.

Reduce error costs

Identifying issues before launch avoids expenses related to post-launch fixes or recalls. According to Bpifrance, a well-conducted test can reduce costs linked to design errors or product returns by 20 to 30%.

Retain and engage customers

Involving consumers in testing strengthens their engagement and loyalty. Participating customers feel heard and are more likely to recommend the product and remain loyal to the brand.

Driving continuous innovation

Testing allows you to identify new ideas and avenues for improvement. User feedback often provides an unexpected perspective, promoting a cycle of innovation and continuous improvement.

Pitfalls to avoid when testing

  • Test too late : asking users only at the end of the design makes corrections costly.
  • Samples too limited : too small a panel can give a distorted view of real needs.
  • Ignoring Negative Feedback : reviews are often more useful than compliments in improving the product.
  • Not analyzing data : collecting opinions without drawing concrete conclusions reduces the impact of the test.

The culture of testing in France

The testing culture is growing strongly, especially in innovative sectors. According to Bpifrance (2024), nearly 70% of French start-ups integrate user tests or MVPs into their development strategy, compared to 45% of more traditional companies.

But the trend also extends to services, distribution and even certain public services, where testing allows us to better understand user needs before deploying a service on a large scale.

Test to succeed and innovate

  • Evaluating a product or service does not represent an expense, but rather a strategic investment.
  • It helps minimize risks, better understand customer needs, increase their satisfaction and encourage innovation.
  • The statistics confirm this: companies that carry out tests note:
  1. a 25% increase in customer satisfaction,
  2. a 20 to 30% reduction in error-related costs,
  3. strengthened customer engagement.
  • In an increasingly competitive environment, taking user feedback into account and adjusting your offering before launch is not only a preventive measure, but a real lever for success and differentiation.
