Customer Feedback
Crowdtesters can do things that in-house testers cannot. Therefore, crowdtesting can be very beneficial as an additional measure to get positive confirmation of software quality and valuable feedback on usability, even after in-house testing has been completed.
Within a very short time, we had put together a team to test the new version of Aligned Elements, our requirements and test management software. The experience during the test project was so great that we immediately booked several passbrains testers for an ongoing engagement.
Above all, the broad coverage of different devices and operating system versions and the many valuable usability feedbacks have helped us a lot to ensure the quality of our new Android-based software. passbrains’ managed crowdtesting services have now become an integral part of our software quality assurance strategy.
passbrains has developed a perfect solution for our needs, taking into account all our requirements and adding value by covering real-life scenarios that we cannot achieve in our labs.
Working with passbrains has enabled us to increase the success of our products and services through the valuable contribution our customers have made through passbrains' digital experience and testing solutions and services.
Crowdtesting with passbrains has repeatedly proven to be an efficient way of increasing our product quality and gaining important insights into the expectations of current and potential customers. In this way, we maintain a high level of quality and thus customer satisfaction and loyalty. It is also very beneficial that we can involve them in the innovation process via the platform.
