NUCIDA | Transforming Software Quality at DAT Group

TRANSFORMING SOFTWARE QUALITY AT DAT GROUP

In the fast-evolving automotive industry, where precision, reliability, and innovation are paramount, the hidden champion DAT Group stands as a trusted neutral pillar. Founded in 1931 and headquartered in Germany, DAT has been empowering car dealerships, repair workshops, insurance providers, and fleet managers with data-driven solutions for fair vehicle valuations, accurate repair cost calculations, and seamless claims management. At the heart of their offerings is the SilverDAT®, a powerful digital platform that streamlines damage assessments, claims processing, and AI-enhanced workflows, ensuring efficiency in an era of sustainable mobility and electric vehicles.

HOW DOES NUCIDA HELP DAT GROUP?

Yet, even industry leaders face challenges in maintaining impeccable software quality amid rapid development and complex integrations. In 2019, DAT embarked on a transformative quality assurance (QA) initiative for their myClaim product line, partnering with QA expert and principal consultant Torsten Zimmermann to build a robust, future-proof testing ecosystem based on Xray, the test management solution for Jira, with integration of several test automation tools. As DAT expanded innovations like AI-driven damage detection and telematics integrations, ensuring flawless software performance became critical. Traditional testing processes struggled to keep pace, risking delays, defects, and suboptimal user experiences for clients in the automotive and insurance sectors.

BUILDING A WORLD-CLASS QUALITY ASSURANCE WITH XRAY

Torsten Zimmermann, Principal NUCIDA Group, led the establishment of dedicated QA teams, test processes, and test infrastructure. Central to this was the implementation of Xray as the core test management tool within Jira, seamlessly integrated via REST API with the KDT automation framework that controls test drivers such as AskUI, Browserstack, Selenium, and SoapUI. In addition, Jens Nietzschmann, CEO DAT Group:

"Our product family, SilverDAT®, not only offers top-of-the-line tools for vehicle identification, calculation of repair work and damage assessment as well as claims-related communication with insurance companies, but it also allows users to receive reliable used-car valuations or residual values through our large database and methodology. We are dedicated to providing the industry with the most superior products and services to make business easier and more efficient for our customers and clients."

This results in professional software quality management for the SilverDAT® Solutions that embraces both shift-left and shift-right testing. By extending beyond the core development process, it creates a continuous feedback loop connecting customers, end-users, and development teams, ultimately delivering world-class software tailored to the demands of the modern automotive service and insurance sectors.

BEST QUALITY AND MARKET LEADER POSITION

These enhancements have delivered sustainable improvements in product quality, optimizing development cycles and reducing risks. DAT's market position in the automotive and insurance sectors has strengthened, paving the way toward undisputed leadership. Rainer Ehrhardt, Product Line Manager at DAT Group, reflects on the transformation:

"Mr. Torsten Zimmermann and his consulting team advise us on establishing and further developing our quality assurance within the SilverDAT® product line. With his wealth of experience, he confidently introduced critical topics like test management, automation, and error tracking. Within six months, he achieved a significant improvement in software quality by increasing test coverage sixfold and halving test iteration times. His expertise motivated and enabled our team to work independently. Without his support, we could not have established such a sound and sustainable quality management system in that short period of time."

This partnership exemplifies how targeted expertise and tools like Xray can drive extraordinary outcomes: turning quality assurance into a competitive advantage. For DAT Group, it's not just about better software; it's about powering a more transparent, efficient, and innovative automotive future.

Nikolai Back, Pickert & Partner | www.pickert.gmbh

We at BMW Group rely heavily on enterprise-ready, robust and mature software. After evaluating some competitors over a longer time we finally decided for Xray. This high-quality software supports agile development processes very well, integrates smoothly into Jira and proves to be the missing part for testing in Jira in any aspect.

Michael Merwald, BMW | www.bmw.com

NUCIDA brought our engineers back to using a centralized tool for their test execution and specification. Xray has a very simple UI and a great API, so folks need only a couple of minutes to get used to it, without any training necessary. The team always has an open ear for feature requests and a quick reaction on bug fixes.

Florian Rohde, Tesla | www.tesla.com

The support service so heart-warming it almost melts you. Seriously, the questions I addressed were pretty hardcore but every item was resolved with a very detailed answer. After some ideas of mine, even an improvement report was created - looking forward to working with you guys.
