Dear clients,

Thank you for visiting us!

Many long-time QDA customers already know me from my time at ASI DATAMYTE - from a variety of successful projects which we implemented together or as your technical contact for software changes along the QDA product line.
Over the past 15 years QDA virtually became my own back yard. Furthermore, I had the privilege to learn a lot about integrating QDA into very individual environments.

My impression is that the key to success has always been based on both competences – high level of product expertise and good knowledge of the target environment. Based on this principle our goal at QC-S is to keep providing you with the same high quality of services in the future.

If you have questions or actual needs please contact us.

I am looking forward to continued successful collaboration!

Jan Dunkelmann

The Company

QC-S was founded in 2014 by former QDA Product Manager Jan Dunkelmann. Our headquarter in Luebeck, Germany is not more than 5 km away from QDA's Global Headquarters and 10 km from the beautiful beaches of the Baltic Sea. Providing consultancy, software and services in the areas of Quality Management and Quality Assurance we are committed to both the partnership with our supported software vendors and close relationships with our clients. The company's orientation towards continuous growth is accompanied with our pledge to superior expertise.

The Concept

Product expertise and knowledge of target environment

The manifold tools of Quality Management Software packages (QMS) require comprehensive knowledge of the product. By the same token expertise in the target environment is essential to reasonable and successful use of those tools. QC-S is combining both competences.

Close ties to our clients

Continuous provision of quality does not end with the implementation of a software product. Instead, products, processes and technologies are subject to constant change - repeatedly causing new challenges and potential for improvement. As a reliable, competent and responsive partner QC-S is delivering economical and efficient solutions.


The 2019 Control Show in Stuttgart is getting close, and once again we offer you warm hospitality in our booth. From May 07 - 10, you will find us in Hall 5 / Booth 5600-1, close to our friends from QDA Solutions.

We are looking forward to sit down with you in a pleasant atmosphere to talk about current challenges and other topics, which everyday business meetings do not always leave time for. This year, John Fithian from our North America office will be attending.
