Quality is not a feature. It is a decision.
Our Q–CiTy stands for the complex, living software infrastructures that give people places to shop, to be served, to be entertained, to be distracted, or to relax — like a city. Built on a stable, reliable foundation: quality.
QCT is a specialised consulting network for software quality, test management, and AI compliance. We support organisations where quality becomes a strategic question: when adopting agile ways of working, building robust test strategies, preparing for the EU AI Act, or delivering demanding projects on the ground.
What we actually do for you.
Strategic consulting, hands-on projects, and team enablement. Bookable individually or as one continuous package.

A quarter century of high-quality work sits behind these numbers. We have accompanied more than 30 major projects across that time, from the first concept sketch to a stable rollout, with year-round commitment and the attention each phase deserves.
Our field of expertise.
The focus areas of our project practice. The methodical depth of testing and quality assurance carries beyond these domains, wherever software quality becomes decisive.

Generative AI, chatbots, autonomous agents. Test concepts for non-deterministic systems and compliance under the EU AI Act.

Christian Taeschner.
My mission is to support organisations in building digital products that meet the highest quality standards. Today I do that with hands-on advisory on test strategies and test processes, by leading test management mandates, and by coaching teams and leaders towards sustainable quality.
My depth comes from 25+ years across automotive, communications, and AI systems — at Siemens, Unify, SQS, and Expleo. With QCT, that experience is now available to your project without detours.

Often a fifteen-minute call already brings the first answers. You sketch the situation, I mirror back what stands out and what is worth checking based on my experience. If we fit, we keep going. If not, you still walk away with an assessment.
