What sets us apart

Quality is not a feature. It is a decision.

Quality Consulting Taeschner /kjuː/siː/tiː/

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.

The person behind QCT

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.
