The Three Root Causes Behind Most Performance Failures
Slow systems cost real money before they ever crash. A 70% CPU threshold triggers automated alerts, isolates the root cause, and keeps users from ever seeing a 404.
End-to-End Testing: How to Stop the Maintenance Trap
Flaky end-to-end tests and 40% of time lost to maintenance: one HTML attribute added in 2017 still prevents this today.
What Bacteria Do Better Than Your Scrum Team

Testing thermal management in e-cars
200 system states and a virtual control unit replace the physical test cabinet in e-cars. Thermal management tests get earlier and sharper.
Year-End Review: AI and Accessibility
AI won't replace testers, but it will reward those who use it well. Here's where the real productivity gains are in 2026.
Performance Testing is not Load Testing
Performance testing is not the same as load testing, and running capacity tests every sprint is wasting cloud budget on the wrong problem.
Wind and weather - the challenges of testing wind turbines
164 subsystems, national lightning protection rules and offshore turbines without access. Testing wind turbine software is harder than it looks.
Accessibility testing of PDFs
PDF accessibility doesn't just apply to websites: Why contracts, invoices and policies must now be accessible and what this means in technical terms.
Using open source securely
Anyone installing open source needs a bill of materials, since it makes up 80 to 95 percent of software. Licenses, gaps and the Cyber Resilience Act.
Testing accessibility with those affected
Accessibility does not work automatically just because components are accessible. What goes wrong when assembling and why manual testing remains.
Cyber Resilience Act (CRA)
Mechanical engineers and the Cyber Resilience Act: What companies can expect, where the real hurdles lie and why early action brings a concrete cost advantage.
How AI can support accessibility
Accessibility tests today end up in a jumble of Word, Excel and browser tabs. How an integrated test environment can change this and how AI can help.
Accessibility - preparing for 2025
From July 2025, penalties of up to 100,000 euros apply for missing accessibility. What that means for design, development and for testing.
Accessibility testing
Accessibility in mobile testing: Why assistance systems hinder each other and which test matrix helps.
Accessibility
57 percent of accessibility criteria can be tested automatically - the rest requires human judgment and the right process.
Evolutionary quality
Demanding maintainability early while the market is still missing is wrongly prioritized. The evolution model shows which quality goals count.
C++ Quality by Design
C++ is 45 years old and yet deeply rooted in autonomous driving, medical devices and AI libraries. What the Core Guidelines have to do with it.
When customers are colleagues
