Franz Hetz

CEO & Principal Test Manager

For more than ten years I have made sure that software keeps its promises: accessible and reliable. As a former Head of QA, I combine test management with hands-on testing, from WCAG and BFSG audits to SAP acceptance tests.

What I do

I test software where defects are expensive: legally, financially and for your reputation. My clients are banks, public authorities and software vendors whose applications must be secure and usable for everyone.

Accessibility testing: Since June 2025, the German Accessibility Strengthening Act (BFSG) applies to many digital products and services. I audit web applications, portals and PDF documents against WCAG 2.2, BITV 2.0 and EN 301 549, using screen readers such as JAWS and checking PDFs against PDF/UA.

AI in the testing process: I work extensively with generative AI and use it deliberately to make testing faster and more thorough. My A4Q AI Foundation and AI Essentials certifications give me the methodological basis to test AI systems themselves.

SAP testing: Acceptance and regression testing for SAP S/4HANA, SAP Fiori and SAP GUI, automated with Tricentis Tosca.

Test management and test automation: Test strategy, test planning, acceptance and maintainable automation with Selenium, Cypress, Playwright or Robot Framework.

Selected projects

Online banking platform of a large financial IT service provider (since 2024): Accessibility testing under WCAG and BFSG across at least two releases per year. Result: go-live with no remaining accessibility defects in production.
SAP HR portal of a federal authority (2025–2026): Around 100 accessibility defects found, documented and reported to SAP for fixing.
SAP S/4HANA Finance in the public sector (2026): Acceptance testing and step-by-step automation of the workflows with Tricentis Tosca.
Head of QA (2019–2024): Led a QA team of seven across two to three parallel projects with a three-week release cycle. The point-of-sale test suite is 100% automated; acceptance effort per release dropped from five person-days to one.
White-label car-sharing platform (2015–2018): Quality assurance for the web and mobile applications of a car-sharing solution.

How I work

I test myself instead of only coordinating. That way I know the application as well as the developers do and can assess risks realistically.

I document every finding so it can be fixed right away: location, violated criterion, severity and a suggested fix. For larger projects I work with a network of specialised freelancers.
