Become a trusted voice for quality,
not just the person who finds bugs

 Get notified when the next live cohort of Q.E.D. Mastery opens.
A 6-week, online training for testers who want to lead with evidence, not opinions.

In this course, you’ll learn to:

  • Reframe quality issues as business risks

  • Build metrics that change conversations

  • Run small, fast experiments that prove your impact

Become the person stakeholders ask for when they want to improve quality

I was pleasantly surprised at how interactive every session was. I have come away with real life examples from my current workplace, that I can now measure and communicate effectively. The focus on small short experiment cycles will really help us gather more information and hopefully untangle our problems quickly. I really recommend Katja's approach and the format of these sessions.
