I will send you the beta reading link in an email too. Until then:
100 ways to flop a usability test.
Letters from the UXR Coach.
You are doing decent Usability Tests, but the product team doesn't seem to listen. They challenge your method, your sample size, your everything...
You may choose to ignore the warning signs. May even blame the team for its "lack of UX maturity". But deep down you know that if your service was truly transformational, they just couldn't get enough of it.
You do your best at doing UT the way you were taught, but you are starting to doubt yourself and feel like an impostor.
Maybe you have missed something essential. So you hurry to catch up with the latest around the web. But it's just an endless newsfeed parroting back commonplaces in a loop.
You may bury yourself in the classic books, hunting for the few practical gems among the vast body of fundamentals you already know. Who has that kind of time anyway? You are busy working.
A UXR coach could spot your gaps and show the techniques you lacked. It's just you have no such person available.
That is why I wrote "Letters from the UT coach".
During my many years as UXR and as a mentor I observed what mistakes practicing UXRs still make when Usability Testing.
Each of the 60+ letters is a bitesize take on an issue or technique: explaining why it matters and how it works by someone with experience in cognitive research as well as industry research. When necessary, I also debunk widely-shared misconceptions that usually come from the lack of understanding of the underlying psychology.
Each letter is a 1-minute read, a micro-skill that you can acquire then and there. And each is illustrated so we have something for your eyes too.
Once you ticked off each, I can confidently say that your UT is on par with that of any UXRs I have ever worked with.
Knowledge is the most effective antidote to impostor syndrome because if you understand how things work, you can confidently defend your practices and convert skeptics.
