This article presents a 12-step usability testing process illustrated in comic strips across three different product designs: an app, a grocery site, and a toaster. Each comic uses distinct styles to engage readers while conveying the same core steps in user testing. The author also addresses character consistency issues in the comics and shares insights on the process.

The article argues against testing multiple design options at the same time, explaining that it often leads to unclear results and requires more participants. It emphasizes the importance of focusing on one design, learning from it, and making necessary improvements.
