USABILITY TESTING PROCESS EXPLAINED IN COMIC STRIPS

Summary from the TLDR Design newsletter

Jakob Nielsen created three comic strips using Nano Banana Pro to illustrate his systematic 12-step usability testing process, applying it to different product types: a plant care app, a grocery e-commerce site, and a toaster. Each strip uses a distinct visual style—from the default comic style to a realistic digital airbrush approach with character sheets, to a children's comic featuring animal characters. Nielsen recommends following all 12 steps for teams new to user research, though experienced teams may shorten some steps depending on their project.
