However, open-source communities still need standardized processes to ensure software quality, and their characteristics make it challenging to adopt many usability techniques from human–computer interaction directly. Our study aims to adapt and evaluate the feasibility of three usability evaluation techniques—cognitive walkthrough, formal usability testing, and thinking aloud—across three open-source projects (CodeopenAccessCOGNITIVE WALKTHROUGHFORMAL USABILITY TESTINGOPEN-SOURCE SOFTWARETHINKING ALOUDUSABILITY TECHNIQUESArtículo https://doi.org/10.3390/informatics12010012
