Yann Person provides advice on how to start quality assurance (QA) for startups that typically have limited resources and no existing QA processes. The document recommends (1) building basic automated tests for critical features, (2) monitoring products by logging errors and checking patterns, and (3) working with developers to discuss quality and train them on QA tools. The goal is to establish an initial QA process that can be improved over time within the constraints of a startup.
