To build successful digital products, you must validate these assumptions early through structured usability testing. This text-only course guides you through the foundational principles of UX research, teaching you how to transform risky hypotheses into evidence-based design decisions. You will learn to plan, execute, and analyze user tests to ensure your product truly meets user needs. What you'll learn: Understand core UX research terminology and the psychology of user behavior; Formulate testable assumptions and design effective usability test plans; Conduct both moderated and modern remote unmoderated usability tests; Analyze qualitative user feedback to identify critical usability friction points; Apply ethical research practices and basic accessibility testing principles; Integrate continuous testing loops into agile product development cycles. You will begin with foundational UX concepts and the science of assumption-mapping, before progressing to step-by-step guides on drafting test scripts, observing users, and translating raw findings into actionable design improvements. This course is designed for beginner UX designers, product managers, and entrepreneurs with no prior research experience.
