HCI Requirements Engineering: Functional and Non-Functional Needs

Every successful digital product begins with a clear understanding of what it must do and how it must perform. Without well-defined requirements, even the most visually stunning designs can fail to meet user expectations. This course guides you through the foundational principles of Human-Computer Interaction (HCI) requirements engineering, helping you systematically identify, analyze, and document both functional and non-functional requirements to ensure your digital designs are user-centered, accessible, and technically viable. What you'll learn: Understand the fundamental differences between functional and non-functional requirements in product design; Identify user, data, and environmental needs through structured HCI methodologies; Define usability and accessibility requirements, integrating modern standards like WCAG into your specifications; Document performance, security, and privacy constraints as critical non-functional requirements; Translate user research into actionable specifications and clear acceptance criteria. You will start with core terminology and the lifecycle of requirement gathering before advancing to practical techniques for documenting and validating your design specifications. Through clear written explanations and structured analysis exercises, you will build a solid framework for user-centered design. This course is designed for aspiring product managers, UX/UI designers, and system analysts who are new to HCI, with no prior technical or design experience required.
