User Research - Part I

CS408 Human Computer Interaction Lecture 19 establishes the foundations of qualitative user research, providing Virtual University students with essential methodologies for uncovering genuine user needs, workflows, and motivations. While quantitative research reveals statistical trends and numerical metrics, qualitative research illuminates why users behave the way they do, bridging the gap between computational systems and human behavior. Grounded in the classical user-centered design principles formulated by Gould and Lewis in 1985—early focus on users and tasks, empirical measurement, and iterative design—qualitative research ensures software engineering lifecycles remain anchored in real-world human activities. The lecture examines five primary qualitative research techniques: stakeholder interviews, Subject Matter Expert (SME) interviews, customer interviews, user interviews, and contextual user observation. Stakeholder interviews allow design teams to uncover vital business goals, financial expectations, technical limitations, schedule constraints, and brand vision. Designers must interview key executives individually to capture unfiltered insights and establish organizational alignment. In parallel, consulting Subject Matter Experts provides critical domain knowledge, industry regulations, and operational terminology necessary for specialized fields like healthcare, finance, or engineering. However, interaction designers must exercise caution, as SMEs possess skewed perspectives: they are typically expert power users accustomed to awkward historical interfaces, leaning toward complex expert controls rather than the intuitive interfaces needed by perpetual intermediates. Furthermore, SMEs understand domain rules but lack interaction design expertise. The curriculum draws a sharp distinction between customers and actual users. Customers make purchasing decisions—such as corporate IT directors or parents—and focus on licensing costs, management oversight, and installation ease. In contrast, end-users directly interact with software to achieve daily goals. Effective design prioritizes user needs over customer preferences, as product adoption hinges on user satisfaction. Additionally, the lecture highlights user observation in authentic work settings, noting that individuals cannot accurately report their subconscious habits or cognitive workarounds outside their natural environment. Complementing field observations with literature reviews, customer support logs, and competitive heuristic audits enables designers to evaluate the existing technological landscape. For students preparing for CS408 midterm examinations, solved past papers by Moaaz and Waqar Siddhu, and chapter-wise practice MCQs, mastering these qualitative research concepts is vital for academic excellence and professional interaction design practice.
