Usability Testing and Iteration Questions

Covers the end to end practices for evaluating and improving the usability of products and documentation through iterative user research. Topics include designing task based usability tests, defining success metrics (for example task success rate, time on task, error rate, satisfaction scores), recruiting representative participants, writing moderated and unmoderated test scripts, running in person and remote sessions, and synthesizing qualitative and quantitative findings. Also covers split testing and variant experiments, analytics and event tracking to validate behavioral changes, collecting and prioritizing feedback loops from support and field teams, and planning iterative content or product updates. Candidates should be able to explain examples of test design, participant screening criteria, moderation approach, findings synthesis, decision criteria for changes, how they balanced user feedback with business constraints, and how they measured post release impact. For documentation specific testing, include approaches to measure task completion using docs, A versus B documentation variations, documentation search and discoverability metrics, and examples of content revision driven by user observation and usage data.
