That's a great question! A task analysis is actually more systematic than just listing steps - it's about breaking down each user action into its smallest components to understand the actual process, cognitive load, and potential pain points. What really helped me was this practical guide that explains exactly what is a task analysis and how to conduct one effectively. It walks through different methodologies with real examples, showing how to document not just what users do but why they do it and where they struggle. The examples of hierarchical task analysis were particularly useful for visualizing complex workflows. I've been using this approach ever since and it's dramatically improved how I identify usability issues before we even start designing.
