The correct answer is C. T-shirt Sizing, matching the answer contained in the UX Designer study guide. T-shirt sizing is a relative estimation technique commonly used during Agile planning when a team needs an approximate understanding of the effort, complexity, or scope associated with backlog items. Instead of attempting premature precision with hours or exact implementation durations, items are classified into categories such as XS, S, M, L, or XL. These relative sizes allow team members to compare work items and identify those requiring significantly greater effort.
That makes the technique particularly appropriate to the wording “roughly estimate the work required.” At sprint-planning time, the UX Designer may participate with developers, product owners, and other stakeholders in sizing work based on design complexity, research requirements, dependencies, implementation considerations, and validation effort.
A Prioritization Matrix serves a different purpose: it evaluates items according to criteria such as value and effort to determine priority rather than simply estimating size. “Sprint Backlogging” is not the estimation method being tested; the sprint backlog represents selected work rather than a relative sizing technique.
Therefore, T-shirt sizing provides a lightweight, collaborative method for estimating work before more detailed planning occurs.
