Information Architecture Research: Testing Navigation at Scale with Sequence Flow¶
Testing Navigation and Menu Structures with Sequence Flow covers setting up a single navigation test. This guide is about the bigger picture: running information architecture research as an actual program across a full site or product structure, not just one menu in isolation.
Why One Test Rarely Answers the Whole Question¶
A real product's information architecture usually has multiple levels - top-level navigation, section groupings within a category, ordering within a specific flow. Testing only the top level and assuming the rest follows the same logic often misses real friction points buried deeper in the structure.
Structuring a Multi-Section Study¶
Build separate Sequence Flow sections for each distinct structural question you need answered - top-level navigation priority in one section, sub-category grouping in another, task-flow ordering in a third. Keep each section focused on one structural question rather than combining unrelated groupings into a single arrangement task, which tends to produce noisier, harder-to-interpret results.
Using Partial Arrangement for Large Item Sets¶
If a section of your site has more items than makes sense for a respondent to fully rank, use an Arrangement Range to ask for just the top handful rather than a forced ranking of everything (see How to Set Up a Sequence Flow Section (Full vs. Partial Ranking)) - this keeps the task manageable for respondents while still surfacing what matters most to them.
Reading Results Across Multiple Sections¶
Review each section's Route Flow and Route Network results independently (see Reading Sequence Flow Results: Consensus Routes vs. Averaged Rank) before trying to synthesize them into one overall structure - a clean consensus in one section and a genuinely split result in another tell you different things about how confident to be in each part of your eventual structure.
Testing With Different User Segments¶
If your product serves meaningfully different user types (new users versus power users, for instance), consider running separate waves per segment rather than assuming one navigation structure serves everyone the same way - compare with Combined Survey (see Cross-Tabs and Combined Survey Analysis in Reporting) to see where expectations diverge.
Turning Results Into a Decision¶
Since this kind of research rarely produces a single unambiguous answer, use it to narrow the reasonable options rather than expecting it to dictate a final structure outright - pair it with your own product judgment and any flagged uncertain transitions (see Reading Sequence Flow Results: Consensus Routes vs. Averaged Rank) as areas worth a second round of testing before committing.
FAQ¶
How many separate Sequence Flow sections is reasonable in one study?
This depends on respondent fatigue - a longer survey risks lower completion rates (see Completion Rate and Average Time: What Your Survey Management Page Shows You), so balance thoroughness against survey length.
Should I test the whole navigation structure or focus on the parts we're actually planning to change?
Focusing on the parts under active consideration is usually more efficient than re-testing structure you're not planning to touch, unless you specifically want a baseline for comparison later.
Can this replace card sorting?
See Sequence Flow vs. Card Sorting: Which Fits Your Research Question for how the two methods differ and when each is the better fit.
How do I decide between full and partial ranking for a large item set?
See How to Set Up a Sequence Flow Section (Full vs. Partial Ranking) for the trade-offs.
