When taxonomies are arranged hierarchically, it means that successive categories, ranks, grades, or interrelated levels are being used. In a hierarchy, a user would have to select a labeled grouping to find things within it. A hierarchy of movies might look like this:
Hierarchies tend to follow two patterns. First, a broad and shallow hierarchy gives the user more choices up front so they can get to everything in a few steps. As an example, in a grocery store, you choose an aisle, and each aisle has certain arrangement of products, but that's as deep as you can go.
Because your structure may change a hundred times before you finish making it, you can save time and frustration by thinking with boxes and arrows before making real changes. Boxes and arrows are easier to move around than the other materials we work with, so start there.
