What Are the Primary Methodologies for Information Architecture?

i love to have you speak a little bit about just what are the primary methods that you as an information architect really lean on. So i feel like information architecture, because it is so related a to design in technology, especially in the company that i'm in,. We tend to use the same research methodologies for likhe testing the product itself, including the information architecture. And then ending with something a little bit more structured, whether that be a card sort or a full usability cycle.
