Though it sounds straightforward, that question uncovers something more profound. One may easily say you break things apart, you think, you witness. But there is a pause when someone asks precisely what.
Since observation is not all there is in analysis. They observe what is deliberately ignored as well as what is said.
Their reactions, their customs, their choices. Why they react a particular manner. Why they make particular errors repeatedly. Although often more unpleasant, that kind of investigation is quieter.
Are you trying to dominate or are you trying to comprehend? Are you seeking for simplicity or just overthinking everything until nothing seems easy any longer?
Analysis at its finest produces awareness. It assists you to see clearly, make superior choices, and bypass pointless errors. But it snares you when it passes too far. You start doubting every action, every idea, every result till doing becomes tough.
