# How ORCA works

> The five building blocks and the conversion lifecycle

ORCA is organized around five building blocks. You set them up roughly in this order, and everything downstream depends on the ones before it.

## The conversion lifecycle

A real conversion isn't one load — it's a series of cycles that get faster and cleaner as they move toward go-live. You start with a POC on a test pod (`cycle-0`), work the errors until it's clean, then promote cycle by cycle toward the production cutover — each one faster because ORCA carries your mappings and learnings forward.
