# Value Stream Components Value streams are built from a few core building blocks: **triggers** start or resume a process, and **process steps** are the actions that run in sequence. You can refine when steps run using **conditions**, and repeat parts of the flow using **looping**. Understanding these components helps you design clear, reliable processes—so it’s worth getting familiar with each before you build your flows.
