# Workflow Patterns (/workflows/workflow-patterns/overview)



Workflows orchestrate agents, teams, and functions through defined control-flow patterns. Each pattern covers a specific control flow, from sequential steps to branching, loops, and parallel execution, and patterns can be combined in the same workflow.

## Building Blocks [#building-blocks]

The core building blocks of Agno Workflows are:

| Component     | Purpose                         |
| ------------- | ------------------------------- |
| **Step**      | Basic execution unit            |
| **Agent**     | AI assistant with specific role |
| **Team**      | Coordinated group of agents     |
| **Function**  | Custom Python logic             |
| **Steps**     | Named sequential group          |
| **Parallel**  | Concurrent execution            |
| **Condition** | Conditional execution           |
| **Loop**      | Iterative execution             |
| **Router**    | Dynamic routing                 |
| **Workflow**  | Nested workflow                 |
