# Sub Graph

> Packages a group of steps into a single reusable unit inside a workflow.

The Sub Graph node bundles a group of steps into one tidy box on the canvas. The
steps inside run as a unit and hand their final result back to the main
workflow. It keeps a busy workflow readable and groups related work that belongs
together.

## When to use it

* Your workflow is getting crowded and you want to tuck a related set of steps
  into one collapsible unit.
* You have a self-contained piece of logic, like scoring an application, that you
  want to keep separate and easy to follow.
* You want a group of steps to produce one clean result the rest of the workflow
  can read.

## Inputs

| Field       | What it's for                                                     | Example                                      |
| ----------- | ----------------------------------------------------------------- | -------------------------------------------- |
| Description | A short note on what this group of steps does.                    | "Score and classify an application."         |
| Steps       | The steps that run inside the unit, with their own start and end. | Score the applicant, then classify the score |

The steps inside can read values from the main workflow, and the group's final
result becomes available to the steps that come after it.

## Outputs

| Field  | What you get back                                                           |
| ------ | --------------------------------------------------------------------------- |
| Result | Whatever the last step inside the group produced, available to later steps. |

## Example

An agency reuses the same application-scoring logic in more than one place. Those
steps, scoring the applicant and classifying the score, live inside a Sub Graph
named "Score and classify an application." On the canvas it reads as a single
box; the main workflow reads its result and routes accordingly. Grouping the work
keeps the top-level flow easy to follow.
