# Policy Interpolation

## What it does
Interpolation lets you put dynamic variables in your configurations and policies. You write a policy once with placeholders, and the platform fills in the right value for each device or user at deployment time. No more maintaining dozens of near-identical policies or tracking custom values in a spreadsheet.

## How it works
Instead of hardcoding values per device, you configure once with variables:

```
Device Name: {{department}}-Laptop-{{device.serial_short}}
Email: {{user.email}}
Department: {{user.department}}
```

The platform substitutes the correct values for each device and user during deployment.

## Available variables
- User attributes: name, email, department, employee ID, location
- Device properties: serial number, model, OS version, enrollment date
- Custom fields: any custom attributes defined in your organization
- Organizational data: team names, cost centers, office locations

## Common uses
- Consistent device naming across the fleet
- User-specific email and app configuration
- Department-specific network profiles
