# Holiday entitlement (DMN)

Entitlement calculations are exactly the sort of rule that lives in a policy document and gets applied inconsistently. A table fixes that.

---

## What this example shows

* Service length as a numeric range.
* A contract type input constraining which rules apply.
* An output in days, pro-rated in the annotation.

---

## Columns

| **Column**                | **Type and meaning**            |
| ------------------------- | ------------------------------- |
| Years of service (input)  | number: complete years          |
| Contract (input)          | string: permanent or fixed-term |
| Entitlement days (output) | number: annual entitlement      |

## The decision table

Hit policy: **U (Unique)**. Cells are FEEL expressions, so a range, a list or a negation is a legal value; a dash means the input is irrelevant to that rule.

| **Years** | **Contract** | **Days** | **Annotation**                      |
| --------- | ------------ | -------- | ----------------------------------- |
| < 1       | "permanent"  | 25       | Pro-rated from start date           |
| \[1..3)   | "permanent"  | 25       |                                     |
| \[3..5)   | "permanent"  | 27       |                                     |
| \[5..10)  | "permanent"  | 29       |                                     |
| \>= 10    | "permanent"  | 32       | Capped at 32                        |
| \-        | "fixed-term" | 25       | Always pro-rated by contract length |

## Making it your own

* Pro-rating belongs in a literal expression, not in this table. Keep the two separate.
* Add a part-time input if entitlement scales with hours.
* Note the statutory minimum somewhere; the table should never fall below it.
