Optionally, for any Assumption, you can add [**Sensitivities**](https://help.taglo.io/cases/managing-sensitivities) that will vary the value of the Assumption according to certain rules.

{% hint style="info" %}
This is an optional step of the Assumptions wizard, and you will be able to exit from the wizard before reaching this point
{% endhint %}

## Sensitivity type

You can choose from one of 3 sensitivity types:

<table><thead><tr><th width="231">Sensitivity type</th><th>Details</th><th>Example</th></tr></thead><tbody><tr><td><code>Percentage change</code></td><td>Varies from base value by a percentage</td><td>Base Value = 10<br>Sensitivity Value = +20%<br>Used Value = 12</td></tr><tr><td><code>Delta</code></td><td>Varies from base value by an absolute amount</td><td>Base Value = 10<br>Sensitivity Value = 2<br>Used Value = 12</td></tr><tr><td><code>Absolute</code></td><td>Replaces base value with an absolute amount</td><td>Base Value = 10<br>Sensitivity Value = 12<br>Used Value = 12</td></tr></tbody></table>

{% hint style="info" %}
Available Sensitivity Types will depend on [**Data Type**](https://help.taglo.io/data-types/data-types) of the Assumption. For instance, `Validation` and `String` Assumptions can only have `Absolute` sensitivities.
{% endhint %}

## Sensitivity value entry

Add any sensitivity values to the table displayed. You do not have to enter any values, as by default, no sensitivity is applied unless specified.
