10.3.2.4 Churn through transformations

A Transformation calculates an effective Churn Proportion from the churn associated with each of its Inputs: for a Resource input, the weighted average of Churn Proportions of Services using that Resource.

There are two inputs which let you choose whether this effective churn is associated with the Output of the Transformation, depending on the modelling context.

Churn Resources

No: the capacity of Resources used by the Transformation is not churned.

Yes: the effective Churn Proportion is applied to the capacity of Resources used by the Transformation.

Pass On Churn

No: the Output of this Transformation has no associated churn when used as an Input to another Transformation.

Yes: the effective Churn Proportion of this Transformation is used in the calculation of the effective Churn Proportion for another Transformation which takes this Transformation as an Input.
