Formula properties
Introduction
Formula properties can be derived from numeric or date card properties. They allow you to create automatically computed values, reducing opportunities for inconsistency.
You can create an aggregate property based on a formula property
A simple example is calculating the end date of an iteration based on the start date and the length of the iteration in days. Here "Start Date" and "Iteration Length" are Iteration card properties.
The formula definition might look like:
"Start Date" + ("Iteration Length" - 1)
