Leveraging Default Rules

Overview

 A Rule evaluates input data to determine whether the data matches certain conditions. Decisions offers many simple rules by default in the Flow Designer and the ability to create custom rules. Determining when to use custom rules depends on the complexity of the evaluation needed. 

Leveraging Default Rules

 Using default rules over custom ones is preferable for easier maintenance and visibility. Default rules typically take in Input Data and output a true or false path. If an evaluation calls for comparison against elementary data types, there is likely a simple Rule out of the box in Decisions. These default rules can be found by utilizing the Flow Designer's steps panel search function. 

There are situations where a custom Rule should be utilized. A custom Rule may be a better option if an evaluation calls for multiple and/or statements or checks multiple properties of a composite data type.
