Rule

Business

A specific mathematical or logical expression which can be evaluated to determine specific behavior.

Rules are of several types: they may be derived from methods to determine the control flow of a process when it is being designed and executed; they may be used as the input parameters of processes (e.g. imputation rules, edit rules); and they may be used to drive the logical flow of a questionnaire. There are many forms of Rules and their purpose, character and expression can vary greatly.
