parameter

System boundary factor

A parameter is a variable that defines the conditions or limits of a system or operation.

In mathematics and programming, parameters are values passed into functions that determine their behavior: The function takes two parameters: width and height.

More broadly, parameters are the boundaries within which something operates: We need to work within the parameters of the budget.

The word often appears in the plural to mean constraints or guidelines: What are the parameters of this project?
