How to use parameter

Parameter is widely used in technical and business contexts to denote a measurable or controllable factor that defines the scope or behavior of a system. In technical usage, it refers to a variable in a mathematical formula or computer program; in general usage, it means a limit or guideline that governs what is acceptable or feasible. The term is more precise and less colloquial than limit or boundary.

A common mistake

Learners sometimes treat parameter as a synonym for 'problem' or 'issue' when they mean 'aspect' or 'factor'; parameter itself does not imply difficulty.
