'''Feature interaction''' occurs when the presenceintegration of onetwo ''featurefeatures'' modifieswould somemodify the ''propertiesbehaviors'' of anotherone or both featurefeatures.

The term ''feature'' is used to denote an unit of functionality. Similar to many concepts in computer science, the term can be used at different levels of abstraction. For example, the plain old telephone service (POTS) is a telephony feature at one level, but itself is composed of originating features and terminating features. The originating features may in turn include the provide dial tone feature, digit collection feature and so on.

This definition of ''feature interaction'' allows one to focus on only certain propertiesbehavior of the interacting features such as how their response time may be changed upon integration. Many researchers in the field consider the problems that arise due to change in the execution ''behavior'' of interacting features. TheUnder that context, the ''behavior'' of a feature is defined by its execution flow and output for a given input.
