The Feature Interaction Problem

Feature interaction occurs when one feature modifies or subverts the operation of another one. This phenomenon can occur in any software system that is subject to changes; it is becoming a major issue in software product lines.

The proliferation of players and software/service engineering techniques coupled with the constant pressure for the rapid introduction of new services and applications lead to undesirable interactions that jeopardize the quality of the products delivered as well as the satisfaction of the users.

Detecting, solving, preventing, and managing such interactions at different stages of the development process are more than ever important problems that need to be addressed with cost-effective techniques and tools.

Application Domain

The feature interaction problem was first studied in the domain of telecommunications systems. Although interactions among classical telephony features are now fairly well understood, the feature interaction problem presents new challenges in emerging types of systems, including

Techniques successfully applied to conventional telecommunications systems are still useful in many cases, yet they may no longer be able to cope with the complexity of the emerging systems.
