Evidence relating to object-oriented software design: A survey

There is little empirical knowledge of the effectiveness of the object-oriented paradigm. To conduct a systematic review of the literature describing empirical studies of this paradigm. We undertook a Mapping Study of the literature. 138 papers have been identified and classified by topic, form of study involved, and source. The majority of empirical studies of OO (object oriented software) concentrate on metrics, relatively few consider effectiveness.
