OO metrics data gathering environment

Object technology has been recognized as an enabling factor and it is largely introduced into MIS departments. However, the benefits and improvements related to object technology are not obvious and could not be realized and achieved without appropriate evaluation criteria and metrics. The paper presents some evaluation criteria, measures and metrics, suitable for object oriented software development. Basic concepts of the OOMetDaGa Environment that provides automatic support for metrics data gathering are described and some empirical data presented.
