This paper is written for suggesting systematic object identification process which helps the analyst find out quality objects especially in the software having GUI. The process includes the procedure and the related heuristics both. The procedure is the sequence of the activities required for object identification, and the heuristics are the useful techniques for each activity. The critical milestone is employing the concept of responsibility as a system decomposition criteria. Respon-sibility is a set of inherent data, functions, and realtionships. The basic process is the decomposition based on the responsibility and sequential application of the related heuristics. The heuristics include object typing like macrostereotype, and microstereotype and their pattern, the generic system scenario which is made up of macrostereotypes, the idea on rule modeling, and the OO metrics.
