Our model for components method is the Goal/Question/Metric (GQM) Goal Template . The GQM method was defined as a mechanism for defining and interpreting a set of operation goals, using measurement. It represents a systematic approach for tailoring and integrating goals with models of the software processes,products and quality perspectives of interest based upon the specific needs of a project and organization. However, here, we will only use the parameters of a goal to characterize the types of studies performed. There are four parameters the object of study, the purpose, the focus, and the point of view. A sample goal might be: analyze perspective based reading (object of interest), in order to evaluate (purpose) it with respect to defect detection (focus) from the point of view of quality aMUUMQE (point of view). Studies may have more than one goal but the goals are usually related, i.e. there are several focuses of the same object being analyzed or a related set of objects are being studied. In experimented papers, the point of view is usually the researcher trying to gain some knowledge.
