Aim is to establish the goal of data collection, which is refined into a series of questions which in turn suggest a set of specific metrics. Topic
The GQM method has four phases
Planing
during which the project for measurement application is selected, defined, characterised, and planned, resulting a project plan. http://ivs.cs.uni-magdeburg.de/sw-eng/us/java/GQM/phase1.shtml
Definition
during which the measurement programme is defined (goal, questions, metrics and hypotheses are defined) and documented. http://ivs.cs.uni-magdeburg.de/sw-eng/us/java/GQM/phase2.shtml
Data Collection
during which the actual data collection takes place, resulting in collected data. http://ivs.cs.uni-magdeburg.de/sw-eng/us/java/GQM/phase3.shtml
Interpretation
during which the collected data is processed with respect to the defined metrics into measurement results, that provide answers,to the defined questions, after which goal attainment can be evaluated. http://ivs.cs.uni-magdeburg.de/sw-eng/us/java/GQM/phase4.shtml
