Component Metrics to Measure Component Quality

Recently, component-based software development isgetting accepted in industry as a new effective softwaredevelopment paradigm.Since the introduction ofcomponent-based software engineering (CBSE) in later90's, the CBSD research has focused largely oncomponent modeling, methodology, architecture andcomponent platform.However, as the number ofcomponents available on the market increases, it becomesmore important to devise metrics to quantify the variouscharacteristics of components.In this paper, we propose metrics for measuring thecomplexity, customizability, and reusability of softwarecomponents.Complexity metric can be used to evaluate thecomplexity of components. Customizability is used tomeasure how efficiently and widely the components can becustomized for organization specific requirement.Reusability can be used to measure the degree of featuresthat are reused in building applications.We expect thatthese metrics can be effectively used to quantify thecharacteristics of components.
