The proponents of Aspect Oriented Software Development (AOSD) methodology have done
a tremendous amount of work to bring out the positive effects of its adoption using
quantitative assessment. A structured assessment of the methodology requires a well-defined
quality model. In this paper, an AI agent based quality model has been proposed to
evaluate the effect of aspectization. The model has been applied on already existing
and equivalent versions of object oriented and aspect oriented case study application,
university automation software. Specific metrics for the software design properties
have been measured using AI agents for the different versions and were used to infer
upon the effect on quality. Based on the initial measurement, it was found that aspectization
has positively improved all the three quality attributes defined in the quality model.
The attributes of evolution and reusability showed significant improvement in quality
due to the effect of aspectization.
