On aspect-oriented design-an approach to designing quality attributes

It is difficult to design software to meet its goal on quality attributes, because there are many factors related to quality attributes, and the relationships between these factors and quality attributes are quite complicated. However, we do not have a systematic way to design software considering quality attributes. Consequently, we have many troubles in the attainment of required quality attributes in actual software development. We are examining a design method, aspect oriented design (AOD) based on the idea of “aspect orientedness” proposed in the programming community as aspect oriented programming. In AOD, aspects corresponding to quality attributes are considered separately, and software architectures suitable for each aspect are designed independently and woven into the final architecture. The authors introduce their approach and demonstrate the effectiveness of the approach using an example
