Comparing Different Approaches for Identifying Crosscutting Concerns

Large-scale software applications are complex systems that involve myriad of different concerns .Ideally these concerns should be organized into different modules , but often some of these concerns crosscut each other .Identification of cross cutting concern in the beginning of each phase in software development lifecycle is very important . Crosscutting concerns identification has been neglected in software projects . This paper compares approaches such as Grounded Theory for Crosscutting Concerns Identification (GT4CCI), Discovering Early Aspects through Goals Interactions and Language Extended Lexicon (LEL) which can be a building block to identification of Crosscutting Concerns . Comparison is made on the basis of their type of requirement document which they accept and the end results .
