Ranking the refactoring Techniques Based on the Internal Quality Attributes

Abstract

The analytic hierarchy process (AHP) has been applied in many fields and especially to complex engineering problems and applications. The AHP is capable of structuring decision problems and finding mathematically determined judgments built on knowledge and experience. This suggests that AHP should prove useful in agile software development where complex decisions occur routinely. In this paper, the AHP is used to rank the refactoring techniques based on the internal code quality attributes. XP encourages applying the refactoring where the code smells bad. However, refactoring may consume more time and efforts.So, to maximize the benefits of the refactoring in less time and effort, AHP has been applied to achieve this purpose. It was found that ranking the refactoring techniques helped the XP team to focus on the technique that improve the code and the XP development process in general.

Decision-Making about Software Release Time Using Analytic Hierarchy Process

“…Jabali et al [6] proposed a method to select the best software architecture according to quality attributes by using the AHP. Alshehri et al [7] use the AHP for refactoring in XP (extreme programming). However, the AHP has not been applied to decision-making about software release time.…”
