A Quantitative Model for Improving the Effectiveness of the Software Development Process using Refactoring

Software development is a mentally complicated task. Different software development methodologies and quality assurance methods are used in order to attain high quality, reliable, and bug free software. eXtreme Programming (XP) is a software development discipline in the family of agile methodologies that contributes towards quality improvement using dozen practices. One of the important practices in XP is Refactoring. Refactoring which can be defined as “a change made to the internal structure of software to make it easier to understand and cheaper to modify without changing its observable behavior”. Although there has been a large amount of research investigations for this concept, but there has been little work done in quantitative approach. The main objective of the research is to develop a software development model using Refactoring practices. This work also shows the evaluation of effectiveness of the proposed software development model.
