An algorithmic-based software change effort prediction model using change impact analysis for software development

Software changes are inevitable due to the dynamic nature of the software development project itself. Some software development projects practice their own customised methodology but mostly adopt two kinds of methodologies; Traditional and Agile. Traditional methodology emphasizes on detailed planni...

An algorithmic-based software change effort prediction model using change impact analysis for software development
description Software changes are inevitable due to the dynamic nature of the software development project itself. Some software development projects practice their own customised methodology but mostly adopt two kinds of methodologies; Traditional and Agile. Traditional methodology emphasizes on detailed planning, comprehensive documentation and extensive design that resulted a low rate of changes acceptance. In contrast, Agile methodology gives high priority on accepting changes at any point of time throughout the development process as compared to the Traditional methodology. Among the primary factor that has direct impact on the effectiveness of the change acceptance decision is the accuracy of the change effort prediction. There are two current models that have been widely used to estimate change effort which are algorithmic and non-algorithmic models. The algorithmic model is known for its formal and structural way of estimation and best suited for Traditional methodology. While non-algorithmic model is widely adopted for Agile methodology of software projects due to its easiness and requiring less work in term of effort predictability.
