Empirical Evaluation of Modified Agile Models

Empirical evaluation is one of the widely accepted validation method in the domain of software engineering which investigates the proposed technique via practical experience and reflects its benefits and limitations. Due to various advantages, agile models have been taking over the conventional software development methodologies since last two decades. However besides the benefits, various limitations have been noticed as well by the researchers and software industry in agile family. To achieve the maximum benefits it is vital to fix the limitations by customizing the development structure of agile models. This paper deals with the empirical analysis of modified agile models called Simplified Extreme Programing (SXP) and Simplified Feature Driven Development (SFDD), which are the modified forms of Extreme Programing (XP) and Feature Driven Development (FDD). SXP was presented to eliminate the issues of conventional XP such as, lack of documentation, poor architectural structure and less focus on design. SFDD was proposed to take care of reported issues in FDD such as explicit dependency on experienced staff, little or no guidance for requirement gathering, rigid nature to accommodate requirement changes and heavy development structure. This study evaluates SXP and SFDD through implementing client oriented projects and discusses the results with empirical analysis.
