Design of Mixed Agile Project Considering Rework by Requirement Change

Abstract

Many IT venders need to adopt a mixture of waterfall and agile development, which is called mixed agile. In order to manage the mixed agile projects, project managers have to design the agility of the development process considering rework caused by requirement change. This study proposes a design method for mixed agile project. To be concrete, a new model to represent the agility for simulation of mixed agile process is proposed and a simulator which evaluates the mixed agile project based on the agility model is developed. A case study shows a demonstration of project design using the proposed method. The sensitivity analysis in changing the product 's structure and the process's agility is conducted and the result shows the usefulness and availability of the proposed method.
