A Multistep Approach for Managing the Risks of Software Requirements Volatility

摘要

Software is changed continuously in order to respond to different users and business needs. Requirements are changed dynamically to improve software usability and increase its value, but requirement volatility sometimes cause failures for many projects because of inadequate understanding of the changing causes and the consequences of these changes. This research highlights the importance of managing requirement changes, classify them, and control the impact risks of requirement volatility on software project. The proposed model is designed based on software requirements risks factors and how to reduce their impacts. Generally, requirements changing is considered as a difficult, costly and time-consumed task, and consequently it is too important to study the inter-relationships between the changes and their impacts on the other phases of software system. The good understanding of the changing causes and their consequences can improve and support requirements management process and also lead successfully to the predicted goals of changes. The high quality of the requirements influences the success of a software project during software development and maintenance processes.
