Performance Analysis in Early Design Stage of Software System

Abstract: This study aims to deliver a user-friendly environment which allows architects to analyze the performance of software systems during early design stages. Design science method is used for developing the environment which consists of a UML design tool and a component for performance analysis. To evaluate the usability of the environment, a user study is conducted. All users’ feedback was collected and analyzed. The results show that the perceptions regarding the usability were not that good as expected. Suggestions on future research and implementation are also reported in this study.
