Synthetic Experiment in Evaluating the Usability Factor of the Requirement Change Propagation Process Model

The proposed requirement change propagation ( ReChaP ) approach promotes significant supports in simplifying the tedious tasks of requirement change propagation to other software artefacts during software evolution. One of the ReChaP’s pillars is the process model, which provides systematic guidelines to simplify the phenomenally time consuming and expensive efforts of the requirement change propagation process. This paper specifically reports on the preliminary results and the observation analysis for the conducted synthetic experiment in academic settings. The experiment’s goal is to evaluate the usability quality factor of the process model in terms of five main criteria; efficiency, effectiveness, learnability, satisfaction and usefulness. Our initial findings observe that the proposed ReChaP process model is soundly demonstrated as sufficiently usable, practical enough, and meantime has ideally achieved reasonable percentages for the five comprehensive criteria of the measured usability factor.
