Dynamic model for the system testing process

The approach for estimating and controlling the software testing effort presented in this paper is based on the theory of dynamical systems. The system testing process is modeled by a dynamical system to better understand its behaviour and to assist project and test managers in planning and tracking effort needs.The proposed model is based on worktime effort measurement and has been applied on three industrial software development projects data. In comparison to other models of the literature the worktime based system testing model describes the behaviour of the process more adequately. Consequently, decisions about the duration of system testing can be supported. Previous models from reliability modelling were selected for comparison. However, the emphasis here is placed on industrial experience on effort tracking and control.
