Information Systems Development (ISD) covers a wide spectrum of methods and approaches (Avison et al. 2006), each aiming to make the process better and more successful. However, although ethics is seen as a core element with professional practice, it has yet to make an impact within the ISD process itself. This paper seeks to extend previous work, looking at the integration of the Ethical Grid (from Seedhouse 1991; Seedhouse 1998) into the three cycles of the Soft, Information Systems & Technologies Methodology (SISTeM). This is an attempt to integrate ethical thinking and considerations into the information systems development process.
