The issue of democracy in society is at the heart of our current concerns. The organizations and their information systems are also concerned by this issue. Democracy in organization requires a debate about norms, values and language encapsulated in the information systems. The participatory design approaches address this issue by proposing a democratic empowerment for users during design phase of projects. To go further, we propose a structured method to integrate democracy into information systems. This method named DEMOS for DEsign Method for democratic information System is described and then illustrated by a real experiment provided by a “lifelong training” service at the University. All aspects of the method are addressed: from elicitation phase to implementation. We particularly focus on techniques and tools used during the design phase.
