This paper models consensus formation processes using multi-agents simulations. The use of artefacts in the formation of consensus is investigated. This approach allows the study of complex team dynamics. We found that through the consensus process there are phases characterised by the efficiency of team meetings and the productivity of team members. We show that artefacts can play a significant role to improve the time to reach consensus. Furthermore, teams that use artefacts can significantly reduce the effects of bad team structure. Different team structures are investigated and characterized based on how well it supports the consensus formation process.
