Abstract: Abstract This study proposes the use of the visual, interactive and comparative analysis (VICA) methodology to encourage consensus-building in decision making processes involving multiple criteria and multiple participants working in cooperative groups. The tool was applied to the Electre TRI (VICA-Electre TRI) method which utilises comparative analyses plus visuals and the interactive exchange of individuals’ opinions within the group. It aims at reducing complexity, presenting updates about each member’s progress in the decision making process and fostering the search for consensus. The methodology was implemented in a spreadsheet format (Microsoft Excel) to make it as accessible as possible while also facilitating its acceptance and efficient use within organizations.
