The main objective of this project is to apply consensus tools in order to make the decision making process in SMEs easier. Therefore, you will find a wide section dedicated to research upon the field of group tasks, consensus and decision making. The reader will be put into context regarding the current situation of SMEs in the region of Catalonia, Spain. Conclusions obtained during the whole process of research will be later used to try and decide how can they be applied to help this companies solve some of the main issues that they are facing. A survey will be conducted in order to determine what kind of factors can be associated to determined profiles, which will later be useful for the final purpose of the project. A deep look will also be taken at the concept of collective intelligence (CI), which is defined by the global intelligence of a group of individuals who work together to carry out different tasks. An experiment will be set in order to, at least, identify some of the main features pointed out of conclusions of the research in the field of CI. As a final step, a tool will be designed in order to help these companies in the process of forming groups which will later have to take part in decision making and problem solving processes. In order to design this tool, the knowledge previously obtained in the rest of the project will be used.
