The collaborative action design approach of the Co_Lab, the Accelerator Lab of UNDP Argentina, involves all participants in the creation and implementation of experiments and interventions on the ground, not exclusively, but mainly at the grassroots and local levels. 

Using collective intelligence tools, this method promotes structured dialogue and leverages the participants' diverse knowledge and experiences. It is cost-effective, enhances coordination, and increases the legitimacy and adoption of actions. 

This approach allows for a broad portfolio of actions, with useful and scalable results from relatively few resources. The report explains the process and provides examples and resources for applying it to one's projects.
