    Systems Thinking to Manage Complexity


about us

We help decision making through systems thinking. Using both graphical tools  (conceptuals maps, mind maps and causal loop diagrams) and operative tools (system dynamics), we identify patterns and dynamics to understand disfuncionalities, decide actions and monitorize results. We build decision making environments.

We propose comprehensive solutions for a consistent action integrated in the environment. We call this Systemic Change and Transition Design.

In 22SISTEMA we help organizations to develop their vision as a system, and their imbrication in the wider systems they are part of.
