The document describes a systems tools matrix that can help users select appropriate tools to achieve their learning objectives at different stages of the systems thinking cycle. The matrix sorts over 20 learning objectives into 4 categories aligned with complexity characteristics. Users first determine their learning objective(s) and where they are in the systems thinking cycle. They then use the color-coded matrix to match their objectives with recommended mapping, visualization, or conversational tools. The matrix provides guidance on tools that can help understand contexts and connections, identify patterns, and incorporate diverse perspectives when seeking to understand an issue, create a plan, or learn and refine.
