This document provides an overview of systemic and visual tools for problem solving called PSVtools. It discusses using models and algorithms to facilitate information, practice, and application. The tools can help analyze and visualize problem situations from different angles to expand understanding of the problem's nature, structure, and dynamics. Visual thinking can also improve the quality of problem definition analysis. The document outlines 10 systemic principles of problem solving with PSVtools and provides examples of applying tools like mapping and metaphors to define and explore problem situations.
