The Participatory System Mapper (PRSM for short) is a web app that makes it easy for a group of people working together to draw networks (or 'maps') of systems.
The network or map can be anything that has items (or 'factors' or 'nodes') connected by links (or 'edges'). Here are some examples:
The software is aimed at people who are interested in understanding whole systems. Wikipedia defines a system as "a group of interacting or interrelated entities that form a unified whole".
The app is designed to enable groups of people, each using their own computer (or tablet) to collaborate in the drawing of a map. They may be sitting around a table, discussing the map as it is created face to face, or working remotely, using audio or video conferencing. Everyone can participate because every edit (creating nodes and links, arranging them and so on) is broadcast to all the other participants as the changes are made.
When you start the app in your browser, a 'room' is created for you in which to draw your network. You can add other users to this room to share the work. Only those with access to the room can see what is being created.
