In Pragmatic Tracker, since we have many different measures available all with their own characteristics, we decided to use a very simple traffic light system based on the percentage reduction in distress from where one starts. This provides a simple, useful clinical guide to whether a client is moving in the right direction - by a lot (green), by a bit (amber) or hardly at all or deteriorating (red). Clients at risk are highlighted right across the client list window. Read a more detailed explanation here.
