Tube Process Mapping
"This is a method for documenting business processes, based on the design elements of the London Underground diagram. We have used this technique in place of standard flowcharts, for all kinds of process-related documents including quality systems, to give a fresh and user-friendly look to what can be rather boring material. If you want to give your company processes a new lease of life and get staff using them regularly, this really will help."
