System diagrams are a very powerful systems thinking tool. Done well a system diagram can explain a problem and identify solutions on a single page, which could take a long document to put into words.
Because of its simple presentation it is a great aid to common understanding and communication, it is an excellent Board and Executive team presentation tool. Best benefits come from applying the technique to strategic and systemic problems at the division, organisation or initiative level.
