Hello,

Good point, they should be quite detailed and yet not overly complicated as to confuse the reader, it is essentially a form of management that is done to make sure tasks are on the way and are being done effectively. Project managers often use these to enhance and make an inference as to the progress of the projects being done. It is essentially like a liability coverage, so that if issues where to happen in the future, they can trace it back to the source and figure out what went wrong. Gnat charts should have detail be concise and get to the point. It should allow the reader to catch up with deadlines and progress as well as duration of projects and points that need to be done.
