Documentation one of the most important part of a software project. It must provide a clear and coincise representation of the behavior of the system and should be written by the most expert developers and designers of the software project. Only then the documentation can be good, and at the same time, in the process of writing, inform the developers of semantical inconsistencies present in the system: because describing a system is debugging and auditing it at a very deep level. Inconsistent systems can't be clearly described.
