ddd (diary-driven development) is a tool to help solo software developers with software development. It is based on ideas of Andy Dent; specifically, that while there are well-defined procedures for software development in large organizations, there do not exist such procedures for solo software developers. The purpose of ddd is to formalize some of the process by having the developer write in “diaries”. These diaries help with the development of ideas and code while also serving as an archive for later perusal.

ddd is not currently under development.
