Abstract:

Living documentation is documentation that does not cease to be developed until the product ceases to develop. Living documentation can be produced at any time in multiple formats. The book, web pages and online help would continue to be developed as long as that development either solves inaccuracy or increases product usability and customer satisfaction.
