Developing software demands high levels communication between possibly quite large number of stakeholders. While direct communication typically is preferred, but not always practicable. Benjamin Kovitz lists the following principal benefits of documentation in Practical Software Requirements.

Documentation

1. extends what the mind can grasp and remember
2. gives the same story to each member of the team
3. introduces new team members to the project
4. protects intellectual equity
5. helps the writer to better understand the problem

While the information about a software systems is unique, the basic structure of documents, especially to describe a software architecture, is not necessarily so. Teams communicating the structure and design principles may select a predefined structure, such as the arc42 Template, and smaller, much more confined templates for quality targets, views, and decisions. By selecting an existing structure authors and readers may save resources and are able to create value faster in a well-known environment.

For successfully communicating a software architecture it is important to drive the process of generating useful information from development artifacts automatically. This includes such classic living documentation artifacts as acceptance tests, but also static derived information as dependencies and system codes.
