Diagram Standards

Inherit any Enterprise standards. However, these standards are often high-level, and implementation teams require more granularity with respect to standards and guidelines.

This page will be a living document that advocates for diagrams we will produce for each scope.

Theme: 4 R's

  • Right Time

Diagram Families

Selecting the right diagram is a skill in itself. There are several diagram families to choose from. The most frequently used are listed below. Hopefully you can rely on the skill of your architects to judge the right diagram type for the right audience that conveys the right level of information at the right time. (See 4 R's above)
