Principles

The architectural principles section allows you to highlight those principles that have been used (or you are using) to define the architecture. These could have been explicitly asked for or they could be principles that *you* want to follow. Example principles include; architectural layering, use of frameworks and libraries, common design patterns and templates for building components and common approaches (e.g. error handling, logging, etc).

Principles help you to introduce consistency and clarity into a software project, so it's important that everybody on the team has a common understanding of them.
