ARCHITECTURAL PRINCIPLES

Principles

	In each principle, clearly state a chosen direction
	Each principle should be stated in such a way that you will know if the architecture has the characteristics expressed by the principle
	Each principle should have a counter-argument; that is, they should not be platitudes or general features that are desirable regardless of the system
	Principles should be simply stated and understandable
	Principles need to be rationalized, stating why the principle is preferred, drawing on business-related factors where possible
	The implications of adopting the principle should also be identified
	Base principles on experience (graphical history, literature, etc.) to repeat what worked and avoid what did not work
	For each quality goal, consider whether there is a principle that will guide structuring decisions to achieve the goal
