Chapter 3: Harmony/ESW Principles and Practices
	Harmony Core Principles
		Your Primary Goal: Develop Working Software
		Measure Progress against the Goal, Not the Implementation
		Your Primary Measure of Progress Is Working Software
		Don\'t Put Defects in Your Software!
		Continuous Feedback Is Crucial
		The Five Key Views of Architecture
		Supplementing Your Architecture with Secondary Architectural Views
		Plan, Track, and Adapt
		The Leading Cause of Project Failure Is Ignoring Risk
		Continuous Attention to Quality
		Modeling Is Crucial
		Optimizing the Right Things
	Harmony Core Practices
		Incrementally Construct
		Use Dynamic Planning
		Minimize Overall Complexity
		Model with a Purpose
		Use Frameworks
		Prove the System under Development Is Correct—Continually
		Create Software and Tests at the Same Time
		Apply Patterns Intelligently
		Manage Interfaces to Ease Integration
		Use Model-Code Associativity
