+business concepts.

+
+
+### Domain Driven Design
+#### _How Does It Help?_
+* Placing the project's primary focus on the core domain and domain logic
+* Basing complex designs on a model of the domain
+* Initiating a creative collaboration between technical and domain experts to iteratively 
+refine a conceptual model that addresses particular domain problems
+* Bridge the gap between domain experts and developers by using the same language to 
+create the same understanding

+
+
+### Behavior Driven Development
+#### _What Is It?_
+Behavior-Driven Development (BDD) is a Test-First, Agile Testing practice 
+that provides Built-In Quality by defining (and potentially automating) tests 
+before, or as part of, specifying system behavior.

+
+
+
+### Behavior Driven Development
+#### _How Does It Help?_
+* Creates a shared understanding of requirements between 
+the business and the Agile Teams
+* Helps guide development, decrease rework, and increase flow
+* Creates business-facing scenarios that attempt to describe the behavior of a 
+Story, Feature, or Capability from a user's perspective.
