Architecture vs. Design in Agile: What’s the Right Answer?

Is architecture the same as preliminary design in agile? It shouldn't be. Do we create architecture up front, then do iterative development after the architecture is done? That is edging back toward waterfall. Can you explain the purpose of the architecture in just two or three statements? Anthony Crain says that when he asks that question, he gets either verbose answers or blank stares. So Anthony shares an elegantly simple two bullet explanation of what an architecture does. Explore the models architects and designers should produce and learn why these models are so important to keep separate. Understand why it is vital to separate functional from nonfunctional requirements and how this affects architecture, design, and even code and test. Explore what a conceptual architectural model should look like vs. a physical one, and for the conceptual design model vs. a physical one—and the timing of all four models. Finally, examine the impact of iterative development on architecture.
