Introduction to Agile Architecture

 

This course examines the relationship between the Agile methodology and the practice of Architecture. It is a mixture of lectures and exercises. The lectures provide instruction on the concepts and open up meaningful discussions; the exercises have students work through a case study to help deepen their knowledge. The course begins with defining what the Agile methodology and the practice of Architecture are and continues by looking at their strengths and weakness. An apparent dichotomy exists, and an exploration of industry practices demonstrate possible ways to resolve the conflict. The course ends by looking at how the best of both may be achievable.
