Description

Paddy Fagan and Eamonn Moriarty introduce Watson Care Manager and the technology, team, and development process with a particular focus on the decisions at the inception of the project that had a direct impact on its architecture and evolution. They explore two particular architectural refactorings that the company undertook, the background, how the value was described to stakeholders, and the impact they had. You’ll learn how these individual changes were also part of a larger plan for the architectural evolution of the project. Paddy and Eamonn place the work in the context of more recent publications on evolutionary architecture and how the approach and execution maps onto the concepts of evolutionary architectures.
