Modifiability: Or Is There Design In Agility
Conference: Many people assume that agile methods mean an absence of design. Design still happens in agile projects, but it shifts from an up-front phase to a continual evolution. Design decisions should be left to the last responsible moment, but some design decisions do need to be made at the start of a project. Martin Fowler explores this topic through a panel discussion of design in an agile context.
Very good conference. 5 Software Architects talk about how to design software in a agile development.

Quote: “Test driven applications tend to organize themselves in a modular fashion. You cannot have unit testing without the ability to mock and stub objects. This ability and this need generates a better design. I use dependency injection due to this. ”
