For an Agile project to be successful, the architecture of the system has to reflect the needs of the process. You simply won’t be able to refactor constantly, accommodate changing business requirements, and so forth, unless your system is designed to accommodate those practices. This talk will look at the characteristics of an Agile design, and explore several design principles that will keep your design on track in an Agile environment. We’ll look, specifically, at the Single-Responsibility, Open-Closed, Liskov-Substitution, Dependence-Inversion, and Interface-Segregation principles.
