- [Narrator] I'd like to continue looking at the Single Responsibility Principle. Remember the part that's tricky about this is always identifying the right level of abstraction. To understand what single means, I'll show some more of the general responsibility assignment software principles. There are a number of principles for determining what counts as responsibility. Previously, I talked about the controller of a use case or story and the creator of complex objects. Here I'll talk about two more concepts. Using high cohesion as a reason for combining objects, attributes or methods or using indirection that is a bridge or a link among separate objects.
