Hello I am a bit confused about the emergent requirement type from Lecture 3a. It seems to have 2 very different definitions. On slide 10 it defines emergent as "requirements that cannot be addressed by a single component but depend on the interoperation of components" And on slide 42 it defines emergent as a type of volatile requirement from improved understanding of the problem. What's the best way to distinguish between them? Do we refer to the former as an emergent requirement and the latter as a volatile, emergent requirement? Or is it best to just always clarify the context? Thanks Adrian.
