I don't assume that someone knows the context, I assume that they could understand the context if they looked at it - that it can be explained to them to a useful extent. Because if you don't understand that, then your understanding of the problem space is not going to be sufficient for any useful purpose. And if you're a manager, then the company fucked up by putting something technically complex within your purview.
