I'm going to write-up my notes from the last London user group (Sharing Architectures) later in the week, but I wanted to pose a question to you that I asked at the user group. How big is your software architecture document for your current project/system and what sort of information does it contain? Here's a graph summarising the size responses from the user group (small turnout this month).
As you can see, most people's software architecture documents are ~50 pages and above, which my experience suggests isn't uncommon. How does this compare to yours and does anybody read these documents?
