If you want to think of these two views as being 'Enterprise Architecture' on the one hand and 'Startup Scrum like Good Enough for Now' on the other then that's fine so long as you also think about how each view can inform and be integrated into the other. Its that I'd like to describe.
The Chatauqua will meander through the current practices and arguments using this metaphor. They're abstractions and like all abstractions leaky. But we won't worry about that the metaphor will stay useful. But why Chatauqua?
When I was around 18* my local library in Maghull got a copy of Zen and the Art of Motorcycle Maintenance which had just been published. It was in the small Philosophy section which along with obscure foreign authors I used to backfill my education like a magpie and the picture on the back of a low slung motorbike with Pirsig and his son doing the thousand mile stare in monochrome was as shiny a book as I'd seen. Pirsig's peeling away of the layers of Classical and Romantic aspects and exposing Quality as the mutually supporting and unifying glue has stayed with me since. That and the anecdotes around engineering and writing that I'll repeat with the dole regularity of an old fart. Pirsig calls his book a Chatauqua from the travelling circus of educational talks and demonstrations of the 19th Century, a wagon train of TED Talks. That seems to describe what I'm intending to do and its all the more relevant (to me at least), that it was last year (2017) that Pirsig died.
Whether he'd enjoy or approve it though I don't know.
