Alan Gawthorpe & I a talk last month on doing architecture with agile teams:
We did the session agile-style: We had cards for our topics, and the 'customers' in the audience prioritised. I think it worked okay, it would probably go smoother doing it a second time. Some of the significant books & articles that went into the slides were:
Agile Methodologies for the Enterprise
* Scott Ambler & Mark Lines - Disciplined Agile Delivery
* Scott's whitepaper on Agile@Scale
What does a technical architecture for agile look like?
* Coplien & Bjørnvig, Lean Architecture for Agile Software Development
* Poppendieck & Poppendieck, Lean Software Development: An Agile Toolkit
* http://alistair.cockburn.us/Walking+skeleton
The further reading list
* George Fairbanks, Just Enough Software Architecture
* The UK government's national audit office report on Agile Governance
