13. Given many medium to small software Deliverables, use Architecture to manage and integrate the Deliverables into a complete system.
This is a more specific statement of Principle #3; in Cascade, an Information System Architecture is used to integrate the two week deliverables, until a complete deliverable (component, sub-system) is assembled.
In parallel, a release schedule is a great approach to support delivery. Gather the usable deliverables into timed releases that go into production together. As per Principle #11, a Release each quarter is recommended. The business receives what they are paying for often enough to be of value, but not often enough such that assimilation of change is so frequent it causes chaos.
