Abstract
Problem
Agile values and practices provide diminishing returns as team size
increases
They sometimes devolve into rituals and methodology in order to
support larger teams and this causes more harm than good
In short, the rap is that Agile does not scale

Issues interacting with other teams to solve enterprise-level problems.
Integration points between modules within an application and across
applications were proving to be very painful and time consuming
