Study Notes

The text discusses the architecture of an agile system, which consists of three critical elements
Encapsulated modules are self-contained units with well-defined interfaces that conform to the passive infrastructure
Passive infrastructure provides drag-and-drop connectivity between modules, enabling rapid operational functionality
Active infrastructure designates responsibilities for maintaining agile operational capability in response to new requirements
Reusable design principles include encapsulated modules, facilitated interfacing, and reusable modules
Reconfigurable principles include peer-to-peer interaction, distributed control and information, and self-organization
Scalable principles include evolving infrastructure standards, redundancy and diversity, and elastic capacity
Agility measures include time to respond, cost to respond, predictability of response, and scope of response
The architecture enables rapid response to new requirements by facilitating the evolution and scalability of the system.
