A key purpose of a Systems Architecture is to make explicit, and enable collective reasoning about, how all the physical, informational, operational, and transactional Components function together, and to reveal non-scalable legacy constraints. Although the Components are typically more visible, the underpinning structural relationships always have a disproportionate influence on the Systems’ operational capabilities and constraints.
Ensuring legacy structural relationships are capable of scaling to support very different future requirements is key to ensuring secure, reliable and cost-efficient operation at times of substantial transformation.
