Engineering practices make change efficient, repeatable, and accountable.

Delivery preserves verified artifacts and separates deploying a change from releasing it to users.

Architecture favours cohesive services, shared capabilities, explicit interfaces, and bounded coupling across instances, services, and providers.

Quality is designed into products and services, demonstrated through evidence, and improved through risk and data.

Services anticipate change and failure while remaining diagnosable, scalable, and recoverable.

Systems protect their operation and data by limiting access and exposure throughout their lifecycle.

Data remains trustworthy and subject to its jurisdiction requirements throughout its lifecycle.

A system's economic and environmental impacts remain proportionate to the value it delivers.
