Four design boundaries. The specific technology stack, data rights and operating model depend on the real environment.

DESIGN EXERCISE / FAILURE LAB

What happens when
the assumption breaks?

Choose a realistic failure condition to inspect a defensible response and the verification evidence it would require.

SELECT A FAILURE MODE

Scenario responses are authored reference examples and have not been measured in a customer environment.

RESPONSE CONTRACT01 / 02

Architecture response

Queue noncritical work and keep critical paths reliable.

HOW TO VERIFY

Burst tests and queue recovery.

TRADE-OFF TO ACCEPT

Degradation requires agreement about essential vs optional service.

BACK TO PRACTICE

Bring the constraints.
We can work through the decisions.
