Decision and risk register
Clarify the decision and its constraints.
CAPABILITY 06 / 07 Govern
Good architecture reduces uncertainty.
Turn constraints, competing priorities and delivery risks into concrete decisions teams can test and revisit.

THE ENGINEERING QUESTION
What should be decided before a major investment?
Technology choices are a consequence of how a system should behave, fail, recover and evolve. Explore three starting situations to see the decision, the risk and the verification that would make it credible.
INTERACTIVE / DECISION STUDIO
Change the constraint.
Change the engineering choice.
These are conceptual design exercises, not evidence of an actual client delivery. Choose a situation to examine its architecture implications.
ENGINEERING RESPONSE01 / 03
Recommended starting boundary
Validate the riskiest hypothesis first
THE FAILURE TO AVOID
Broad roadmaps can conceal unproven assumptions.
EVIDENCE TO REQUEST
Prototype, owner review and decision record.
PRACTICAL OUTPUTS
Leave with decisions,
not just diagrams.
These are typical deliverable categories, not a claim that a specific client engagement is complete.
Executable roadmap with gates
Define the contracts and ownership that make the decision operable.
Independent technical review
Verify behavior, failures, evidence and change safety.
